Power Springs

Our high-quality Power Springs

Power Springs provide a high force output with minimal force requirements.

Our product range covers power springs from 12mm up to and including 40mm in diameter. Whatever loop length, internal housing or shaft diameter you require, we’re sure to have exactly what you’re looking for.

We can also create custom power springs that are made to order. Simply tell us the technical details, and one of our experienced team will be in touch to discuss your final design.

Fitting a Power Spring

To minimise friction, the spring should be lubricated when it is fitted and the coils separated. If no lubrication is applied, there may be a reduction in spring force of up to 20%.

If more torque is required, two or more springs can be placed next to each other. In such circumstances, it is preferable to position a washer between the springs.

The power spring is usually positioned in a housing with the outer hook located around a pin or in a slot on the housing with the smallest internal diameter as specified below.

You can also place it in a larger housing, but with an associated decrease in force. It should be positioned on a shaft with a groove in it, in accordance with the dimensions listed below. It is also possible to slightly increase the diameter of the inner coil for placement on a larger shaft.

Material and Finishings

Power springs are supplied with a protective ring or nylon band that you must remove during assembly. The spring should be handled with care and held using a suitable tool whilst being positioned in the housing.
