The VEVOR Linear Guide Rail Set is an essential component for engineers, CNC hobbyists, and DIY fabricators looking to upgrade their automated machinery with high-precision motion systems. This set provides smooth, stutter-free movement through two 1200 mm SFC20 guide rails and four SC20 slide blocks, ensuring reliable performance under heavy loads. While the system offers exceptional durability and industrial-grade construction, users should note that the 1200 mm length requires a sturdy, perfectly aligned mounting surface to prevent binding or long-term structural deflection.

Yes, but you will need metal-cutting tools such as an angle grinder or a chop saw. Ensure you chamfer the cut ends so the slide blocks can be re-installed without damaging the bearings.
These blocks are designed specifically for SFC20 rails. While other 20 mm rails may have similar dimensions, we recommend using the provided set to ensure tolerance compatibility.
The speed is generally limited by the type of drive system (e.g., lead screw, belt, or rack and pinion) attached to the carriage, rather than the rails themselves.
They are shipped with a factory protective coating, but it is highly recommended to apply a fresh layer of machine lubricant before initial use.
Yes, the load ratings provided are for dynamic movement, and they can be used in vertical Z-axis applications if the driving motor can handle the load and braking.
Check the parallelism of the two rails. If they are not perfectly parallel, loosen the rail supports and realign the system.
Clean the rails of any grit or metallic particles and apply a high-quality machine lubricant to the shaft.
Add additional support brackets or ensure that the mounting surface is rigid enough to support the 1200 mm length without sagging.
To ensure optimal performance, start by verifying that your mounting surface is perfectly level across the full 1200 mm span. Use a precision level or an alignment jig to space the two rails parallel to one another.
