Lubrication Groove and Hole
In order to lubricate easily, LYC can provide the bearing with groove and holes on outer ring, in this case, W33 should be added behind the original bearing code. If the outer ring has only one lubrication hole, W20 will be added behind.
LYC can design spherical roller bearings with other structures, such as bearings with snap ring groove on the outer ring, a single row spherical roller bearing (angle error can be 4°), and many other types etc. If customers require, then please consult LYC technical department.
LYC can also design and manufacture spherical roller bearings with special structures according to customer’s requirements.
