Backing Bearings | Sendzimir Z-Mill Cylindrical Roller Bearings

Our Backing Bearings are specially engineered as backing bearing for rolling mill applications, particularly for Sendzimir mill bearings used in multi-roll Z-mill cold rolling machines. Designed as double row and triple row cylindrical roller bearings, they feature an extra thick outer ring that functions as the working surface, while the inner ring remains stationary on the mandrel, ensuring exceptional rigidity, stability, and long service life under extreme operating conditions.

These backing bearings are dimensionally interchangeable with leading international brands, including SKF BCZ series, NSK 2U series, and FAG Z series. We also provide NNCF series replacement solutions and custom BN series models to meet specific application requirements. With high precision P4/P2 tolerance grades and strict T-value matching, our products ensure consistent performance and reliable full-set assembly in demanding rolling mill environments.

Widely used in steel processing and metallurgical industries, our backing bearings are a cost-effective alternative to imported original bearings. Whether for equipment upgrade, maintenance, or replacement, they deliver the same dimensional compatibility and performance while helping reduce procurement costs and lead times.
