💡 What is a 4-bolt flange mounted bearing used for? Short answer: It supports and locates rotating shafts and makes installation and maintenance handy. - Provides stable shaft support for conveyors, pumps, motors and gearboxes using a sealed ball bearing insert for contamination resistance. - Speeds maintenance with an insert-style sealed ball bearing and relubrication port (1/8-27 NPT) for long service life. - Great where a secure flange mount and heavy-duty set-screw locking are required, including linear slide unit setups and industrial machinery bases.
