Ring and seals

Secure your assemblies

Tension rings to ensure firm seating of your rubber and metal assemblies

Tension rings or flat rings for ball joints are coiled in double layers from spring high-quality materials with a low-burr cut. Our engineers have developed special cut and shank geometry to avoid any damage in the final assembly. 

Tension rings assure firm seating on our customers’ rubber and metal assemblies. We have developed the materials used here with our suppliers to offer you a robust system with a high degree of radial force and excellent assembly precision.

Due to the increase in demand for flat materials, our internal rolling line is growing steadily, rolling tons of material annually to provide a fast cost-effective response for our customers.
