Linear bearings are classified according to specifications

Divided into two series namely LM and LME series. Its code name LM series is used in Asia, Southeast Asian countries, Japan, Korea, China and so on. Taking the metric size as the standard, the outer diameter tolerance of the linear shaft used is generally h7. LME series are mostly used in Europe, America, Germany, Italy and other regions. The inch size is the standard, and there are also metric sizes. The tolerance of the outer diameter of the linear shaft used is generally g6. The structural characteristics of the two series are roughly the same except for the different sizes and aperture tolerances.
