AXK 1528 15x28x2 Neutral - Thrust Needle Roller and Cage Assembly

AXK 1528 15x28x2 Neutral - Thrust Needle Roller and Cage Assembly

AXK 1528 15x28x2 Neutral is a thrust needle roller and cage assembly designed to accommodate axial loads while requiring very little axial installation space. The AXK1528 designation corresponds to a 15 mm bore diameter, 28 mm outside diameter and 2 mm needle roller diameter. AXK assemblies consist of needle rollers retained and guided by a cage and can operate with suitable thrust washers or properly prepared raceway surfaces.

AXK 1528 - product characteristics

The AXK series belongs to the family of thrust needle roller and cage assemblies. Its compact cross-section makes this bearing arrangement particularly useful where axial space is limited but axial load-carrying capability is required.

JTEKT describes the AXK design as a one-piece cage assembly. The manufacturer also confirms that thrust needle roller and cage assemblies have a very small cross-sectional height.

The product offered here is a Neutral version. Therefore, manufacturer-specific load ratings, limiting speeds or material specifications should not automatically be assigned to this product unless confirmed for the supplied batch.

AXK 1528 dimensions

The 15 mm, 28 mm and 2 mm dimensions are confirmed in the JTEKT/Koyo catalogue for AXK1528.

What does AXK 1528 mean?

AXK identifies a metric-series thrust needle roller and cage assembly.

For AXK1528, the principal catalogue dimensions are:

15 mm - inside diameter Dc1
28 mm - outside diameter Dc
2 mm - needle roller diameter Dw

JTEKT classifies AXK1528 specifically as a thrust needle roller and cage assembly, rather than a complete bearing supplied with two integral bearing rings.

AXK 1528 construction

An AXK thrust assembly uses needle rollers arranged radially around the axis and retained by a cage. The needle rollers provide the rolling contact required to transmit axial forces between the mating raceways.

A major advantage of this construction is its very low axial section height. JTEKT's technical catalogue states that AXK-series assemblies use a one-piece cage and that thrust needle roller and cage assemblies can operate directly against suitable raceway surfaces.

This makes AXK assemblies suitable for compact bearing arrangements where conventional thrust bearings would require more installation space.

AXK1528 and thrust washers

AXK1528 is the needle roller and cage assembly itself. Thrust washers are separate components.

For its own AXK1528, JTEKT lists several matching raceway components:

• AS1528 - thin thrust washer, 1.00 mm thick
• LS1528 - heavy thrust washer, 2.75 mm thick
• WS.81102 - shaft-piloted washer
• GS.81102 - housing-piloted washer

These references are useful when designing the bearing arrangement, but compatibility should always be checked for the actual Neutral product and application.

AXK 1528 vs AS1528

These two designations refer to different components.

AXK1528 is the thrust needle roller and cage assembly.

AS1528 is a thin thrust washer that can form a raceway for the rolling elements.

According to JTEKT, the corresponding AS1528 washer has an outside diameter of 28 mm, D1 of 16 mm and a thickness of 1 mm.

Therefore, when replacing a bearing arrangement, it is important to determine whether only the AXK1528 assembly is required or whether the thrust washers also need replacement.

Load ratings - important information for the Neutral version

Manufacturer-specific AXK1528 products may have published dynamic and static load ratings. For example, JTEKT specifies Ca 11.1 kN, C0a 35.2 kN and an oil-lubricated limiting speed of 15,000 min-1 for its AXK1528.

These figures must not be treated as guaranteed specifications for this Neutral AXK 1528.

For engineering calculations, load capacity, permissible speed, cage material and lubrication requirements should be confirmed for the actual supplied product.

Typical applications of AXK thrust needle roller assemblies

AXK-series thrust needle roller assemblies are intended for bearing arrangements where axial forces must be accommodated within a compact axial space.

Thrust needle roller bearings as a product family are used across industrial machinery and equipment. JTEKT lists needle roller bearing applications across machine tools, construction and agricultural machinery, automotive equipment and other industrial applications.

The suitability of this specific Neutral AXK1528 for a particular machine should be determined from the operating load, speed, lubrication, raceway design and installation conditions.

Raceway requirements

Because AXK1528 is a needle roller and cage assembly rather than a conventional bearing with integral inner and outer rings, the mating surfaces are an important part of the bearing arrangement.

Depending on the design, the assembly may operate:

• directly against suitably prepared raceway surfaces, or
• together with separate thrust washers.

JTEKT's AXK technical documentation specifically provides AS, LS, WS and GS washer options for this type of arrangement.

How to select an AXK 1528 replacement

When replacing an existing thrust needle roller assembly, check the complete designation AXK1528, the dimensions 15x28x2 mm, the required thrust washers or raceway surfaces and the operating conditions.

Matching dimensions alone do not guarantee identical performance. Load ratings, limiting speeds, cage construction and other technical characteristics may vary between manufacturers.

For this reason, parameters published for branded AXK1528 products should not automatically be transferred to a Neutral product.

Alternative designations and search references

The product may commonly be searched under variations such as:

AXK 1528
AXK1528
AXK 1528 15x28x2
AXK1528 15x28x2
AXK 15x28x2
thrust needle bearing AXK1528
thrust needle roller bearing 15x28x2
thrust needle roller and cage assembly AXK1528

These wording variations describe or identify the AXK1528 size but should not be interpreted as manufacturer-specific cross-references.

FAQ - AXK 1528 15x28x2

What type of bearing is AXK 1528?
AXK1528 is a thrust needle roller and cage assembly. It is intended primarily for carrying axial loads.

What are the dimensions of AXK1528?
The principal dimensions are 15 mm inside diameter, 28 mm outside diameter and 2 mm needle roller diameter, giving the commonly used size description 15x28x2 mm.

Is AXK 1528 a complete thrust bearing?
AXK1528 identifies the needle roller and cage assembly. Separate thrust washers may be required depending on the design of the surrounding components.

Which washer can be used with AXK1528?
For its AXK1528, JTEKT lists AS1528, LS1528, WS.81102 and GS.81102 washer options. Compatibility should be verified for the actual application.

Are AXK1528 and AS1528 the same component?
No. AXK1528 is the needle roller and cage assembly, while AS1528 is a thin thrust washer.

Does AXK1528 carry radial loads?
The AXK series is a thrust bearing arrangement intended for axial loading. Radial loads must be supported by an appropriate radial bearing arrangement.

Can load ratings from JTEKT or another manufacturer be used for this Neutral AXK1528?
Not as guaranteed specifications. Manufacturer-specific ratings should only be used for that manufacturer's product unless equivalence has been technically confirmed.
