akn Precision Locknut with M65x2 thread

Description

This akn TSNX 513 S is a high-precision stepped locknut engineered for applications that demand high accuracy and rigidity. It is designed to secure bearings on a shaft, eliminating clearance and ensuring precise axial positioning. The use of axial locking pins provides a secure and vibration-resistant connection, superior to traditional locknuts with washers.

FAQ

What is the correct tightening torque for the TSNX 513 S locknut?

The correct tightening torque is application-specific and depends on the required bearing preload. Always refer to the machine manufacturer's assembly manual or akn's technical documentation for precise torque values. Over-tightening can damage the bearing.

The TSNX series uses axial locking pins that are driven into threaded holes on the face of the nut. These pins engage with the shaft's keyway or a pre-drilled hole to prevent rotation. Ensure the pin is seated correctly for a secure lock.

While the locknut itself is generally reusable if the threads are undamaged, it is highly recommended to use new locking pins for each installation. Reusing pins can compromise the locking security and lead to loosening under vibration.
