S V Hi-Tech Bearing (India) Private Limited

Combined needle roller cylindrical roller thrust bearings consist of a radial needle roller bearing paired with an axial cylindrical roller thrust bearing. This unique combination supports both high radial and axial loads simultaneously within a single compact unit. Designed for applications with limited installation space, these bearings offer high load capacity, reduced friction, enhanced rigidity, long service life, and simple mounting. The induction hardened raceways and precision rolling elements provide low wear and improved durability, making them ideal for demanding industrial machinery requiring reliable and precise rotational support.
