15mm Diameter Linear Bearing Pillow Block

15mm Diameter Linear Bearing Pillow Block

Discontinued

A sliding ball-bearing platform designed for 15 mm T-shaped supported slide rails, commonly used in CNC machines, robotics, and linear motion projects. The pillow block features a plastic interior with circulating ball bearings for smooth, low-friction travel along the rail.

The 60 × 35 mm platform has four M4 tapped mounting holes for attaching custom platforms, tool holders, or other components. The T-shaped rail profile prevents the bearing from detaching once installed, and provides sufficient support for loads up to approximately 2.3 kg (~5 lb) on a single rail. For heavier loads or wider platforms, use two parallel rails.

Warning: Do not attempt to attach the pillow block to the rail without the plastic insert in place. The insert retains the ball bearings during installation. Refer to the product photos for the correct assembly procedure.
