SKF MS 3052-48

MS locking clips are locking devices, used to secure HM and HME lock nuts onto a shaft or adapter sleeve and prevent unintentional loosening. The locking clips engage a keyway in the shaft or adapter sleeve and one of the slots in the outside diameter of the lock nut. A bolt attaches the clips to the side face of the lock nut. A new locking clip should be used each time the corresponding lock nut is installed.
