What is lm linear bearing?

1. Introduction to lm linear bearing

lm linear bearing is a component in which rolling friction replaces sliding friction. It consists of an outer ring, steel balls, cages and retaining rings. There are several (not less than 3) longitudinal tracks on the inner wall of the outer ring. The steel balls are between the outer ring and the guide shaft. Rolling along the groove of the cage.

2. Characteristics of lm linear bearing

1. LM linear bearing is a low-cost linear motion system for use with infinite stroke and cylindrical shafts.

2. Since the load-bearing ball is in point contact with the shaft, the operating load is small. The steel ball rotates with minimal frictional resistance, resulting in smooth motion with high precision.

3. The lm linear bearing is an integral sleeve that can only bear radial loads and perform linear reciprocating motion. The radial clearance is divided into adjustable and non-adjustable types.

4. It can be made into ordinary grade (P) and precision grade (J) precision.

3. Application of lm linear bearing
lm linear bearings are widely used in precision equipment such as electronic equipment, tensile testing machines, and digital three-dimensional coordinate measuring equipment, as well as industrial machinery such as multi-axis machine tools, punch machines, tool grinders, automatic cutting machines, printers, card sorters, and food packaging machines. sliding parts.

4. The influence of temperature on the life of lm linear bearing
When the operating temperature of lm linear bearing exceeds 120°C, the bearing parts will lose their original dimensional stability. Therefore, for bearings with operating temperatures higher than 120°C, special requirements can be made to HRB Company and bearings with special heat treatment can be selected.
