JX-YCF Precision Bearing Lock Nuts – 30° Flank-Locking Type

JX-YCF Precision Bearing Lock Nuts – 30° Flank-Locking Type

High-Precision SCM440 Shaft Locknuts with Brass Locking Elements for Machine Tool Spindles, Ball Screws and Bearing Retention

JUXIN FASTENERS supplies JX-YCF Series precision bearing lock nuts for high-accuracy mechanical assemblies requiring reliable axial positioning and controlled locking of threaded shafts.

The JX-YCF design belongs to the family of flank-locking precision locknuts. Its locking mechanism uses brass locking elements actuated by screws arranged at approximately 30° to the thread-locking interface.

The mechanism is designed to press the brass elements against the mating shaft threads while minimizing unwanted deformation of the nut's main threaded body.

Unlike ordinary all-metal prevailing-torque nuts, precision flank-locking nuts use a separate mechanical locking arrangement that is tightened after the nut has been positioned on the shaft.

The original JX-YCF specification identifies SCM440 (42CrMo4) alloy steel, HRC 28–32 hardness, 

ISO 4H internal thread accuracy and precision face-runout values of 0.002–0.005 mm, depending on the manufacturing and inspection requirements.

Typical applications include machine tool spindles, precision bearing assemblies, ball screw support bearings, rotary axes and industrial motion-control equipment.

Product Technical Specifications

Important Specification Qualification

The listed accuracy values describe the supplied technical specification and comparable manufacturing grades.

 Final tolerances, inspection methods and acceptance limits must be confirmed for the actual JX-YCF part number.

What Is a Flank-Locking Precision Bearing Nut?

A flank-locking precision bearing nut is a threaded shaft-retention component that uses a dedicated locking mechanism to secure the nut after its axial position has been established.

The nut is first threaded onto the mating shaft.

After the required axial position or bearing adjustment is reached, the locking screws are tightened.

These screws apply force through brass locking elements to the shaft's external thread flanks.

This arrangement provides a controlled locking action without relying on the permanent deformation of the nut's main internal threads.

Engineering Advantages

• Controlled shaft-thread locking.

• Precision axial positioning.

• Potential reduction of damage to mating shaft threads.

• Suitable for selected repeated adjustment applications.

• Compatibility with precision bearing-retention designs.

• High-accuracy machined bearing-contact surfaces.

• Customizable thread and dimensional configurations.

Important Engineering Limitation

The locking mechanism does not eliminate the need to verify bearing preload, axial load, screw tightening torque or shaft-thread strength.

30° Flank-Locking Mechanism

The JX-YCF locking concept uses brass contact elements positioned to engage the mating shaft thread flanks.

The original technical description identifies a locking angle of approximately 30° and three distributed locking locations.

Operating Principle

1. Thread the precision nut onto the mating shaft.

2. Position the nut against the specified bearing or mechanical component.

3. Establish the required axial location or bearing preload.

4. Tighten the locking screws according to the approved procedure.

5. Allow the brass locking elements to contact the shaft thread flanks.

6. Verify the final assembly position and locking condition.

Why Brass Locking Elements?

Brass is softer than many hardened steel shaft materials.

A correctly designed brass contact element can conform to the thread flank and distribute locking pressure.

This may help reduce localized thread damage compared with direct steel set-screw contact.

However, thread protection depends on the actual brass element geometry, shaft material, surface hardness and applied locking force.

Why Use a 30° Locking Arrangement?

The angled locking arrangement is intended to direct locking force toward the mating thread flank while limiting undesirable disturbance of the precision nut's axial position.

The effectiveness of this mechanism depends on the actual thread profile, contact geometry and screw arrangement.

Important Distinction

The 30° value refers to the locking geometry, not operating temperature.

Three-Point Locking Design

Three distributed locking locations may provide a more balanced locking arrangement than a single contact point.

For precision shaft applications, the distribution of locking force can influence the final alignment and retention of the assembly.

Critical Design Parameters

• Angular spacing of locking positions.

• Brass insert geometry.

• Locking screw diameter.

• Locking screw thread.

• Screw tightening torque.

• Nut body stiffness.

• Shaft-thread accuracy.

• Nut-to-shaft thread clearance.

• Bearing contact-face geometry.

Engineering Warning

Three-point locking does not automatically guarantee zero movement, zero runout or unlimited vibration resistance.

The complete shaft assembly must be validated.

SCM440 (42CrMo4) Alloy Steel

The JX-YCF nut body is specified as SCM440 alloy steel.

SCM440 is a chromium-molybdenum alloy steel used in mechanical components requiring a combination of strength, toughness and machinability after appropriate heat treatment.

42CrMo4 is a commonly referenced European chromium-molybdenum alloy steel grade.

Important Material Qualification

SCM440 and 42CrMo4 are closely related engineering material designations, but exact chemical composition, 

heat-treatment requirements and certification must be checked before claiming complete equivalence.

Specified Hardness: HRC 28–32

The original product data specifies a Rockwell C hardness range of HRC 28–32.

This range should be verified by the approved manufacturing and inspection process.

Engineering Significance

Controlled material hardness can support the mechanical performance and dimensional stability of the precision nut.

However, hardness alone does not establish bearing preload capacity, fatigue resistance or locking torque.

ISO 4H Internal Thread Accuracy

The original specification identifies ISO 4H internal threads.

ISO metric thread tolerance classes define permissible deviations in thread dimensions.

A 4H internal thread tolerance class represents a precision internal-thread requirement.

Important Selection Requirements

• Nominal thread diameter.

• Thread pitch.

• Thread tolerance class.

• Mating shaft thread tolerance.

• Thread form.

• Thread direction.

• Functional engagement.

• Inspection method.

Engineering Insight

A precision internal thread must be matched with an appropriately specified shaft thread.

