Product Description


Linear bearing is a kind of linear motion system for straight cylindrical shaft with the use of travel and. Because the bearing ball and bearing point contact ball with minimum friction rolling, so linear bearing with small friction, and relatively stable, does not change with bearing speed, can obtain a smooth linear motion with high sensitivity and high precision. Linear bearing consumption has its limitations, the most important is the impact load bearing ability is poor, and the bearing capacity is poor, then the linear bearing vibration in high-speed motion and large noise. Fast and easy and automatic selection of linear bearings have included. The sliding parts of linear bearings are widely used in precision machine tools, textile machinery, food packaging machinery, printing machinery and other industrial machinery.

The ball bearing contact with the bearing point, so the use of small load. The ball rotation to low friction resistance, stable motion can be obtained with high accuracy.

Plastic linear bearing is a kind of self lubricating characteristics of linear motion system, the biggest difference is that the metal and metal linear bearings, linear bearings are rolling friction between the bearing and the cylinder axis is point contact, so it is suitable for low load and high speed motion; linear bearing is plastic sliding friction


Type of bearing

1) standard, clearance adjustable linear bearings, linear bearings, open type lengthened linear bearings, universal linear bearing

(2) flange type linear bearings can be divided into: the method oriented round flange type, method type, blue oval flange, flange type, round type guide, guide Blue Oval flange, extended round flange type.



Linear bearing is used in conjunction with the quenching line transmission shaft. A system of infinite linear motion. Load ball and quenching shaft because it is the point of contact, allowing the load, but the linear motion, minimum friction, high precision, fast motion.




Linear bearing adjustment type, open type bearing, outer diameter cut before the measurement, there will be some elastic deformation after cutting, with the clearance to be measured into the bearing seat (steel bearing, KH bearings to maintain a similar situation). Clearance adjustable bearing seat and the bearing should adjust the direction perpendicular to the direction of cutting to ensure uniform clearance, linear bearing structure cannot rotate, have good guidance at the same time, so the linear bearing generally two axis + four sets of bearings or shaft two + two sets of lengthened bearings using a combination of two, shaft installation must be straight, the whole assembly, hand push pull must be flexible and no block to the installation of transmission mechanism, transmission power is enough to overcome the friction friction bearings, linear bearings approximately 1/1000 working load.
