INA AXK 1024 A 10x24x2 mm Axial Needle Roller and Cage Assembly

Technical Specification

Technical verification: The numerical performance values above correspond to the documented Schaeffler variant AXK1024-A/0-10. Compatibility with the designation AXK 1024 A without the additional suffix must be confirmed before using these values in engineering calculations.

Bearing Design and Construction

The INA AXK 1024 A axial needle roller and cage assembly consists of a thin steel cage containing cylindrical needle rollers arranged radially around the bearing axis.

The needle rollers operate between two flat raceway surfaces, transmitting axial forces through rolling contact.

Unlike a complete axial needle roller bearing assembly with separate washers, the AXK cage assembly does not incorporate its own bearing rings.

Compact Axial Design

The assembly has an axial height of only 2 mm.

This makes it suitable for mechanical arrangements where installation space in the axial direction is limited.

However, the total installed height may exceed 2 mm when additional axial bearing washers are used.

The dimensions of all mating components must be included when calculating the overall bearing arrangement.

Steel Cage Construction

The steel cage maintains the circumferential spacing and radial positioning of the needle rollers.

Its function is to guide the rolling elements and prevent direct contact between adjacent rollers during operation.

Operating conditions must account for cage material, lubrication, temperature and mechanical loading.

Raceway Requirements

The AXK needle roller assembly requires suitable raceway surfaces on both sides.

These surfaces must meet the manufacturer's requirements for hardness, surface finish and geometrical accuracy.

Where the surrounding machine components cannot provide suitable raceways, separate axial bearing washers should be used.

Insufficient raceway hardness or poor surface finish can cause premature wear and reduce bearing service life.

INA AXK 1024 A Designation Explained

AXK – Axial Needle Roller and Cage Assembly

AXK identifies an axial needle roller and cage assembly designed to transmit thrust loads.

10 – Nominal Inside Diameter

The first dimensional code indicates a nominal cage inside diameter of 10 mm.

24 – Nominal Outside Diameter

The second dimensional code identifies a nominal cage outside diameter of 24 mm.

A – Manufacturer Design Variant

The A suffix forms part of the INA product designation.

Its precise technical significance should not be assigned to a particular material or dimensional modification without reference to Schaeffler documentation.

Additional Designation /0-10

Schaeffler documentation also identifies the variant AXK1024-A/0-10.

The additional /0-10 suffix relates to needle roller dimensional sorting.

It should not automatically be omitted when identifying or ordering an exact manufacturer variant.

Load Ratings and Operating Performance

These values relate to the documented AXK1024-A/0-10 configuration and require confirmation for the exact supplied variant.

Axial Load Capacity

The assembly is designed to accommodate axial forces acting in one direction.

The published load ratings are based on standardized calculation criteria and specified operating assumptions.

Actual service life depends on loading, raceway quality, lubrication, temperature and mounting accuracy.

Radial Loads

The AXK axial needle roller assembly is not designed to support radial loads.

If radial forces are present, the mechanical arrangement must incorporate an appropriate radial bearing.

Operating Speed

Reference and limiting speeds are catalogue values.

The permissible operating speed depends on lubrication conditions, applied load, operating temperature and the design of the complete bearing arrangement.

INA AXK 1024 A vs INA AS 1024 Axial Washer

The AXK needle roller and cage assembly can operate with suitable axial bearing washers.

The AS 1024 washer is not a rolling element assembly and cannot replace the AXK 1024 A cage assembly.

The use of one or two washers depends on the design of the bearing arrangement and the suitability of the surrounding raceway surfaces.

Bearing Selection and Mounting Requirements

Correct selection of INA AXK 1024 A requires evaluation of the complete thrust bearing arrangement.

Important factors include:

• Magnitude of the axial load.

• Direction of the applied thrust force.

• Operating speed.

• Raceway surface hardness.

• Raceway surface roughness and geometrical accuracy.

• Lubricant type and supply method.

• Operating temperature.

• Available axial installation space.

• Cage guidance and centring conditions.

Mounting Without Separate Washers

Direct installation is possible when the surrounding machine components provide raceway surfaces that meet Schaeffler's technical requirements.

The mating surfaces must have suitable hardness, surface finish and dimensional accuracy.

Mounting With Axial Bearing Washers

Where the machine components cannot provide suitable raceways, separate axial bearing washers should be installed.

INA AS 1024 is a corresponding washer designation for the AXK 1024 size.

The required number of washers depends on the arrangement and the properties of the mating components.

Lubrication

The axial needle roller and cage assembly requires appropriate lubrication.

Grease or oil may be selected according to operating speed, loading, temperature and application requirements.

The assembly should not be assumed to contain sufficient factory-applied lubricant for its entire service life.

Industrial Applications

AXK-series axial needle roller and cage assemblies are used in compact mechanical systems requiring axial load support.

Typical application categories include:

• Mechanical gearboxes.

• Adjustment mechanisms.

• Screw-driven assemblies.

• Axial feed mechanisms.

• Compact industrial drives.

• Production machinery.

• Equipment with restricted axial installation space.

These are general application categories for AXK-type assemblies. Suitability of the exact INA AXK 1024 A variant must be verified against the operating requirements of the intended equipment.

Alternative Product Designation Formats

The following formats may appear in technical documentation, ERP systems and industrial procurement searches:

• INA AXK 1024 A

• AXK 1024 A INA

• AXK1024-A

• AXK1024 A

• INA AXK 1024 10x24x2 mm

• AXK 1024 A axial needle roller bearing

Schaeffler documentation also includes the designation AXK1024-A/0-10.

This should be treated as a specific manufacturer variant rather than automatically confirmed as identical to every product identified as AXK 1024 A.

FAQ – Frequently Asked Technical Questions

1. What are the dimensions of INA AXK 1024 A?

The assembly has a nominal inside diameter of 10 mm, outside diameter of 24 mm and axial height of 2 mm, expressed as 10x24x2 mm.

2. Is INA AXK 1024 A a complete thrust bearing?

No. It is a needle roller and cage assembly that requires suitable mating raceways or additional axial bearing washers.

3. What loads can AXK 1024 A accommodate?

The assembly is designed for axial loads acting in one direction. It is not a substitute for a radial bearing.

4. What are the load ratings of INA AXK 1024 A?

For the documented AXK1024-A/0-10 variant, the basic dynamic axial load rating is 9.2 kN and the basic static axial load rating is 25.5 kN.

5. Is an AS 1024 washer required?

A washer is required where the mating machine surface does not meet the requirements for a bearing raceway. The number of washers depends on the arrangement.

6. What material is the cage made from?

The cage is made from steel.

7. Can AXK 1024 A support axial loads in both directions?

Not as a single-direction assembly. A bearing arrangement intended to accommodate thrust loads in both directions must be designed accordingly.

8. Are AXK 1024 A and AXK1024-A/0-10 identical designations?

They should not automatically be considered identical. The /0-10 suffix is an additional manufacturer designation that must be considered when identifying the exact variant.
