Stüwe Shaft nuts

Reliable axial component and bearing fixing

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
