Notes: 1. T.C.=Torque Capacity. The maximum transmissible torque is twice the T.C. 2. Keyway size is not listed in the table. Keyway size is per ISOR773 DIN6885.1 unless the bore is preceded by an asterisk (*). If bore is preceded by an asterisk, keyway is per DIN6885.3. 3. Minimum overrunning speed of inner race should not be below listed value during continuous operation. 4. Max. engagement speed must not be exceeded when transmitting torque.
