Understanding linear bearings

　　Linear bearing is used in precision machine tools, textile, food packaging, printing and other industrial mechanical sliding parts, is a kind of linear motion system.Linear bearing friction is small, the advantages of stable, will not change with the bearing speed, high sensitivity, high precision, while the linear bearing which so many advantages, but there are always two sides to everything, disadvantages as well as linear bearing, bearing impact load ability is poorer, carrying capacity is also poor, linear bearing in high speed motion vibration and noise is bigger also.

　　Linear bearing structure is the ball and raceway, each race inside there is a ball loop back bead tank, so as to form a closed circuit with circulate ball movement.Linear bearing according to the basic structure of different form, can be divided into three types: standard linear bearing, linear bearing and open mouth linear bearing clearance.

　　The characteristics of the different structure form, the corresponding diameter is not the same.Standard linear bearing, installation is simple, convenient, has a wide application scope;Linear bearing clearance type, after adjustment for a very small radial clearance, which has high radial work progress;Open mouth linear bearing, can make the light structure, compact and cost savings.
