💡 What is a sealed ball bearing insert used for in high-temperature flange housings? Sealed ball bearing inserts support rotating shafts in flange housings where heat, dust, or washdown demand a sealed, relubricatable unit. A handy solution for maintenance and uptime. - Provides shaft support and radial and axial load handling for conveyor systems, oven lines, and kiln equipment. - Silicone contact seals and slinger protect grease and keep contaminants out for longer service life. - C4 clearance and 400°F (204°C) rating let the bearing handle thermal expansion in hot setups. - Fits common 4-bolt flange housings and serves as a direct replacement without changing the housing.
