Mophorn Linear Rail 2PCS 500mm SBR16 Linear Slide Rail 4PCS SBR16UU Bearing Block CNC Kit Linear Rails and Bearings Kit CNC Rails Linear Rail Set for CNC Machines

500mm SBR16 linear rail: This linear guide set consists of 2 pieces of SBR16 rail shafts with a length of 500 mm and 4 SBR16UU blocks. Sliding blocks are intended to be used in conjunction with the rails. Internal linear guide ensures smooth gliding. High quality steel material: ball screw are made of carbon steel, linear guides are made of GCr15 bearing steel with aluminum alloy housing. Surface chrome plating has rust protection. The hardness can be as high as HRC62, more durable. First-class linear guide system: Perfect combination of main axle bearing rail and aluminum alloy, which nicely stabilizes the original rail. Industry standard SBR block with high-precision linear guide inside. Easy Installation: Aluminum alloy linear guide rail with pre-drilled holes for easy assembly. Stainless steel linear rail for linear movement. Easy to install, maintenance free. Wide application: The ball screw set is widely used in automation machines such as DIY CNC milling machines, lathes, machine tools, bending machines, laser welding machines, etc. Also suitable for large gear equipment such as industrial robots and cracker machines.
