Classification of linear bearings

(1) Standard type, clearance adjustment type linear bearing, open type linear bearing, extended type linear bearing, universal type linear bearing

(2) Flange type linear bearings can be divided into: circular flange type, method flange type, elliptical flange type, guided circular flange type, guided method flange type, guided elliptical flange type, and extended circular flange type.

Classified according to specifications and formats:

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 matched straight shaft is generally h7. The LME series is mostly used in Europe, the United States, Germany, Italy and other regions. Based on English dimensions, there are also metric dimensions, and the outer diameter tolerance of the straight axis used is generally g6. 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 occasions)

2: Flange type (with mounting flanges at the end or middle, which can be installed with screws. The flanges are generally divided into three types: circular, square, and trimmed)

3: The open type shape is like a straight tube, with axial slits on the surface, used in situations where clearance adjustment is required, divided into two types: large opening and small opening

By performance:

1: Ordinary type (for general performance requirements)

2: Super type (for situations with long lifespan and high load performance requirements)
