Twin Linear Ball Bearing Pillow Block IPPW04G 1/4″ Closed

Linear ball bearing pillow block with two inserted 1/4" ID closed-shelled standard-size bearings mounted back to back inside a double aluminum alloy housing. The twin configuration increases the bearing span for greater load support and stability. Heat-treated alloy steel bearing shells, recirculating hardened steel balls, and resin retainers provide durable, low-friction motion with reduced operating noise. Linear ball bearings are well suited to cantilevered, overhung, and offset-load applications because they handle off-center forces without the same 2:1 binding limitation that applies to plain bearings. Double seals are delivered at no extra cost.
