💡 What is a 4-bolt flange mounted sealed ball bearing used for? They hold and support rotating shafts in a compact, heat-tolerant flange mount and keep contaminants out while allowing relubrication. - Ideal for mounting shafts on conveyors, oven equipment, and compact pillow block or linear slide unit replacements - Provides sealed ball bearing performance with silicone contact seals for dust and splash protection - C4 clearance and bearing steel insert work with relubrication and set-screw locking; ceramic ball options are common for extreme heat or corrosion
