Thrust needle roller bearings

Needle roller thrust bearings – high load capacity with minimal space requirements

Needle roller thrust bearings are specialized rolling elements that provide an excellent alternative to thrust ball bearings in space-constrained applications. Their primary advantage is a significantly higher axial load capacity, achieved while maintaining a very small cross-section. At e-marat.pl, we offer a wide assortment of assemblies and washers that allow for precise shaft bearing arrangements under heavy single-direction and double-direction loads.

Depending on the technical requirements of the bearing arrangement, these bearings can be configured in various variants:

• AXK needle roller and cage thrust assemblies – can run directly on hardened thrust surfaces, allowing for a maximum reduction in the overall dimensions of the bearing arrangement.
• AXW thrust needle roller bearings with a centering flange – an integrated solution that facilitates mounting and alignment.
• Systems with WS, GS rings or AS washers – allow the bearing to operate in cases where the adjacent thrust surfaces are not hardened.

Design and technical properties

Each needle roller thrust bearing features a rigid design resistant to heavy pressures. Although they possess slightly lower speed ratings than ball models, they compensate for this with operational stability under heavy loads. A standard AXK assembly can be supplemented with AS washers (1 mm thickness) made of hardened spring steel, which represents an economical and effective solution in less demanding arrangements.

Available configurations at e-marat.pl:

• Single-direction – accommodating axial forces in one direction only.
• Double-direction – consisting of two AXK assemblies and an intermediate ZS washer, for operation under alternating directions of force.
