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. How are the locking pins installed on this locknut?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. Can I reuse the TSNX 513 S locknut and its locking pins?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. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
