End Force

Vlier spring-loaded devices or spring plungers are designed to exert a precise end force in the right place at the right time. End forces range from .125 to 200 lbs. Standard spring-loaded devices are available in heavy and light end force designs.

Travel

A major characteristic of the spring-loaded device or spring plunger is its range of motion or travel. Through the range of travel, end force increases (due to spring compression) from initial to final as the plunger or ball is depressed. The product specification tables in the online catalog portion of this website provide initial and final end force values for all Vlier spring-loaded devices.
