Heavy Duty 20mm SBR20UU Bearing Blocks 2 Pack Open Sliding Ball Bearing Blocks For SBR20 Linear Motion Shafts Guides And CNC Linear Rails Kit Aluminum Alloy With Pressure Plate For Precise Smooth Sliding
✔️ 2-pack aluminum alloy SBR20UU with pressure plate for stability
These are 20mm SBR20UU ball bearing sliding blocks designed for linear motion on 20mm (0.79 inch) shafts. Constructed from aluminum alloy with bearing steel internals, they’re built for heavy-duty CNC rigs, automation lines, and precise, quiet movement. They pair with SBR20 rails to form an economical linear guiding system used in DIY CNC, printers, and automation projects.
✅ 2 pcs SBR20UU block set✅ Aluminum alloy housing with built-in bearing steel balls
✅ M6 x 12mm mounting holes for easy attachment
✅ Pressure plate upgrade for stable ball lock and longer life
✅ Fits 20mm linear rails (SBR20) for smooth, silent sliding
💡 What is a pillow block bearing used for in CNC linear motion systems? Pillow blocks support shafts and internal bearings to keep alignment and reduce wobble in linear guides. - Handy for 20mm shaft support in automation and CNC - Helps maintain precise alignment for smooth motion on SBR-20 rails - Easy to mount with standard mounting holes and common hardware - Reduces maintenance and wear in robotic or machine setups
