Twin Linear Ball Bearing Pillow Block IPPSW08G 1/2″ Closed - Self Aligning Precision Plus
Double-size ball bearing pillow block, closed shell, with 1/2" bore, using a self-aligning bearing inside an aluminum alloy housing. The double-length bearing is roughly equal to two standard bearings mounted end to end. Self-aligning ball tracks accommodate minor misalignment, and two side-mounted grease zerk fittings provide lubrication access. Heat-treated alloy steel, recirculating hardened steel balls, and a resin retainer cage support smooth, low-friction, low-noise motion. Double seals are standard, and the bearing is well suited to cantilevered loads because it is not subject to the same 2:1 binding limitation as plain bearings.
