Simplicity Bearings, taking care of your toughest jobs
PBC Linear combines a standard Simplicity® Linear Plain Bearing with a self-aligning housing to create our self-lubricating Linear Pillow Block. The standard offering consists of an aluminum outer shell with FrelonGOLD® bearing liner, but stainless-steel housings and Frelon® J and Frelon® W liners are also options. The Pillow Block is vibration dampening and is well suited for a wide temperature range of -400°F/ 400°F (-240°C/ 204°C). Machined to tighter tolerances than industry standards, PBC Linear Pillow Blocks offer better accuracy in your linear motion applications.

Simplicity linear bearings can operate in any orientation. Load capacities will vary on open bearings depending on the orientation in which they are being used.
Standard pillow blocks have 1/2° misalignment from the centerline. This feature is built into the housing with a spherical radius at the midpoint of the block. The self-aligning capability allows for some shaft deflection and misalignment.
Rigid or straight bore housings, which are typically used in single shaft applications, are also available. This does not allow for any self-alignment and provides a very rigid assembly.
This is the Imperial (Inch), closed, single length version of the linear pillow block. The closed bearing design allows for a lower cost installation by using end supported shafts.

This is the Imperial (Inch), closed, single length version of the linear pillow block, with the addition of a compensated running clearance. The closed linear bearing design allows for a lower cost installation by using end supported shafts. The compensated running clearance creates extra space in the inner diameter, allowing the linear pillow block to function like a linear ball bearing, making it perfect for parallel shaft applications.
