DB keyless locking bushes

DB keyless locking bushes transmit torque from the shaft to the hub by friction, without a key and without weakening the shaft with a keyway. They perform well wherever a component must be precisely positioned angularly and quickly removed during servicing.

DB keyless locking bushes - high torque and conveyor drums

The DB type is used in pulleys and couplings transmitting high torque and in conveyor drums. The frictional connection has no play, so it does not wear like a classic key, and removal requires no heating or pullers - machine downtime is shorter.
