The main body of the ball bearing is made of galvanised carbon steel, which has the properties of scratch resistance, corrosion resistance and rust resistance and is not easy to damage. With a rubber sealing ring that prevents dust from entering, it is suitable for harsh working environments. The KFL08 bearing has built-in balls that improve the load capacity of the bearing seat. The inner ring of the bearing is equipped with a locking screw that allows the shaft and the bearing to be locked. The bearing kit can be installed directly on the mechanical device via multiple screws, has the function of self-alignment and can be easily adjusted or replaced to improve work efficiency.
