Notes on use | Sunco Spring Co., Ltd.

Wire

To prevent wire cutting, the wire should be attached so that it will not rub against the pulling outlet of the bracket or any other parts.
If a pulley is used for changing the wire direction, the pulley must meet the following figure.
NWS, NWT, and NWS-OD Types ≥ φ30 mm
NWG and NWH Types ≥ φ40 mm
Use it within the specified wire stroke.

* CONSTON springs are assumed to be used under a static load. Thus, do not apply any shocking load to them.

Cushion ball

The NWG and NWH Type products have a rubber cushion ball attached, in order to reduce the damage from the shock caused by the wire pulled inward at a stretch, for example, when it is released from the operator’s hand.
* Avoid any design that requires the operator to make the cushion ball work every time.
