Linear bearings, sometimes called track runner bearings, are part of a system suitable for use in precision linear motion applications, such as in printing machines and computer numerical control (CNC) equipment. Other system components include glide shafts, support rails, and glide blocks.A mounted linear bearing from Grainger, such as a linear pillow block bearing or flange bearing, can offset torsional misalignment and provide extra support. Choose linear motion bearings from single-flange and double-flange options. These bearings feature numerous holes that can allow you to add many accessories and brakes.


Linear Ball Bearings are designed to provide a free motion in one direction. These are the most common type of linear slide, offering a smooth precision motion along a single axis linear design. Most commonly used within the furniture industry as a ball bearing drawer slide.
