Stüwe Locking Nut TYP SLN

Stüwe shaft nuts enable simple, secure and precise fixing of machine elements against axial displacement. They are suitable for a wide range of applications, such as securing bearings in wind turbines or as central fastening on drives of various industrial machines (e.g. three-star motors).


  • No holding groove on the shaft necessary
    - Smaller shaft diameters can be realized
    - No notch effect
    - Less manufacturing effort
    - No weakening of the shaft
  • Frictionally engaged connection of the threads possible by tightening the bolts
    - Minimization of tooth backlash
    - Increase of the tooth meshing area
    - Absorption of highest axial forces
    - Easy assembly and disassembly due to slotted ring
