3-Bolt Flange Housings

3-bolt flange housings provide a compact, triangular mounting footprint for ball bearing inserts where space is tight and a square 4-bolt pattern won’t fit. Off Road Belts stocks cast 3-bolt flange units sized to accept standard set-screw and eccentric-lock bearing inserts, making them ideal for conveyors, agricultural implements, and general industrial machinery. Pair a housing with the matching insert to build a complete mounted bearing assembly, or replace a worn housing to extend the life of your existing equipment.
