Fenner Drives Keyless Locking Devices From the moment the wheel came into existence, man has been faced with the seemingly simple task of mounting his invention to a shaft so that something useful could be accomplished . Though it has been over 5,500 years since these rotating components have made their way into use, many designs still utilize mounting methods not much improved from the days of antiquity . These traditional connection methods include: interference fits (shrink or press), keys and keyways, splines and quick detachable bushings. In the sections that follow, we compare and...

Why Go Keyless Today’s global marketplace demands precise, efficient machines that optimize productivity while minimizing material and fabrication costs. When compared to traditional connection methods, Fenner Drives Keyless Locking Devices offer the following advantages: A mechanical interference fit with a uniform pressure distribution similar to that achieved through a shrink or press fit. The flexibility to mount over existing keyways if desired. A true zero backlash shaft-to-hub connection with none of the operational drawbacks of keyways or splines. The ability to mount on plain...

Trantorque or B-LOC : the Enduring Question ® Once you have decided that a keyless locking device is the right solution, your next big decision is which series of Fenner Drives Trantorque or B-LOC Keyless Locking Device to choose. While the underlying engineering principle for both Trantorque and B-LOC is exactly the same, the functionality of each may appeal to different applications and situations. Shaft Size Range Overall Length Range Torque Transmission Axial Movement Self Centering SELECTION ASSISTANCE Trantorque GT Trantorque Mini Shrink Discs Selection Assistance

SelfLocking Tapers Recessed Installation Without Counterbore RoHS Compliant Very Good Most applications, however, consist of a shaft and bored component that require the use of a keyless bushing. Many more factors play into the proper selection of a keyless bushing and are briefly addressed below and in the accompanying table. Shaft Size Very Good Very Good Shaft size may immediately determine whether you use a Trantorque or B-LOC Keyless Bushing. A Trantorque can accommodate shaft sizes as small as 1/8" (3mm) while the smallest shaft a B-LOC will fit is 1/4" (6mm). At the other end of the...
