When the standard range does not fit: special sizes and custom development
When a joint needs a spring the catalogue does not carry, the answer is not always a redesign. SCHNORR offers an extensive standard range together with a multitude of special size disc springs, plus customer specific solutions and special developments, and specialises in tailor made solutions developed in partnership with customers, going further than DIN […]
How to read a disc spring drawing: the tolerances that decide whether it fits
Disc spring tolerances are specified in four places: overall height, thickness, load and diameter. Each one lands somewhere different in your assembly. Height and thickness stack up over a column of springs, diameter decides how the spring sits on its guide, and load tolerance decides whether the force you calculated is the force you get. […]
Turbochargers, shock absorbers and brake boosters: what a car asks of a spring
Disc springs for automotive applications have to do three difficult things at once: deliver high force in almost no space, survive millions of cycles, and hold that force while the surrounding metal heats and cools. SCHNORR disc springs are used in turbochargers, shock absorbers and brake force amplifiers, and are trusted across automotive, energy, heavy […]
Stamping machines, spindles and percussion drills: springs that live under impact
Impact duty punishes springs. Disc springs for machine tools cope because they are largely self damping, deliver high loads from a short stack, and have a long, predictable service life under dynamic load. SCHNORR components are used in stamping machines, spindles, percussion drilling machines and sliding hubs in conveyor drives, where the load arrives suddenly […]
Rail clamps, ski lifts and elevator brakes: joints that must not move for twenty years
Stationary railway clamps, ski lift cable clamps and emergency brakes in elevators are all joints where the clamping force has to survive years of thermal movement, weather and vibration without maintenance. Disc springs for rail applications and lift applications hold that force because a series stack absorbs movement while keeping the load roughly constant, and […]
Disc spring stacks: how series and parallel stacking changes the force you get
A disc spring is a cone shaped washer that carries load along its axis. On its own it does something no coil spring can: it delivers a very high force in a very short installation length. Understanding how disc springs work in stacks is what turns that into a design tool, because the same part can be arranged to give you travel, load, or a curve that changes as it compresses.
