How can it help?

Designed for customization by simply attaching accessories at either end, the DBM Universal Spring Cylinder can be adapted to many uses and reduce custom design costs.

The spring loaded plunger incorporates a tapped hole with concentric pilot bore on the compression end and a threaded extension on the tension end. It is easy to add standard or custom accessories and create a device that fills a variety of needs--in compression or tension. It can also be used directly without accessories (as in indexing applications). Designed with precision tolerances, the DBM Universal Spring Cylinder is built to handle indexing and locating tasks. The hardened steel plunger extends completely through the body providing a large bearing surface for offset loads.

An optional retract lock is available for the threaded and non-threaded styles. Completely retracting the plunger and rotating it 90 degrees will hold the plunger in the retracted position. See example applications on the left.

We provide a number of options for mounting the DBM Universal Spring Cylinder. Plus, we offer numerous accessories for both the compression and tension end.
