Bearing Locknuts – TCN

Ruland TCN bearing locknuts offer a secure, high-performance solution for precision spindle and AFBMA-standard shafting applications. Featuring a one-piece clamp-style design, they provide greater axial holding power than traditional round bore collars and are easier to install and adjust than solid ring locking devices. Precision double-tapped threads ensure a burr-free fit, simplified installation, and longer shaft life. Manufactured from 1215 lead-free steel with a black oxide finish, these locknuts are available in standard sizes from N00 to N14.
