1.systematization: 

1). metal linear bearing and Plastic linear bearing

2). Standard, Clearance SetUp Coordinatelinear bearing, Open mouth linear bearing , The stretched linear bearing , 

General linear bearing.

3). Flange linear bearing can be divided into: round flange type, method, elliptical flange, round flange type, guidance method orchid type, orientation ellipse flange type, extended type circular flange .

4). LM and LME series. Its code LM series used in Asia, southeast Asia, Japan, South Korea, China, etc. Metric size as standard, with the straight axis diameter tolerance is usually h7. LME series is much used in Europe, the United States, Germany, Italy and other regions. Inch size as standard and metric size, with the straight axis diameter tolerance is usually g6. Two big series structure features, in addition to the different size, diameter tolerance is different, its structure is roughly the same.

    Plastic linear bearing can be divided into two major series with LIN -12 and LIN - 11 series, its code name LIN - 11 is the representative of a European standard plastic linear bearing, and LIN - 12 series is narrow type design, mainly in order to save installation space and design; Distinguishes between two major series, LIN - 11 series is using circlip limit installation, and LIN - 12 series is directly mounted with its diameter and installing seat hole tight fit.
