Tension Spring
Springs that can stretch, and then take their original shape, are called - extension springs .
Their working principle is very simple.
In the normal state, the turns of wire twisted in a special way fit snugly together, and in use, when the spring starts to work, these turns stretch, but tend to return to their original state.
Despite their rather simple device, these products are widely used in all areas of our lives due to their effective work.
They can be seen:
· on door closers in almost every home;
· in the device of the car;
· in the mechanisms of the train.
Description of extension springs
Expanding springs can have the following parameters:
· Wire thickness .
· Finished product diameter.
· The length of the spring at rest and the maximum length in use.
· The number of working turns.
· Maximum stiffness and tensile force of the spring.
· starting force.
Specifications of Tension Springs
Each manufactured product undergoes strict control for compliance with technical specifications.
For example, springs are tested for resistance to various influences:
· static;
· shock;
· dynamic.
Therefore, our customers are confident in the quality of our product.
All offered types of springs can be found in our catalog .
The product offered by us can have a different form of hooks, depending on the requirements of the customer for the finished product.
Also, we are ready to offer a wide range of fasteners in the form of studs and eyelets.
If a regular loop is installed at the spring, then such a product will have a large coefficient of elasticity. As a rule, a "glass" will be added to the loop spring, which is responsible for the smooth and even travel of the contracting spring.
To install a spring with a loop, you will need to use a special puller, since the loop eye is small.
