Type 2 non-metallic insert hexagon lock nut mainly plays the role of anti-loosening and locking in mining machinery and equipment. This kind of nut is pressed against the external thread by Njogu ring or nonmetal material embedded in one end of the internal thread, which increases the friction, so that it can be locked and loosened. Specifically, the thickness of type 2 non-metallic insert hexagonal lock nut is thick, which is suitable for occasions where it is often necessary to assemble and disassemble. Moreover, when the non-metallic insert is screwed into the external thread, it will destroy and fill the gap of thread fit, increase the resistance when circling, and play the role of locking.
In mining machinery and equipment, because the equipment usually needs to bear large vibration and impact load, the traditional metal nut may loosen under these conditions, which will affect the stability and safety of the equipment. Through its special design, type 2 non-metallic insert hexagonal lock nut can effectively prevent this situation and ensure the long-term stable operation of the equipment.
It is suggested that the following points should be paid attention to when using type 2 non-metallic insert hexagon lock nut:
Tighten with a torque wrench to achieve the specified fastening force.
After locking, the nut should be at least 2~3 threads beyond the screw to ensure sufficient locking force.
After a period of use under vibration load, the nut should be tightened again to achieve the best fastening state.
When the Njogu ring or nonmetal material in the nut rotates relative to the parent body, it should be stopped immediately to avoid damaging the nut structure.
