The VEVOR Linear Guide Rail Set is an essential component for engineers, CNC hobbyists, and automation professionals looking to build reliable, high-precision motion systems. This kit provides a complete foundation for stable linear movement, featuring a 20 mm shaft diameter and robust load-bearing capacities. While it offers excellent performance for demanding DIY and industrial applications, users should note that precise alignment during initial installation is critical to avoid binding or uneven movement.

Each rail is 1000 mm long, which is approximately 39.4 inches.
Yes, the kit includes 4 SC20 slide blocks along with the rails and supports.
Yes, you can cut the steel rails to a custom length using a metal-cutting saw, though care must be taken to maintain a clean edge for smooth bearing movement.
Each slide block is rated for a dynamic load of 882 N and a static load of 1370 N.
Yes, the included rail supports are designed to mount the rails securely to your base surface.
It is highly capable for DIY and mid-range CNC applications, though extremely heavy industrial milling may require larger, proprietary systems.
Clean the rail surface thoroughly and inspect for debris. Ensure the blocks are properly lubricated and not overtightened on the supports.
Check that the rails are perfectly parallel. Use a caliper to measure the distance between rails at multiple points along the 1000 mm length.
Verify that all mounting bolts are secure and that the slide blocks are adequately lubricated with a compatible lubricant.
Installation requires a flat, level mounting surface to prevent twisting the rails. Begin by securing the rail supports at even intervals along your frame, ensuring the distance between them matches the rail length. Once the rails are placed, tighten the fasteners gradually rather than fully at once to allow for minor adjustments. Use a precision level or dial indicator to ensure the two rails are perfectly parallel before final tightening.
For maintenance, keep the rails free of dust and debris, as these can score the surface and hinder smooth block movement. Periodically apply a light machine oil or high-quality lithium grease to the slide blocks to maintain low friction. Avoid using harsh solvents that could strip the factory protective coating.
