Fenner Drives - Power Transmission - Keyless Locking Devices - Trantorque® GT - Steel - Inch
| Overview: | |||

| Description: | |||
Features of Fenner Drives Keyless Bushings: All Fenner Drives keyless locking devices operate using the simple wedge principle. An axial force is applied- by either a hex nut (Trantorque) or a series of annular screws (B-LOC)- to engage circular steel rings with mating tapers. The resulting wedge action creates a radial force on the tapered rings, one of which contracts to squeeze the shaft while the other expands and presses into the component bore. |
