Thrust Ball Bearing Supplier

High Axial Force Absorption in Standardized Designs

Axial force specialists. Consisting of shaft washers, housing washers, and ball and cage assemblies, these bearings are designed to handle heavy thrust loads acting parallel to the shaft center axis, preventing axial displacement.

We supply premium thrust ball bearings conforming to your choices and applications. From single-direction designs (51100, 51200 series) to double-direction configurations configured to locate the shaft axially in both directions, we guarantee high-precision performance under load.

Bearing Selection & Sizing Guide

Critical engineering parameters, structure details, and operating limits to help you select the ideal component.

Axial Load Capacity

Engineered specifically to support high thrust forces acting parallel to the shaft center axis, preventing axial movement and guaranteeing shaft stability.

Three-Part Demountable

Composed of distinct components (shaft washer, housing washer, and ball-and-cage assembly) allowing for independent mounting and straightforward maintenance.

Precision Sizing

standardized metrics ensure quick compatibility with ISO and DIN guidelines, guaranteeing perfect fitment inside motors, steering columns, and crane hooks.

Target Environments

Common Industrial Applications

These bearings are engineered to deliver reliable rotation and support critical equipment in harsh sectors, including:

Crane Hooks

Handles massive downward axial weights from suspended industrial loads while rotating smoothly.

Steering Columns

Supports oscillating rocker arm pivots inside high-RPM internal combustion engines.

Spindle Machinery

Sustains high pressures inside gear pumps and compact axial piston pumps.

Power Tools

Fits inside the tight gear housings of hand drills, angle grinders, and chainsaws.

They are designed specifically to handle heavy axial (thrust) loads acting parallel to the shaft axis. They cannot support any radial loads.
They are generally limited to moderate speeds due to centrifugal forces acting on the balls. For high axial loads at higher speeds, angular contact ball bearings are preferred.
Single-direction series can only handle axial loads in one direction, while double-direction series (incorporating a central shaft collar) support axial loads in both directions.
