CAPT Units

The TransDrive CAPT (Clamping and Anti-Pullout Tapered) units are designed to provide a secure and high-performance shaft-to-hub connection. These units utilise a precision-engineered tapered bushing or sleeve that clamps the shaft and hub together, creating a strong, interference-based fit. The taper enhances grip, minimizing slippage while optimising torque transmission. Additionally, TransDrive CAPT units feature advanced anti-pullout mechanisms, preventing axial movement and ensuring stability even in high-load, high-stress applications.

Beyond traditional keyways, TransDrive CAPT lock assemblies function as keyless locking solutions, using radial compression and expansion to generate a comprehensive 360-degree clamping force around the shaft. This friction-based locking method provides superior holding power and eliminates issues associated with wear and backlash found in conventional keyway systems. Due to their durability and reliability, CAPT lock assemblies are widely uses across various industries, including timing mechanisms, drum and conveyor pulleys, sprockets, sheaves, gears, agitator shafts, and hydraulic clutches and brakes. These features make TransDrive CAPT units an ideal choice for applications requiring precision, strength, and longevity in power transmission and mechanical systems.
