| Bearings with designation prefix J:
ANSI/ABMA Standard 19.1 Check availability of tighter width tolerance to 6 X tolerance class (designation suffix CLN) or P5 Values: ISO 492 (table 1, table 2, table 3 | Check availability of CL3, CL0 or tighter width tolerance
Values: ANSI/ABMA Standard 19.2 (table 4) Deviating width tolerances for cups and cones are identified by a designation suffix (table 5). |

| The inner ring with roller and cage assembly (cone) and outer ring (cup) with the same basic designation are interchangeable. The tolerance for the total abutment width T of the bearing is not exceeded if the cones and cups are interchanged. | ||

misalignment |
SKF Explorer bearings:
Where misalignment cannot be avoided, SKF recommends not to use standard design bearings. The permissible angular misalignment between the inner and outer rings depends on the size and internal design of the bearing, the radial internal clearance in operation and the forces and moments acting on the bearing. As a result, only approximate values are listed here. Any misalignment increases bearing noise and reduces bearing service life. |
