Thrust Ball Bearings

Thrust ball bearings are specifically designed to bear axial loads. By replacing sliding friction with rolling friction, they significantly reduce the coefficient of friction, decrease wear, and extend equipment life. Their structure consists of a shaft ring, a housing ring, rolling elements, and a cage, with steel balls rolling freely between the raceways.

Thrust ball bearings can be equipped with different cage types: stamped steel cages are economical and durable, suitable for conventional loads and light- or medium-speed conditions; copper cages provide good thermal conductivity, wear resistance, and high rigidity, making them ideal for heavy-load or high-speed applications; plastic cages are lightweight, corrosion-resistant, and non-magnetic, suitable for special environments. Based on load direction, thrust ball bearings are classified into single-direction and double-direction types: single-direction bearings handle axial loads in only one direction, while double-direction bearings can withstand axial loads in both directions, offering greater application flexibility.

HSN bearings are available in a full size range from miniature to large sizes, covering series 52**, 53**, and 54**, meeting most axial load application requirements. With precise dimensional tolerances and consistent performance parameters, they can directly replace domestic brands such as ZWZ, LYC, and C&U of the same specifications, as well as imported brands such as SKF, FAG, and TIMKEN. Raw materials are rigorously selected, and key parameters—including raceway precision and steel ball roundness—are monitored throughout the entire production process using professional inspection equipment, ensuring stable operation. Custom drawings and sample measurements are supported, and both structure and materials can be optimized for special working conditions such as high temperature, corrosion, and heavy loads.
