💡 What is a 3-bolt flange bearing used for in industrial machinery? A 3-bolt flange bearing supports and locates a rotating shaft at fixed mounting points while offering sealed ball bearing protection and easy greasing. Handy for light to medium duty shafts and common shop equipment. - Supports radial loads with sealed ball bearing options for dust and debris protection - Mounts quickly to panels and housings for conveyors, fans, pumps, and linear slide unit applications - Allows relubrication via 1/8-27 NPT fitting and can be specified with ceramic ball options for corrosive environments - Set-screw locking and a wide inner ring improve shaft grip and alignment during operation
