Linear Ball Bearing Pillow Blocks

Linear Ball Bearing Pillow Blocks featuring an aluminum alloy housing encasing a linear ball bearing with a heat-treated alloy steel shell for durability. Available in single or twin sizes (twin featuring two standard blocks back-to-back), they come in open shells for rail-supported shafts or closed shells for full shaft stability. Resin retainer polymer cages with multiple precision steel balls ensure quiet operation, low friction, and speed. Offered in inch (1/4" to 2") and metric (8mm to 50mm) sizes, they are size-interchangeable with industry standards and PBC’s Simplicity® plain linear bearings. Double seals, included as standard at no extra cost, protect against contaminants to extend bearing life. Compatible with press-fit or slip-fit installation using epoxy, select variants feature a self-aligning crowned bearing shell and a grease zerk fitting for easy lubrication.
