The 51112 Single-Direction Thrust Ball Bearing is engineered to sustain heavy thrust or axial loads in one direction, operating with exceptional running accuracy and minimized power loss. It consists of a shaft washer, a housing washer, and a high-strength ball and cage assembly. This bearing is widely used in vertical shafts, rotating turn-tables, and heavy power transmission systems where rigid axial positioning and low friction torque are strictly required.

No. Single-direction thrust ball bearings like the 51112 are strictly designed to support axial loads acting in one direction only. They must not be subjected to any radial forces whatsoever, as radial loading can misalign the components and lead to premature failure.
Yes. While our standard 51112 comes equipped with a rugged pressed steel cage, we can customize production batches with machined brass cages for extreme heavy-duty environments, or reinforced nylon cages for lightweight or low-noise setups.
Our manufacturing plants are fully certified under ISO 9001:2015 global quality management criteria. We maintain tight tracking control from raw materials to final dimensional audits to guarantee uniform international consistency.
For moderate speeds, a high-quality lithium-based grease is highly effective. For higher operational speeds or environments with significant heat buildup, a continuous oil bath or circulating oil lubrication system is recommended to flush out friction heat.
