Barden Bearings PBO-8 Linear Motion Block Bearing

Barden Bearings PBO-8 Linear Motion Block Bearing is an open, 1-inch bore pillow-block housing built to accept a ball bushing for smooth, low-friction linear motion along a round shaft. The PBO-8OPN variant (open type) is designed for easy installation and alignment in compact linear-motion assemblies, offering self-aligning capability and adjustable preload to suit varying mounting tolerances. It is lubricated with a linear lubricant and features integral seals at both ends to help retain lubricant and protect against contaminants, extending service intervals in demanding environments. This block is routinely used in CNC slides, automated assembly lines, and other machinery requiring precise, repeatable shaft guidance, delivering accurate radial and axial guidance while minimizing backlash when paired with compatible PBO ball bushings and 1" shafts.
