Bosch Rexroth AG R021M80612 Linear Guide Rail

Bosch Rexroth AG R021M80612 Linear Guide Rail is a 19-inch long precision linear guide rail designed for mounting in automated machinery and robotics to provide smooth, controlled linear motion. As part of Bosch Rexroth's linear motion technology, it typically works with a compatible ball runner block to form a complete rail-and-carriage system that supports accurate positioning and low-friction travel along a straight axis. The R021M80612 model designation exactly identifies this rail length and mounting pattern, enabling engineers to pair it with the correct carriage, mounting hardware, and alignment tolerances for reliable operation. Common applications include CNC machines, automated assembly lines, packaging equipment, and other industrial automation scenarios where repeatable, guided motion is essential.
