According to the appearance and structure, linear bearings can be divided into standard linear bearings, adjustable linear bearings, open linear bearings, extended linear bearings, stamped linear bearings, and flanged linear bearings. Among them, flanged linear bearings can be divided into standard circular flange type, standard square flange type, standard oval flange type, pilot circular flange type, pilot square flange type, pilot oval flange type, long circular flange type, long square flange type, long oval flange type and long centered circular flange type, long centered square flange type and long centered oval flange type.
According to different specifications and standards, linear bearings are divided into 3 series:
Asian metric LM (SM / LB / KLM) series:
Mainly used in Southeast Asian countries, Japan, Russia, Korea, China, etc., with linear shafts of g6 and h6 outer diameter tolerances;
European metric KB (LME) series:
Mainly used in the United States, Germany, Italy, etc., with linear shafts of h6 and j6 outer diameter tolerances;
Inch SW (LMB) series:
Mainly used in the United Kingdom, the United States and so on, with linear shafts of g5 and h5 outer diameter tolerances.
The linear bearings of the above three series have the same structure except for little different diameters and tolerances.
According to a different performance, linear bearings can be divided into:
Ordinary type: General performance requirements;
Super type: Combined of engineering plastics and steel, with the adjustable feature, longer service life and larger load capacity.
At present, linear bearings are more widely used in food processing machinery, packaging machinery, medical machinery, printing machinery, textile machinery, robots, machine tools, automobiles and digital 3D coordinate measuring equipment and other precision equipment or special machinery industries. ISUTAMI can provide high-quality linear bearings with standard specifications from Chinese manufacturers, with inner diameters ranging from 3-60mm.
