LM / ZG Models

The LM model uses an aluminum alloy as the hub material and stainless-steel round wire for the coil spring. The long type of the LM model (the LM-1 type) allows a particularly large angle of deflection of up to 14°.
The ZG model uses a zinc alloy as the hub material and spring-steel square wire for the coil spring.
Select the type suited to your usage environment.
