(1) standard type, clearance adjustment type linear bearing, open-mouth type linear bearing, extended type linear bearing, general type linear bearing

(2) Flanged linear bearings can be divided into: circular flange type, method blue type, ellipse flange type, guide circular flange type, guide method blue type, guide ellipse flange type, extended circular flange type.

According to the specifications:

It is divided into two major series, namely LM and LME series. Its code LM series is used in Asia, Southeast Asian countries, Japan, Korea, China and so on. With the metric dimension as the standard, the outer diameter tolerance of the matched straight shaft is generally H7. LME series are mainly used in Europe, the United States, Germany, Italy and other regions. The imperial size is the standard, and the metric size is also available. The outside diameter tolerance of the matched straight shaft is generally G6. The structure characteristics of the two series are roughly the same except for the difference in size and aperture tolerance.

By shape:

1: straight cylinder type (the shape is like a cylinder, generally installed with a clip spring, for the occasion of small installation size)

2: flange type (there are mounting flanges at the end or in the middle, which can be installed with screws. Flange is generally divided into three types: round, square and cut edge)

3: open shape such as straight cylinder, the appearance of axial slit, used for clearance adjustment occasions, divided into two kinds of large opening and small opening)

According to performance:

1: General type (purpose for general performance requirements)

2: super type (long life and large load performance requirements)
