TransDrive CAPT (Clamping and Anti-Pullout Tapered) Lock Units are engineered to secure, high-performance shaft-to-hub connection in demanding power transmission applications. Using a precision-machined tapered sleeve or bushing, these units clamp and hub together to create a strong interference fit that maximises grip and improves torque transmission.

The tapered design increased contact pressure between the shaft and hub, helping minimise slippage while maintaining reliable performance under heavy loads. Integrated anti-pullout features further enhance stability by preventing axial movement, making CAPT units well suited to high-stress operating environments.

Unlike traditional keyed connections, TransDrive CAPT assemblies function as keyless locking devices, using radial compression and expansion to generate a full 360-degree clamping force around the shaft. This friction-based system eliminates issues such as backlash, wear, and keyway damage commonly associated with conventional locking methods.

TransDrive CAPT Lock Units are widely used in applications including conveyor and drum pulleys, sprockets, sheaves, gears, agitator shafts, timing systems, and hydraulic clutches or brakes, providing a reliable solution where strength, precision and long-term performance are essential.
