Linear Bearing is a kind of linear motion system produced based on low cost. It makes linear reciprocating displacement on a matching cylindrical shaft. This bearing consists of a sleeveed outer ring.multi-row balls and a retainer. The balls are point-contacted with the shaft and run under tiny friction, so that the bearing have long running life and easy maintenance and replacement. The more the ball rows are,the less the friction force is.
It is widely used in the textile machinery, the printing mechanism, the power tool, the medicine mechanical, the precision machine tool, the electrical cutting, the self-recording instrument and the office equiment etc.
