Engineering support

We help you select or design the component you need

Before supplying a part, Surisa's engineers work with the customer to understand the application: the load, the travel, the service temperature, the corrosive environment or the space constraints. From there they select the right component, size stacks and configurations, and recommend the material and treatment. When needed, custom parts are ordered through a network of top-tier specialized suppliers.

What support includes
  • Component selection and sizing, as well as its installation method (for example, stacks in disc springs)
  • Choice of material and treatment according to standard (DIN, EN, ISO, AISI) and working environment
  • Troubleshooting fatigue, relaxation, corrosion or hysteresis in elastic components
  • Definition of special parts outside standard sizes or materials
  • Cross-references and replacement of part numbers from other manufacturers
