CSB-LIN® plastic linear bearings are engineering plastic linear sliding bearings. It is composed of two parts: One is the inner liner which is made of optimized high-performance engineering plastics, and the other is the outer shell which is a magnesium-aluminum alloy with anodized hard surface treatment.About working principle. It is the sliding friction between the bearing and shaft for the plastic linear bearings and rolling friction for metal ball linear bearings. About the perspective of maintenance, plastic linear bearings can be permanently maintenance-free, while traditional metal rolling bearings it needs the help from lubricants to operate normally, because it is metal-to-metal contact among the ball, cage and the dual shaft, that is it needs frequent maintenance. About the bearing capacity, it is face-to-face contact between the engineering plastic linear bearing and the dual shaft and it is point-line contact between the metal ball linear bearing and the dual shaft, lead to the load capacity of the plastic linear bearing is greater than the metal ball linear bearing.About the linear motion performance, the sliding friction of the engineering plastic linear bearing and the rolling friction of the metal ball linear bearing make the allowed linear velocity of the former one is lower than the latter one, and the noise of the plastic linear bearing is much lower than the metal ball linear bearings. About the ability of anti-corrosion, it is very obvious: the corrosion resistance of engineering plastic linear bearings is much better than metal ball linear bearings.
