1、With high hardness, bearing block keeps low noise, which can be anti-rust and anti-corrosion. 2、Adopts aluminum alloy material, CNC block can support simple installation through bolts. 3、Meanwhile, linear bearings have been configured inside, linear bearings are used in conjunction with hardness linear transmission shaft. 4、Since the ball and the motion transmission shaft are in contact, the load is small and the allowable load is small. 5、Entitled with practical adoptability, bearing block's high quality can keep its high performance for a long time. 1 x Bearing Block Item Type: Bearing blockModel: scs50uuMaterial: Aluminum alloyShaft Diameter: Approx. 50mm / 1.97inStructure: Shell + linear bearing
