RINGFEDER's Fundamental Approach RINGFEDER manufactures buffers (coil springs) that are incorporated into the coupling parts of railway vehicles, in addition to fastening elements such as the Schupan ring, supplying them to EU countries and surrounding nations. RINGFEDER applies its know-how in the structure and materials of coil springs to Schupan rings and shrink discs, and as a pioneer in friction fastening elements, it focuses on "the application of high-elastic materials" and "stable supply," as well as "advice on the limit design of elements," "development of application technology," "trouble resolution," and "harmony between elements and counterpart components" in its technical services. The Schupan Ring is RINGFEDER's Original Product! Due to the remarkable nature of its basic design, many counterfeit products have emerged since the patent expired. However, the Schupan ring is an original friction fastening element developed by RINGFEDER in Germany under ISO9001 quality management, consistently manufactured from materials to heat treatment and finishing processes. It is highly regarded as the only product that benefits from high-quality technical support from the RINGFEDER technical department and has sales channels in major advanced countries.

Clamping Sleeve The DSK-DSL, DSM, and AK-AL/IK-IL series are machine elements developed for the rapid and high-precision fastening of shafts and hubs through friction. This innovative shape enables high-precision fastening and makes assembly and disassembly very easy. Additionally, even when there are dimensional constraints in the axial or outer diameter directions at the fastening part, you can always find a form and size that meets your requirements from each series. These series ensure that the inner and outer diameters deform elastically and uniformly in the radial direction by applying pressure axially, securely fastening around the rotation axis. They also excel in dynamic balance, making them ideal for high-speed shafts. The DSK-DSL and AK-AL/IK-IL series conform to finishing tolerances of h5 (max. h6) for shafts, while the DSM series is specialized for motor shafts, with the counterpart shaft tolerances conforming to k6 for φ50 and m6 for φ55 and above. We also offer the DSM-S1 series that conforms to some h6 tolerances, so please inquire. Furthermore, we have various technical information available, so please be sure to contact us during the design phase.

Unique products utilizing the Japara shape Precision Lock Nut The MSR, MSA, and MSW series are lock nuts that eliminate play in the screw flange section and allow for high-precision seating adjustments (perpendicularity). Their unique cross-sectional shape characteristics align the spindle axis with the nut's center, while simultaneously enhancing locking force, making them ideal lock nuts. Their high axial rigidity tolerates high levels of dynamic stress and locks without relying on the friction of the seating surface, allowing for delicate preload adjustments required by high-speed bearings. Additionally, the outer circumference is cylindrical, providing excellent dynamic balance, making them optimal for high-speed shafts. The finishing accuracy of the threads is ISO 5H "fine" grade.
