Description of the beta spring pin

The beta spring pin takes its name from its shape, which looks like the Greek letter beta. This safety part’s role is to tightly fit another part of a mechanical assembly. As a matter of fact, as a pin, on mounted parts, it has a shearing action when the device is exposed to huge pressure or overload.

Torsion spring

We manufacture torsion springs to meet simple or complex requirements. They can be manufactured from standard machines or specific tools.

Wire form spring

Wire forms are used for a wide variety of applications. Pins, hooks, clips, electrical contact parts, and more, they can be manufactured from standard machines or specific tools.

Flat spring

Flat springs are made using special tools. They can be produced following their morphology on a radial or linear press. RHD has seasoned experts on both types of machines.

Sub-assembly spring

RHD can offer its customers the option of pre-assembly on machine during production in order to shorten the assembly stages and achieve productivity improvements. We are also able to assemble our part with a part supplied by the customer.

Specificities of the pin-type beta

Used mainly in the automotive industry, the beta spring pin belongs to the elastic springs’ family. It is often used to tighten classic and castellated nuts. Unlike the cotter pin, the beta pin has the advantage of being reusable after removal of all mechanical parts.

Thus, the safety pin is required, among other things, to clamp a car’s axle transmission pins mounting and to assemble and fasten a farm equipment’s parts.

On the very long list of items whose smooth functioning requires one or several small springs,  one can see lighters, watches, robots, but also industrial machines, bottles of perfume, shock absorbers. People generally ignore that springs play a crucial role a huge number of objects for everyday use. The high mechanical and sometimes thermal or chemical stresses to which springs are exposed combined to their small dimension require manufacturing processes to comply with the highest quality standards. Cutting-edge sectors, such as automotive, pharmaceutical or high-tech industries place a high value a high degree of importance on the springs used in their products.
