Thrust Bearing

Backed by a team of experts, we are engrossed in supplying Thrust Bearing that is an extremely resilient and rugged machine component. It is typically used in order to make the movement of the machine parts smooth and friction-less. The bearing consists of rollers that help position the moving components of a machine. Thrust Bearing can endure impacts, heat, and shock, therefore, it is sure to last for an extended period of time.

A thrust bearing, a type of rotary bearing, rotates between parts reducing friction and is designed to support an axial load (mostly in low-speed applications). It is the axial bearing that permits rotation between parts. 

Thrust bearings include a variety of bearings that assists axial loads or axial force. It is an axial bearing that permits rotation between parts. Thrust bearings support the axial thrust of both horizontal and vertical shafts. 

The functions are to prevent the shaft from drifting in the axial direction and to transfer thrust loads applied on the shaft.

Thrust bearings are generally seated against a raised thrust collar around the shaft. The thrust collar allows the axial load to be transferred from the shaft to the bearing. Thrust bearings are typically used in pairs on each side of the thrust collar.

Benefits to Thrust Bearings

• They offer high reliability
• Provide high load capacity in harsh environments
• Simple mounting - the shaft and housing washers can be mounted separately
• Provide a wide assortment
• Availability

General types

Single-direction thrust ball bearings

These bearings have balls enclosed in a cage between the shaft raceway washer that corresponds to the inner ring, and the housing raceway washer that corresponds to the outer ring. They can bear only single-direction axial loads.

Double-direction thrust angular contact thrust ball bearings

These can support axial loads in both directions, with high rigidity in the axial direction due to a large contact angle. Their structure is not suited to grease-lubricated vertical shafts.

Cylindrical roller thrust bearings

• These bearings use cylindrical rollers and have single-row, double-row, and three-row types for larger load capacities.
• They support axial loads only, are suited to high loads, and have high axial rigidity.

Needle roller thrust bearings

These include bearings using machined parts and bearings using pressed steel plate parts for the raceway washer, with the latter type having the smallest cross-sectional height and high load-bearing capacity.

Tapered roller thrust bearings

These are thrust bearings using tapered rollers. The single-type bearings include those with and without ribs on the housing raceway washers, as well as the full complement roller type. Double-type bearings are mainly used to support axial loads such as those on rolling mill roll necks.

Spherical roller thrust bearings

• These bearings have a self-aligning nature that uses barrel-shaped rolling elements, with a spherical surface on which the raceway surface of the housing raceway washer (outer ring) is centered on the guide sleeve. They can bear high axial loads.
• As there are many sliding surfaces such as the roller end surfaces and the cage, oil lubrication must be used even in low-speed operation.
