Linear Bearing with Balls Slide block bushing

14 Published by admin Jun 21,2024

Linear bearing with balls is a linear motion system used in conjunction with cylindrical shafts for linear travel. Due to the contact between the bearing ball and the outer shell of the bearing, the steel ball rolls with the minimum frictional resistance, resulting in low friction and relatively stable linear bearings that do not change with the bearing speed. This allows for high sensitivity and precision in achieving smooth linear motion.
Linear bearing with balls are widely used as sliding components in industrial machinery such as precision machine tools, textile machinery, food packaging machinery, printing machinery, etc.
Due to the contact between the bearing ball and the bearing point, the load is small. The steel ball rotates with minimal frictional resistance, allowing for high-precision smooth motion.

Classification of linear bearing with balls
(1) Standard type, clearance adjustment type linear bearing, open type linear bearing, extended type linear bearing, universal type linear bearing
(2) The flange type linear bearings can be divided into: circular flange type, flange type, elliptical flange type, guided circular flange type, guided flange type, guided elliptical flange type, and extended circular flange type.
Classified by specification and format:
It is divided into two major series, namely LM and LME series. Its code name LM series is used in Asia, Southeast Asian countries, Japan, South Korea, China, etc. Based on metric dimensions, the outer diameter tolerance of the straight axis used is generally h7. The LME series is commonly used in Europe, the United States, Germany, Italy and other regions. The outer diameter tolerance of the straight axis used is generally g6, based on the imperial size standard. The structural characteristics of the two series are roughly the same, except for differences in size and aperture tolerances.

Divided by shape:
1. Straight cylinder type (shaped like a cylinder, usually installed with a snap ring, used for smaller installation sizes)
2. Flange type (with mounting flange at the end or middle, which can be installed with screws. The flange is generally divided into three types: circular, square, and trimmed)
3. Open type (shaped like a straight cylinder with axial slits on the surface, used in situations where clearance adjustment is required, divided into two types: large opening and small opening)
Classified by performance:
1. Ordinary type (for general performance requirements)
2. Super type (for situations with long lifespan and high load performance requirements)
