💡 What is a pillow block bearing used for in high-temperature machinery?
A pillow block supports and secures a rotating shaft while keeping a sealed ball bearing aligned under heat and load.
- Supports shafts on conveyors, fans, pumps, and industrial drives; works with sealed ball bearing and linear slide unit setups for smooth operation.
- Suited for high-temp environments (up to 450°F) when you need relubricatable inserts and reliable silicone contact seals.
- Steel ball inserts with C4 clearance handle radial loads and slight misalignment; ceramic inserts are an alternative when extreme heat or corrosion resistance is required.
