Linear bearings have many manifestations on many machines. The development of our machinery is also progressing. Metal linear bearings are a low-cost linear motion system that is used in conjunction with a cylindrical shaft with an infinite stroke. It is widely used in sliding parts of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, printing machinery and so on. The consumption of linear bearings also has its limitations. The most important thing is that the impact load capacity of the bearing is poor, and the carrying capacity is also poor. Secondly, the linear bearing has greater vibration and noise during high-speed motion. Let me introduce the classification of linear bearings.
1. According to the specifications:
It is divided into two series, namely LM and LME series. Its code name LM series is used in Asia, Southeast Asian countries, Japan, Korea, China, etc. With the metric size as the standard, the outer diameter tolerance of the linear shaft 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 outer diameter tolerance of the linear shaft is generally g6. The structural characteristics of the two series are roughly the same except for the different sizes and aperture tolerances.
2. Divided by shape:
a. Straight cylinder type (the shape is like a cylinder, and is generally installed with a circlip, which is used for small installation occasions).
b. Flange type (the end or the middle has a mounting flange, which can be installed with screws. The flange is generally divided into three types: round, square and trimmed).
c. Open type (shape like a straight cylinder, with axial slits on the outside, used in occasions where gap adjustment is required, divided into two types: large opening and small opening).
3. According to performance:
a. Ordinary type (used for general performance requirements).
b. Super type (for long life and high load performance requirements).
