KP08 8MM PILLOW BLOCK MOUNTED BEARING

The KP08 Pillow Block Mounted Bearing is a versatile, robust bearing assembly designed to support rotating shafts in a wide range of mechanical applications. It combines a sealed ball bearing with a sturdy zinc alloy pillow block housing, providing a ready-to-mount solution that simplifies machine design and assembly.

The bearing features an 8 mm inner diameter, perfectly suited for standard 8 mm linear shafts, T8 lead screws, and M8 threaded rods, making it an excellent choice for 3D printer Z-axis assemblies, CNC linear motion stages, and DIY automation projects. The outer housing is precision-cast and finished in a durable gray-black coating that resists corrosion and wear.

The pillow block design features two mounting holes spaced 42 mm apart (center to center), with a 7 mm hole diameter that accepts M6 mounting bolts for secure installation. The low-profile 55 × 13 × 28 mm footprint allows the KP08 to fit into tight spaces while still providing the rigidity required for stable, vibration-free rotation.

Pillow block bearings of this type are widely used across many industries — including food processing machinery, pharmaceutical equipment, conveying systems, film processing, spinning machines, and printing machinery — thanks to their ease of installation, self-aligning capability, and reliable performance under continuous operation. The sealed bearing element protects internal components from dust, debris, and moisture, extending service life and reducing maintenance.

For most installations, two KP08 units are used in pairs — one at each end of a shaft or lead screw — to provide stable, evenly-supported rotation. The self-aligning ball bearing inside the housing tolerates minor shaft misalignment, making installation forgiving and ensuring smooth operation even in DIY builds.
