Featuring a quick-release M3 clamp bolt and compact dimensions (42x14x33mm), it ensures secure, low-friction support for linear rails in 3D printers, CNC machines, and other precision industrial equipment. Sold as a set of two, it offers easy installation and maintenance, enhancing machine accuracy and durability. ## Description Usable with any 8mm linear guide, you can simply slide the rail through, then tighten the clamp screw at the top to fix it in place. Then use up to 6mm diameter bolts to attach them. If you need to disassemble or otherwise repair your robot or machine, its easy to open up the clamp and remove the rail. Unlike shaft support rails, blocks do not permit longitudinal passage of open-type ball bushing bearings. Shaft support blocks enable clamping of shafts. Linear bearing widely used in electronic equipment, tension tester and digital 3d coordinate measurement equipment and other precision equipment and multi-axis machine, punch, tool grinding machine, automatic cutting machine, printer, card sorting machine, installed the sliding parts such as industrial machinery. Has good performances, low friction coefficients and long usage spans.
