3MM-WI manufactured with 25 deg contact angle, are for use on applications where the loading on the bearings is predominately thrust and a high degree of axial rigidity is a definite requirement. Typical applications for these are large vertical rotary surface grinders, horizontal and vertical disc grinders, and thrust bearing applications for heavy-duty lathes where the bearings must directly carry extremely high tail stock or chucking pressure.
