Barden PBO-8 Precision Linear Block Bearing Assembly

The Barden PBO-8 Precision Linear Block Bearing Assembly is a pillow-block open housing designed for a 1/2-inch round shaft, delivering precise, smooth linear motion in compact automation and machine-tool axes. It uses a single PB Series precision steel ball bearing inside a 2.000 inch outside-diameter block with a 2.000 inch overall length, designed specifically for a 0.5 inch shaft bore. This open-type pillow block provides straightforward installation along a round-shaft axis and is commonly used in CNC slides, automation stations, and robotics where reliable, repeatable axial guidance is required. The PBO-8 name identifies this model within the open-block family (often listed as PBO8OPN) and reflects its role as the single-bearing, open pillow block option for a 1/2-inch shaft in round-shaft linear guide assemblies. Catalogs and suppliers frequently reference the PBO-8 in the context of RoundRail/open pillow-block configurations, underscoring its suitability for compact, high-precision motion paths.
