BDNB Series Clutch
The Bi-Directional No-Back offers an extraordinary combination of functions at low cost. The basic function of this unit may be easily adapted to a large range of applications requiring automatic position holding with rotary driven capability.
The BDNB can be turned only when torque is applied to the input shaft. The input shaft may be driven in either direction with torque being transmitted directly to the output shaft.
When there is no torque on the input, the output shaft is “locked” and cannot be rotated in either direction. Any torque applied to the output shaft is transmitted directly to the clutch body, and will not be reflected to the input.
