RV Reduction Gear Bearings - thin section angular contact ball bearing

BRSZC specialized in thin section angular contact ball bearings for RV reduction gears. RV reduction gear main bearings increases reliabilty, reduces overall cost, increases moment rigidity and maximum allowable moment. Reduces the number of components required. Simplifies installation and maintenance.

Thin section angular ball bearings are used as the main bearings with RV-E Series reduction gears. Assembly's accuracy, especially bearings' accuracy, is very important for RV-E reduction gears to get optimum performance.
