China Spherical Roller Bearing 22315MB/W33
Spherical roller bearings are inherently self-aligning and very robust. They have two rows of rollers which make the bearings able to carry heavy loads. Our TVB brand spherical roller bearings mainly includes CC, CA, CAE, MB and E type. TVB can provide a wide range of sizes of several ISO Dimension Series and also includes special designs. Special bearings can also be customized as required based on the standard bearings.
