Locking Assemblies

The TransDrive locking assemblies enable swift and efficient shaft connections, saving time by eliminating the need for keys.

The TransDrive Locking Assembly, also known as a Self-Locking Unit, provides a high-strength, keyless connection for industrial applications requiring reliable torque transmission and resistance to thrust, bending, and radial loads. By converting locking screw clamp loads into radial contact pressures, it creates a zero-backlash interference fit, ensuring a secure, wear-resistant connection that wont loosen or degrade – even under high-cycle, fluctuating, or reversing loads.

When the locking unit bolts are tightened, the plates engage with both the shaft and the inner circumference of the mounted component, evenly distributing pressure for a secure and unform fit. The eliminates the need for keyways or grub screws, reducing machining costs and preventing common issues like wear or component damage. Designed for high-performance, maintenance-free operation, TransDrive Locking Assemblies provide a superior alternative to traditional mounting technologies, delivering long-term durability and precision in demanding applications.
