💡 What is a 4-bolt flange bearing used for in conveyor, agricultural, and light manufacturing systems?

A 4-bolt flange bearing is a handy mounting solution that secures a rotating shaft to flat surfaces while protecting the sealed ball bearing insert from contamination.

- Ideal for supporting shafts in conveyor frames, idler rolls, and gearbox output shafts; sealed ball bearing keeps contaminants out - Handy alternative to a pillow block bearing when space or face-mounting is required; works well with linear slide unit setups and shaft guides - Low-maintenance choice when paired with a relubrication port (1/8-27 NPT) to extend service life and reduce downtime
