SPIROL offers a line of austenitic stainless steel Disc Springs in diameters ranging from Ø8mm to Ø71mm. Austenitic stainless steel is typically used for static and low cycle applications that require a heightened level of corrosion resistance. It withstands fresh water and atmospheric marine conditions very well, and is suitable for many other industrial conditions including acidic environments. This material will continue to work harden with use so cycle life is limited, but creep resistance is good. SPIROL supplies both single Disc Springs as well as Pre-Stacked Disc Springs in custom configurations, packaged in shrink wrap with a perforated tab for easy of assembly.

Since the development of coil springs in turret tooling, engineers have been challenged to increase the productivity of turret presses even further. In a traditional press, the option of material type and material thickness is limited by the coil springs inability to produce a high force in a short linear distance. When this performance is necessary, coil springs will have a negative effect on the quality of the formed product and efficiency of the manufacturing process. SPIROL® Disc Springs are the solution to form thick materials, large extrusions, and more complex designs. When stacked in series, they are capable of providing a greater, more consistent stripping force than coil springs and require less space. They have become an instrumental component in the advancement of turret punch press tooling. Visit www.SPIROL.com to learn more!

The mechanical back-up design uses SPIROL® Disc Springs. Under normal circumstances, the hydraulic system holds a constant pressure on Disc Springs stacked in series. If pressure fails to be maintained, the stack of Disc Springs decompresses to actuate the braking mechanism. A compression spring or wave spring is not capable of providing the force required (in the space available) to actuate the brakes. The reliability of this safety system is dependent on the consistent performance of Disc Springs. In this critical application, the Disc Spring’s performance and level of predictability improves product quality and ensures overall safety. SPIROL® Disc Springs have a high capacity to consistently store releasable mechanical energy. Visit www.SPRIOL.com to learn more!

DEWALT’s lead design engineer for drills was tasked with designing a high power right angle drill that is lightweight, compact, and portable. The goal with the design was to maximize performance while minimizing the size of the tool. The design would incorporate a mechanical clutch built to limit maximum torque output to 70 ft-lbs. Absent the clutch, with the huge gear reduction of 75:1, the drill would be capable of producing a lock rotor torque at the spindle of 175 ft-lbs, transmitted directly to the operator of the tool. It was determined early on that the clutching thrust required in the space available could only be achieved by a Disc Spring design. Compared to conventional coil springs, Disc Springs offer a higher load capacity in less space. Additionally, longevity and reliability is a high measure of quality for professional tools used on a daily basis. The life and performance warranty of the tool was reliant on the Disc Spring design.

SPIROL Standard Slotted Spring Pins SPIROL Standard Slotted Spring Pins have a slot width narrower than the wall thickness and thus do not nest or interlock. This feature, combined with a smaller expanded (pre-insertion) diameter, results in a number of advantages for SPIROL Standard Slotted Pins compared to ISO 8752 pins including: • Lower insertion force and smoother insertion. • Rounder pins, which in turn results in better conformance of the pin to the hole wall and eliminates the edge of the slot damaging the hole during insertion. • Lower stress in the spine of the installed pin. This results in longer pin life in shock or fatigue applications. • Ability to use automatic vibratory feeding of pins for installation without interlocking. • Plating of pins for additional corrosion resistance or appearance without “touch marks” or the bonding of nested pins.

SPIROL invented the Coiled Spring Pin in 1948. Truly an engineered fasteners, the Coiled Pin is available in three duties, light, standard and heavy, to enable the designer to choose from the optimum combination of strength, flexibility and diameter to suit different host materials and application requirements. Their shock absorbing design dampens forces and vibration to prevent hole damage and prolong assembly life. Light Duty Coiled Spring Pins are generally recommended for soft, brittle or thin materials such as plastics, aluminium, die castings, ceramics, and where holes are located close to an edge of the assembly. In situations not subjected to significant loads, such as when used purely for alignment or as an axle, light duty Coiled Pins are often used because of easy installation resulting from lower insertion force.

With laser generation, components are built up layer by layer from powdered metallic materials used in serial production such as 1.2709 steel or 1.4543 steel. Thanks to state-of-the-art technology, this enables us to transfer your computer-generated 3D/CAD models reliably over to their physical form. Here, thin coats of the powder materials are applied to a base object before being melted using a laser into the desired contour. This process is continued on a revolving basis until the workpiece is complete with the final geometric form and the relevant functional properties. Incidentally, we reclaim excess powder material during this process and use all of it for later productions again. Our services in sample development also include technical springs, which we produce in small batches for your sample application. Traditional sample development services are a new addition to our portfolio. Here, we produce a small-scale series of your bent strip parts from original materials.

SPIROL manufactures Coiled Spring Pins out of 316 stainless steel to meet specific application requirements. Type 316 stainless steel is similar to 302/304 stainless steel with a slightly higher nickel content and the addition of molybdenum. The molybdenum content increases the chemical resistance of this alloy greatly. 316 exhibits superior pitting resistance against sea water, acetic acid vapors, chlorides, sodium and calcium brines, hypochlorite solutions, phosphoric acid, and the sulfite liquors and sulfurous acids used in the paper and pulp industry. This alloy is also austenitic, non-magnetic and non-hardenable using conventional methods. 316 stainless steel has better mechanical properties at elevated temperatures than 302/304 and offers excellent mechanical integrity at subzero temperatures. Typical applications for SPIROL's 316 Stainless Steel Coiled Pins include the following: marine, processing equipment, industrial, oil and gas and medical.

The COMPENSER® of the DC-series is an ideal hydraulic shock reducing element especially for the application field of storage technology (storage and retrieval machines). As a doubleacting buffer, this industrial shock absorber can be used in a spacesaving manner due to its design and can be actuated alternately from both sides. The constructive design and function corresponds to the C-Type. Furthermore, due to its low reset force, it can easily be pressed in at creep speed during operation. As optional equipment PU caps as inserts for the impact cap for the reduction of impact noise and a monitoring of the piston rod‘s position (by either magnetic or inductive sensors) are available. If only a slight increase of reset force of the piston rod over the entire stroke is desired, an additional external accumulator can be fitted to the cylinder to increase the gas volume of the gas spring. Hence the reset force decreases in retracted state.
