Industrial 1629-220-21 Linear Rail With Bearings

The 1629-220-21 Linear Rail with Bearings delivers precise, low-friction guided motion on a 24-inch rail designed for medium-stroke industrial automation tasks. It supports accurate linear travel and repeatable positioning in CNC machines, packaging equipment, automated assembly systems, material handling gear, and production machinery requiring reliable guidance. The system uses a surface-mount rail with a recirculating ball bearing carriage and a hardened, ground steel rail paired with bearing-grade steel and recirculating ball elements, lubricated by a grease-based system for long service life. This OEM replacement component is typically used for rail replacement, machine retrofits, motion-system repairs, and routine maintenance by OEMs and integrators. It provides multi-directional load support and smooth travel characteristics essential for robotics, pick-and-place, inspection stations, and other automated equipment where high repeatability matters. The rail’s industrial finish offers wear resistance, and compatibility notes indicate suitability for CNC, robotics, and automated equipment applications; common replacements include Bosch Rexroth STAR Linear Rail Assembly, THK Linear Guide Rail Assembly, and NSK Linear Guide Rail Assembly.
