This SBR12 linear guide rail set comes with two 800mm rails and four carriage blocks to support smooth motion in workshop builds and automated machines.

✅ Two 800mm SBR12 rails made from carbon steel with chrome plating for rust resistance
✅ Four ball bearing sliders with adjustable tension handles for custom fit
✅ Includes four locking handles and locators for secure positioning
✅ Pre drilled rail supports allow fast mounting on flat surfaces
✅ Handles up to 2200lbs load for heavy duty linear movement tasks

💡 What factors determine smooth performance in a linear motion guide rail system? A well designed linear rail system keeps motion precise and quiet under load. - Ball bearings inside each slider reduce friction and support consistent travel along the full rail length - Adjustable tension handles let users fine tune slider tightness for different project needs - Carbon steel rails with chrome plating resist wear in workshop or automation setups - Pre drilled holes on the rail supports speed up installation on tables or machine frames
