Linear Bearings

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.
