Linear Ball Bearing Pillow Blocks
Browse Categories
Linear Ball Bearing Pillow Blocks feature an aluminum alloy housing with a bearing inside. Available in single or twin sizes (twin equating to two standard blocks back-to-back), they offer open bearing shells for rail-supported shafts, closed shells for full shaft stability and adjustable variants with an open slit down the side of the bearing. The ball bearings, paired with a heat-treated alloy steel shell, deliver a low coefficient of friction for smooth operation, while resin retainers (polymer cages) enhance efficiency and reduce noise. Available in inch (1/4" to 2") and metric (8mm to 50mm) sizes, they are interchangeable with industry standards and our Simplicity plain linear bearing series. Double seals, included as standard at no additional cost, protect against contaminants, extending bearing life. They are compatible with press-fit or slip-fit installation using epoxy. Select variants are self-aligning with a crowned bearing shell inside the housing and include a grease zerk fitting (lubrication port) on the side for easy maintenance.
