With the right accessories, a linear motion system can be drastically improved so that it is easily assembled and safe & easy to use. Raptor Supplies offers a wide range of these accessories, such as acme flanges, nuts & screws, linear guide rails, shafts & carriages, mounted & unmounted linear bearings from NB, Duff-Norton, Apollo, Warner Linear and Thomson. While the mounted linear bearings are used for correcting torsional misalignments and providing additional support for sliding doors, 3D printers & automated devices; the unmounted linear bearings support linear motion shafts. The latter feature outer sleeves for delivering a quiet, smooth & low-friction linear motion. We also offer mechanical actuators for linear positioning in machine tools, robots and electromechanical actuators installed in fan louvres, film processing equipment & lift tables demanding high-stroke speeds.
