(Code: DF). Notes: 1. Since the bearings are manufactured in a set to adjust for the internal clearance or pre-loading, parts with same serial number must be used for assembly. 2. Combination of more than 3 bearings may occur. Please consult NTN Engineering for details. r r. ¡The distance "l" between the cone pressure