A 4H nut thread does not independently guarantee complete assembly accuracy if the mating shaft has excessive pitch error, form error or runout.

Precision Face Runout: 0.002–0.005 mm

Face runout is a critical parameter in precision bearing-retention applications.

It describes the variation of the specified reference face relative to the relevant rotational or thread datum during measurement.

Precision Ground Configuration

The original technical data identifies a face-runout reference of 0.002 mm.

Precision Turned Configuration

The original technical data identifies a face-runout reference of 0.005 mm.

Why Face Runout Matters

Excessive face runout may affect:

• Bearing-ring seating.

• Axial load distribution.

• Bearing preload consistency.

• Rotational accuracy.

• Spindle vibration.

• Assembly repeatability.

• Bearing service life.

Important Inspection Requirement

The drawing must identify the datum, measurement method, inspection fixture and acceptance criterion.

Do not assume that a stated 0.002 mm face-runout value applies to every nut diameter or manufacturing configuration.

Precision Grinding vs. Precision Turning

Precision locknuts may be produced using different machining processes.

Precision Grinding

May be selected when tighter control of critical bearing-contact surfaces and runout is required.

Precision Turning

May be suitable where the required tolerances can be achieved through controlled precision machining.

Selection Factors

• Required face runout.

• Thread accuracy.

• Surface finish.

• Nut diameter.

• Production volume.

• Inspection requirements.

• Manufacturing cost.

The manufacturing process should be selected according to the actual engineering requirements rather than by assuming that every application requires the tightest available tolerance.

Metric Precision Locknut Thread References

Precision bearing locknuts commonly use metric fine-pitch threads.

The following designations are found in the international precision locknut market and are useful for engineering comparison.

Availability Notice

These are market reference thread sizes, not a confirmed JX-YCF production range.

The original JX-YCF data does not provide a complete model-by-model dimensional table.

Actual thread sizes, outside diameters, nut heights, locking screw arrangements and manufacturing availability must be confirmed against the JUXIN FASTENERS drawing or catalog.

American Inch-Series Precision Locknut Requirements

American industrial customers may specify precision shaft locknuts using inch-based Unified threads.

Unlike general-purpose hex nuts, precision bearing locknuts often use fine or extra-fine threads because axial adjustment resolution and shaft geometry are important.

Potential thread systems include:

• UNF – Unified National Fine.

• UNEF – Unified National Extra Fine.

• UNS – Unified Special Thread Series, Where Applicable.

Common Inch Thread References

Important American Market Qualification

These are thread-system references for customer-specific engineering review.

They are not confirmation that the JX-YCF Series is currently manufactured in every listed inch size.

A custom inch-thread precision locknut requires confirmation of the shaft thread, bearing contact geometry, locking mechanism and inspection tolerances.

Metric and Inch Threads Are Not Interchangeable

Metric fine-pitch threads cannot be substituted with UNF or UNEF threads based only on nominal diameter similarity.

For example:

• M20 × 1.0 is not interchangeable with 3/4"-20 UNEF.

• M25 × 1.5 is not interchangeable with 1"-12 UNF.

• M12 × 1.0 is not interchangeable with 1/2"-20 UNF.

The complete thread specification must match the mating shaft.

JX-YCF vs. Conventional Bearing Locknuts

Conventional bearing locknuts may use a tab washer, keyway or other locking arrangement.

The JX-YCF Series uses a separate screw-actuated brass-contact locking mechanism.

Important Engineering Qualification

The JX-YCF design should not automatically be considered interchangeable with DIN 981-style bearing locknuts or other locking systems.

Dimensions, bearing-contact surfaces, thread specifications and axial load requirements must be verified.

JX-YCF vs. Ordinary All-Metal Self-Locking Nuts

Ordinary all-metal prevailing-torque nuts often use deliberate thread deformation or other interference features.

JX-YCF precision locknuts instead use separate brass locking elements actuated by screws.

Key Differences

• JX-YCF is designed for precision shaft positioning.

• Locking occurs after the nut is positioned.

• The brass elements act against the mating shaft thread flanks.

• The locking system requires a defined screw-tightening procedure.

• Precision face runout and bearing contact geometry are critical.

These differences make the JX-YCF Series a specialized precision component rather than a general-purpose replacement for distorted-thread hex locknuts.

Bearing Preload and Axial Positioning

Precision bearing assemblies may require controlled axial positioning or preload.

A precision locknut can be part of the mechanism used to establish and retain the required position.

Engineering Considerations

• Bearing type.

• Bearing arrangement.

• Shaft stiffness.

• Required preload.

• Thermal expansion.

• Nut contact-face runout.

• Mating shaft accuracy.

• Locking screw torque.

• Operating speed.

• Service temperature.

Critical Warning

The locking screws should not be used as a substitute for the approved bearing preload adjustment procedure.

Excessive preload can increase bearing temperature, friction and premature wear.

Insufficient preload may contribute to unwanted axial movement or reduced rotational accuracy.

Check axial position, runout, preload and locking condition as required.

Step 8 – Document Inspection Results

Record the relevant measurements for production or maintenance traceability.

Important Installation Warning

Do not invent a universal tightening torque for the JX-YCF Series.

Locking screw torque depends on nut size, screw diameter, thread geometry and the approved design.

Reuse and Maintenance

The brass-contact locking mechanism may permit repeated adjustment or removal when handled correctly.

However, repeated use should not be interpreted as unlimited reuse.

Inspection Before Reassembly

• Brass locking element wear.

• Locking screw damage.

• Internal thread condition.

• Mating shaft thread damage.

• Nut face condition.

• Corrosion.

• Surface contamination.

• Dimensional or runout changes.

Replace components that no longer meet the approved requirements.

Blackened Surface Finish
