Detailed introduction:

The NL drum gear coupling is a new domestic product and has been widely used. It is suitable for flexible transmission between shafts and allows large axial and radial displacement and angular displacement. It has a simple structure, The advantages of convenient maintenance, easy disassembly and assembly, low noise, low transmission efficiency loss, and long service life are very popular with users.The shaft hole types are cylindrical (Y), conical (Z) and short cylindrical (J).The shaft hole and keyway are processed in accordance with the standard GB3852-83 "Coupling shaft hole and keyway form and size".The working temperature is -20～+70℃.

Order marking method:
For example: NL4 internal tooth elastic coupling (keyway according to GB3852-83 standard)
Active shaft: d1=38 L1=80
Driven shaft: d2=30 L21=50
