Belleville
Disc Springs
Maximum force in minimum space. Belleville washers (disc springs) are conical-shaped rings designed to support extreme loads with very short travel distances. Perfect for heavy bolted joints, valve actuators, and heavy machinery requiring massive pressure damping.

Features & Advantages
Why disc springs are essential for heavy engineering.
Delivers exceptionally high compressive forces within an extremely small axial space compared to traditional coil springs.
Discs can be stacked in various combinations (parallel or series) to infinitely tune the load and deflection characteristics on the fly.
When stacked in parallel, the friction between the discs provides inherent shock absorption and hysteresis damping.
Maintains high bolt tension under severe temperature fluctuations, preventing heavy flange joints from leaking.
Heavy Duty Applications
Supporting massive forces in critical infrastructure.
Bolted Joints
Maintaining preload in power plant busbars and heavy industrial pipe flanges.
Valve Actuators
Providing the fail-safe return force in massive safety valves for oil and gas pipelines.
CNC Spindles
Securing the tool drawbars in high-speed machining centers.
Power Transmission
Absorbing shock and maintaining pressure in heavy-duty clutches and brakes.
