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.
