12mm Long Square Flanged Bushing Linear Motion

12mm Square Flanged Bushing Linear Motion Guide Unit For CNC
✔️ 12mm ID 21mm OD 57mm Flanged Bushing Has Static and Dynamic Load

This LBK12LUU bushing slides smoothly on shafts. It works well in printers, routers and machine tools needing linear motion control.

✅ Inner diameter measures 12 mm exactly
✅ Outer size is 21 mm wide for stability
✅ Overall length runs 57 mm for longer stroke support
✅ Rated dynamic load takes 813 Newtons of force
✅ Rated static load holds up to 1570 Newtons tight

💡 Why do engineers prefer sealed bushings over plain liners in CNC gear?

- Seals prevent dust from entering the raceway area entirely. - Low friction allows smoother movement without extra lubrication. - Maintenance drops significantly so operators save time and money.
