bearing lock nut

Because ZENSO precision locknuts can improve the assembly accuracy,better spindle flexing,coule be easily mounted and dismantled,ont easy to let-off,and also could prolong the working life of workpieces,they are widely used whenever precision mechanisms require a precision clamping as well as a powerful and safe locking.

The variety fo ZENSO precision locknuts are included:

Machine tool

Textile industry

Printing industry

Centrifugal machine

Turbocompressor

Conditioning

onshore and offshore lndustry

Transportation

Aeronautics

Marine equipment

Nuclear industry

Construction machinery

Special machinery

Other special locknuts

Material:

ZENSO precision locknuts are made of high quality C45 steel,with black and oil-soaked surface treatment.optional material:42CrMo,40Cr,stainless steel ect.optional surface treatment:galvanizing,nickel plating,phosphating,etc.

Mounting:

The mounting for ZENSO locknuts can easily achieved.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’s blocked,then tighten up the screw in turn.for lock screw tightening torque,please refer to catalog.

Dismantling:

Dismantling the nut with no locking pin,only need unlocking the grub screws.dismantling the nut with locking pin,when unlocking the grub screws,the pin is not loosen to gear to the shaft screw.using the rubber mallet gently tap the nuts near the locking screw,then the locking pin loose,screw off the nut.phosphor bronze locking pins can not deform in tensioning,so the nut can be reused for many times.
