Catalog excerpts
On each backing shaft of a multi-roll mill, several bearings are installed side by side. With their outside diameter surfaces in direct contact with the intermediate rolls, these bearings rotate while carrying components of rolling force. Therefore, the outer rings of these bearings are required to have adequate rigidity and fatigue strength, and should be finished with high precision. The outside diameter surfaces of these bearings are crowned, preventing load concentration at the ends and thus protecting the intermediate rolls from damage. > Crowned outside surfaceUncrowned outside...
Open the catalog to page 3The outside diameter surfaces of the bearings used on the backing shafts of multi-roll mills should be ground periodically to retain precise bearing performance, thus ensuring the quality of rolled products. JTEKT supplies the jigs that grind bearing's outside diameter surface with high precision. Once the bearing is installed into the jig, the jig completely nullifies any clearance on the fitting surface between the jig and bearing and the internal clearance of the bearing, eliminating play in the radial direction.The jig grinds the outside diameter surface while turning the outer ring and...

JTEKT supplies Measurement for bearing section height that suit the individual bearings listed on the dimensional table. > 1 1 These bearing section height measurements are highlyrigid and perform extremely precise measurement.These measurements can measure the runningaccuracy of the outer rings as well.For easy bearing installation...
