AXK 1528 INA - Needle Roller Thrust Bearing 15x28x2

Application - Compact Axial Bearing for Industrial Systems

The AXK 1528 INA is a needle roller thrust bearing designed to support axial loads in compact mechanical assemblies. With dimensions 15x28x2 mm, this bearing is widely used in gearboxes, electric motors, clutch systems, machine tools, and other industrial applications where precise axial positioning is required.

Its extremely low cross-section height makes it ideal for installations with limited axial space. The AXK 1528 typically operates in combination with hardened thrust washers, forming an efficient bearing unit within a bearing housing or directly against properly prepared shaft and housing surfaces.

This design ensures reliable axial load handling in applications where radial loads are supported by a separate bearing arrangement.

Needle Roller Design - High Load Capacity with Minimal Height

Unlike a conventional ball bearing, a needle roller thrust bearing uses slender cylindrical rollers arranged in a cage. This construction distributes axial loads evenly and allows for higher load capacity relative to its height.

The AXK 1528 INA offers high durability under dynamic industrial conditions. Its precision-manufactured rolling elements provide smooth operation and consistent axial performance in continuous-duty systems.

The compact geometry makes it particularly suitable for industrial applications requiring minimal installation space without compromising load capacity.

FAQ - Frequently Asked Questions

What is the difference between a needle roller thrust bearing and a ball thrust bearing?
A needle roller thrust bearing provides higher axial load capacity with a lower installation height compared to a ball thrust bearing.

Does AXK 1528 require thrust washers?
Yes, it is typically used with hardened thrust washers that serve as raceways for the rollers.

Can this bearing support radial loads?
No, it is designed exclusively for axial loads. Radial loads must be supported by a separate bearing.

Where is AXK 1528 commonly used?
It is used in industrial machinery, transmissions, electric motors, and compact mechanical assemblies.
