Helical Disk Spring Power Packs

This power pack is composed of a quadruplicated screwed together helical disk spring.
It is applied in hydrogen fuel cells featuring a high energy density for instance (e.g. satellites / submarines).

Spring Combinations and Sets

Whenever a single compression, tension and helical disk spring alone does not meet the requirements, we individually design spring combinations and spring sets for our customers. By this means, we achieve significant successes regarding spring loads, operational safety, durability and installation length.

Helical Disk Springs

With our patented helical disk spring, Roehrs can offer our customers a proven and tested machine component, which in many cases replaces the common multi-layer disc spring assembly.

Overview: Roehrs Helical Disk Springs

Automatic Mechanical Disk Spring Washer Style Clamping Systems

The mechanical disk-spring washer style die clamping system is designed for clamping dies of various widths on press slides. The clamping actuator moves automatically in the T-slot of the press slide between the park position and the respective die. Clamping is performed by belleville spring washers and hydraulic unclamping.

Surge Dampers

- Multi-wire spring element with very high damping behavior, even at high variations in temperature
- Different spring designs to meet customer requirements
- Resistant to oil, grease, solvents etc.
- High operational safety due to high energy absorption

Spring Stacks

Spring stacks are used in machining spindles for mechanically generating the actuation force for the clamping means.
