(1) Basic type, gap adjusting type linear bearings, open mouth linear bearings, extended linear bearings, universal linear bearings

(2) Flanged linear bearings can be divided into: round flange type, method orchid type, oval flange type, guided round flange type, guided method orchid type, guided oval flange type and extended round flange type.

According to the specification, model and style:

It is divided into two series of products, LM and LME. LM series products are used in Asia, Southeast Asia, Japan, Korea, China and so on. The applicable linear spool diameter tolerance is generally h7 based on the imperial size. LME series products are mainly used in Europe, abroad, France, Spain and other places. With inch thread size as the benchmark, there are also male inch size, the applicable straight bobbin diameter tolerance is generally g6. The structural characteristics of the two series products are roughly the same except for the difference in size and diameter tolerance.

Divided by appearance:

1: straight cylinder shape (like a round barrel, generally installed with a circlip spring, used for assembling smaller places)

2: flange type (top or middle is assembly flange, can be assembled with screws, flange generally divided into ring, square and edge cutting type three)

3: The appearance of the opening mouth is like a straight cylinder, the surface has radial slit, used for the place where the gap must be adjusted, divided into large opening and small opening 2 kinds)

By feature:

1: Universal (the use of general performance test solutions)

2: Unusual type (place with long service life and heavy load performance test solution)
