Customised production to your specifications: We work very closely with you when it comes to producing torsion springs. Torsion springs are produced in accordance with your specifications based on drawings, prototypes or sketches. We manage the development process of the spring until it is ready for serial production. We produce torsion springs with wire diameters of 0.20 to 4.00 mm, with or without torque testing. Wire coatings: Galvanised, ZnAl-plated, Red-coated, Nickel-plated, Polished nickel, Phosphated, Brass-plated,Silver-plated.

Often, leg springs are also referred to as torsion springs. This derives from the fact that these springs often support rotating motions or also several shaft revolutions or trace them back to the initial point. The shape and size of the springs’ body und ends (for the most part tangentially or axially projecting legs) are very various and using the technology which is nowadays available they are efficiantly producible. Do not hesitate to ask us, we gladly optimize your applications with you.

Many applications require two similar springs, but with one right-hand coiled and one left-hand coiled. In some cases, these two springs can be combined into a double spring, which has one right and one left-hand coiled spring body connected to each other.

Torsion bar springs is a good alternative to clock springs or helical torsion springs, when a rotational torque is needed in applications where the spring shall fit into a space that is limited radially, but with lots of space axially.

Clock Springs – also called hair springs – is a torsion spring that is optimum for installation spaces that are limited axially, but with more space radially. They are made from strip material or flat rolled wire that is wound in a flat, spiral shape.

Precise, reliable measurements of both static and dynamic torques in either direction can be made with this range of sensors. This opens a wide range of possible applications to the user. These torque sensors are standard equipment in a wide range of industrial automation, quality control and automotive components industry applications, as well as in laboratories. Typical applications: Screwing technology — Checking and adjusting bolting tools such as torque limiting wrenches, screwdrivers — Testing bolted connections Measuring the drag torque of motors and pumps — Frictional torques of gears, bearings and seals — Testing torsion springs — Adjusting equipment in the automobile industry (sunroof, power windows etc.) Strain gauges are mounted on the torsion shaft of the sensor element, itself made of steel, connected to form a full bridge.

The model TNZ ZCAF is composed from the coupling halves of the coupling TNZ ZCA and is complemented by an intermediate shaft and two rigid counter-flanges. If required, the torsional stiffness of the shaft can be tuned to the dynamic behavior of the drive line. In addition, the intermediate shaft, which serves to accommodate longer shaft separations, can be mounted and dismounted radially without having to move the connected machines.
