In addition to SPIROL Standard Metric Slotted Spring Pins, SPIROL offers a line of ISO 8752 Slotted Pins to meet market demand for these pins. SPIROL offers Slotted Spring Pins manufactured to the ISO 8752 specification in diameters ranging from 2mm to 12mm in both high carbon steel and austenitic stainless steel in plain finish. ISO 8752 Slotted Pins are not available with supplemental coatings such as zinc plating or passivation due to their propensity to interlock during the finishing process.

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.

Spring isolators can be used for source and sender vibration isolation. The springs are manufactured of a special spring steel wire and KTL coated. Every spring isolator can be provided with an additional damping cushion of stainless-steel. Elemente with a frequency range between 3-4 Hz can be provided with a viscous damping, too. Spring isolators with a natural frequency range of 3-5 or 4-6 Hz are especially made for higher forces. They can be expanded in size and load-capacity without any difficulty. Spring isolators of RG+ are available for four different natural frequency ranges: Spring isolators with a natural frequency of 3-4 Hz Spring isolators with a natural frequency of 5-6 Hz Spring isolators with a natural frequency of 7-9 Hz Spring isolators with a natural frequency of 3-5 or 4-6 Hz

Constant Force Springs are manufactured from flat strip material and spooled to a specific curvature matching the needed pull force. There is practically no limit on extension speed and acceleration. The springs can be fitted in a number of ways and extended partly or completely.

The Series 550 Cosmetic Coiled Pin was designed specifically for cosmetic cases to ensure the perfect balance of strength and flexibility. The 1-1/2 coil construction ensures that the Cosmetic Coiled Pin exerts sufficient radial force to achieve the long-term desired swing torque while protecting the plastic from excessive stresses. The use of SPIROL Series 550 Cosmetic Coiled Pin will simplify your design and manufacturing process. Uniform radial spring force results in controlled hinge movement and a hinge quality that remains consistent over time. Controlled hinge movement is achieved with wider tolerances and lower moulding costs than when a Solid Pin or cut wire is used. Finally, low insertion force and compression of the pin during installation minimises hinge stress and scrap. The net result is the prolonged useful life of the 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 ounterbalancing spring-loaded hinge from EMKA is an efficient, robust and flexible hinge especially designed for various chests. The hinge is manufactured in various sizes and different spring load capacities. The hinge can be ordered freely to attach to the lids of chest and facilitate smooth operation. As per the weight of the chest's lid, the hinge can be regulated for spring loads accordingly through an adjusting nut in the socle, in order to keep the lid in a particular position. Hinges are available for lids weighing from 6 to 23kg. After installing the hinge on lid, the cover (included in the package) can be put on easily.
