What is the knowledge about the lubrication grooves and lubrication holes of spherical roller bearings?

For the convenience of lubrication, spherical roller bearings can provide spherical roller bearings with lubrication holes and lubrication grooves on the outer ring, and W33 is added to the bearing post-code. Spherical roller bearings with lubrication holes on the outer ring are added with W20 in the bearing post-code.

Our factory can provide customers with spherical roller bearings of other structural forms, such as spherical roller bearings with retaining grooves on the outer ring, single-row spherical roller bearings (angle error can reach 4°) and other products. If customers need, please consult us. In addition, our factory can also design and manufacture other spherical roller bearing types that meet customers' personalized requirements.
