| Description |
BR-HT is mainly used in backstop applications as an integral part of a gear reducer. Prevention of reverse rotation for inclined conveyor and bucket elevator are typical application BR-HT assures not only the immediate backstop function under high torque, but also long service life by the “lift-off” design. In addition, installation on the high speed shaft with low torque enables selection of more compact models with resulting lower cost. Notes: Keyway No Mark on Bore Size...ISOR773 DIN6885.1 Overrunning speed of inner race should not be below under continuous operation. Engagement speed must not be exceeded when transmitting torque. |
