1. When purchasing linear bearing products, be sure to prepare the equipment and check factors such as product speed and load. If the equipment requires high rotation accuracy, we can choose ball bearings; users should choose according to specific usage requirements to improve procurement efficiency.

2. Users should also consider the combined radial and axial loads of the bearing when purchasing products. If the radial load is large, deep groove ball bearings can be used, and when the axial load of the device is small, the thrust angle can be used.

3. The angle between the linear bearing and the outer ring should be controlled within the allowable angle deviation range. Users should pay attention to this when selecting to extend the service life of the equipment and reduce the additional load on the bearing.

4. The stiffness requirements of linear bearings are also an important factor in user selection. The efficiency of the product can be improved by selecting the stiffness of the hardness. The high rigidity of the bearing system can improve the rotation accuracy of the shaft, help the product improve the use efficiency, help the equipment reduce vibration noise, and improve the quality of the operating environment.

Linear bearings are divided into two series, namely LM and LME series. Its code name LM series is used in Asia, Southeast Asian countries, Japan, South Korea, China, etc.

    LME series are mostly used in Europe, the United States, Germany, Italy and other regions. The structural characteristics of the two series are roughly the same except for different sizes and hole diameter tolerances.

    Example 1: LM 203242 UU OP

LM represents the first series of straight line standards

203242 indicates the size structure, aperture, outer diameter, length

UU means double seal structure OP means open type

    Example 2: LME 203245 UU AJ

LME stands for Linear Second Series Standard

203245 indicates the size structure, aperture, outer diameter, length

UU means double seal structure AJ means gap is adjustable
