Product Description

PRODUCT DETAILS

Spherical roller bearings are the "stabilizer" for mechanical operation, and their double row drum shaped rollers and spherical raceways are precisely matched to automatically compensate for shaft misalignment errors, ensuring stable operation even under complex working conditions. The bearings are made of high-purity steel with vacuum degassing, processed by advanced quenching and tempering technology, achieving a perfect balance between hardness and toughness, effectively improving fatigue life and impact resistance. By optimizing the contact geometry design between the roller and the raceway, not only has the operating noise and vibration been reduced, but the lubrication efficiency has also been significantly improved, reducing friction losses. In the rotating support system of large port cranes and the high-speed operation of paper machinery drying cylinder devices, spherical roller bearings ensure efficient operation of equipment with excellent comprehensive performance, providing solid support for the continuity and reliability of industrial production.
