1.The coupling is crown gear type instead of spur gear,At present,the external tooth of NL nylon gear coupling in China is pur gear.

 2.This structure is good for buffering & shaock absorption ,and it can compensate the deviations at axil ,radial and angle direction well.

 3.Due to the cooperation between engineerinng plastics and metal parts, the coupling has good self-lubrication performane and it is  a very ideal flexible coupling which is approximate to universal couplings.

 4.The nylon part is mold shaped which will simplify the processing nd reduce the cost ,and the service environment is -20+-+80.

 5.This structure is easy for assembling and repairment .the nylon part of B type and C type can be replaced by steel,please contact us for more details.
