Tips: Types of Linear Bearings

1. According to the material, the SHELL of linear bearings can be made from stainless steel, bearing steel or aluminum alloy (linear bearing with seat); CAGE: resin, stainless steel or bearing steel; SURFACE TREATMENT: chrome plating, nickel plating or surface anodization

2. According to the shape, linear bearings can be divided into open type and closed type; straight column type, single liner type (ordinary type), double liner type (extended type); single liner type with flange, double liner type with flange; double-sided cutting flange type, middle cutting flange type, four-sided cutting flange type; heightened square with fixed seat (fixed seat made of aluminum alloy, surface anodized), widened square with fixed seat, etc.

3. According to the series, linear bearings are divided into two series, namely LM and LME series. The LM series are used in Asia, Southeast Asian countries, Japan, Korea, China, etc. LME series are mostly used in Europe, America, Germany, Italy and other regions. The structural characteristics of the two series are roughly the same except for the different sizes and aperture tolerances.
