In use as a gantry for large router to flatten natural wooden boards. Really smooth running. Review: Very accurate addition to any CNC machinery - As a builder and enthusiast of automated machinery, I rely on the precision and durability of every component. The CNCMANS SBR20-1000mm linear guide set exceeded all my expectations. This kit is an absolute powerhouse, offering industrial-grade performance at an incredible value, and it has elevated the performance of my equipment to a new level. Robust build and flawless operation The first thing you notice is the superior construction. The SBR20 stainless steel linear rails are incredibly sturdy and have a high-quality surface finish, ensuring smooth and uninterrupted travel for the bearing blocks. The four SBR20UU bearing blocks glide along the rail with minimal friction and noise. The motion is whisper-quiet and incredibly fluid, providing the kind of precision that is essential for accurate CNC work. There is zero play or wobble, which translates directly into cleaner cuts and more accurate parts. Easy and reliable installation Installation was a breeze, thanks to the pre-drilled holes in the aluminum alloy support rails. The kit arrived with everything needed, making for a straightforward setup right out of the box. Once mounted, the system provided an immediate and noticeable improvement in the machine's stability and rigidity. The precision of the machining ensures perfect alignment, saving time and frustration during assembly. The perfect upgrade for any CNC project Whether you're building a new CNC router, a 3D printer, or upgrading existing automation equipment, this linear guide kit is a brilliant investment. It delivers a level of performance that rivals much more expensive options on the market. The high dynamic and static load capacities give me the confidence to push my machines harder and faster, knowing the motion system is built to handle it. This is an essential component for any serious builder who demands both high quality and exceptional value from their parts. ## Features - This linear rail set contains 2pcs 1200mm long rail shafts and 4pcs SBR20UU blocks.
