Precision Locknuts

Application:

TDX precision locknuts can improve the assembly accuracy with better spindle flexing. They could be easily mounted and dismantled but not easy to let-off. The nuts also could prolong the working life of work pieces for cost-saving. They are widely used for precision mechanisms require a precision clamping as well as a capable and safe locking.

The variety of precision locknuts is as following:

Mechanical tool
Textile industry
Printing industry
Centrifugal machine
Turbo-compressor
Conditioning
Onshore and offshore industry
Transportation
Aeronautics
Marine equipment
Nuclear industry
Agriculture and food industry
Construction machinery
Special machinery
Other Special locknuts

Material:
The precision locknuts are made of high quality C45 steel with black and oil-soaked surface treatment. You also can order optional material 42CrM0, 40Cr, stainless steel and so on for different purpose. Optional surface treatment such as galvanizing, nickel plating, phosphating, etc. are available for your choice.

Mounting:
It is very easy to mount precision nuts as following instruction:

  • Screw the nut by driving the hook spanner or plug wrench according to rated tightening torque;
  • The necessary tightening torque depend on the required preload.
  • When preloading the nut, the lock screw should be screwed by socket head wrench lightly until you feel it is blocked, then tighten up the screw in turn.
  • For lock screw tightening torque, please refer to catalog.

     

  • Dismantling:

    • ó┘Dismantling the nut without locking pin, only need unlocking the grub screws.
    • ó┌Dismantling the nut with locking pin, when unlocking the grub screws, the pin is not loosen to gear to the shaft screw.
    • ó█Using the rubber mallet gently tap the nuts near the locking screw, then the locking pin loose, screw off the nut.
    • ó▄Phosphor bronze locking pins cannot deform in the tensioning, so the nut can be reused for many times.
