2 Pack 20mm SBR20LUU Bearing Blocks For Linear Rails And Shaft Guides Heavy Duty Aluminum Open Long Sliding Ball Bearing Blocks With Pressure Plate Locking For High Precision CNC Builds

2-Pack 20mm SBR20LUU Aluminum Linear Bearing Blocks for CNC
✔️ 2x long open blocks, 20mm rail fit, pressure plate lock

These are heavy-duty aluminum open long sliding bearing blocks designed for 20mm linear rails (SBR20LUU). They pair with 20mm shaft guides in CNC machines, automation setups, or DIY linear motion projects for smooth, precise movement.

✅ 20 mm (0.79 in) rail compatibility with SBR20LUU blocks
✅ Aluminum alloy body with bearing steel insert for durability
✅ Pressure plate locking for stable ball retention and smooth operation
✅ M6 x 12 mm mounting holes for quick assembly
✅ 2-pack set includes 2 blocks for paired track alignment
✅ 20 mm rail and shaft compatibility for CNC builds

💡 What is a 20mm linear bearing block used for in CNC setups? This handy component keeps motion straight and accurate across running rails. - 20mm blocks provide precise carriage support on 20mm rails - They reduce lateral play and vibration in automated machines - Ideal for CNC routers, 3D printers, laser cutters, and automation rigs - Works with SBR rails for smooth, reliable linear motion
