Electric insulated roller bearing for traction motor NU212 C3 VL0241
The model of insulated bearings is mainly distinguished by suffix codes to distinguish out ring insulated bearings and inner insulated bearings:
The model representation method of insulated bearings is similar to that of ordinary bearings, but with some additional suffixes to identify their insulation characteristics. These suffixes directly reflect the insulation part of the bearing, that is, outer ring insulation or inner ring insulation. Specifically:
The suffix codes of outer ring insulated bearings usually include VL0241, J20A, J20AA, J20B, V3031A (JXKJZC), which are used to indicate that the outer ring of the bearing has an insulating coating.
The suffix codes of inner ring insulated bearings include VL2071, J20C, V3031B (JXKJZC), which are used to indicate that the inner ring of the bearing has an insulating coating.
Choose the appropriate installation method: For the installation of cylindrical bore bearings, for small bearings with interference fit (D<=100mm), the bearings can be pressed onto the shaft or housing by mechanical or hydraulic methods. For larger bearings (D>100mm) or when the interference is large, the principle of thermal expansion and contraction can be used for installation. Generally, oil bath heating or electric induction heating is used. The installation of tapered bore bearings with tapered inner holes is installed by interference fit.
By following these steps, you can ensure the correct installation of the insulated bearing, thereby extending its service life and maintaining good insulation properties.
