Twin Linear Ball Bearing Pillow Block IPPSW12G 3/4″ Closed - Self Aligning Precision Plus
Twin linear ball bearing pillow block, closed-shelled, with two 3/4" Precision Plus® self-aligning bearings mounted back to back inside an aluminum alloy housing. The self-aligning design uses floating internal raceway elements that can shift slightly to accommodate minor shaft and housing misalignment while maintaining smooth rolling contact. Linear ball bearings are especially well suited to cantilevered and overhung-load applications because they can tolerate offset drive forces without the same 2:1 binding limitation that applies to plain linear bearings. Two grease zerk fittings provide convenient lubrication access. Heat-treated alloy steel bearing components, recirculating hardened steel balls, and resin retainers support smooth, low-friction motion with reduced operating noise. Double seals are delivered at no extra cost.
