New engine coupling offers easy stiffness adjustments
Ringfeder Power Transmission has developed a patent-pending engine coupling that optimizes torsional stiffness and misalignment tolerance across a wide torque range. This new TSCHAN TNR coupling is intended primarily for mobile and stationary diesel-driven powertrains. TSCHAN TNR Couplings consist of an aluminum housing and steel hub separated by one or two rows of mechanically-linked, cylindrical […]
Reduce lead times with new rapid response program
Ringfeder Power Transmission has launched a new Rapid Response program designed to reduce lead times by making some of its most popular products available for next-day shipping, if orders are taken by 12 p.m. EST. The program covers the most common sizes from two of Ringfeder’s most popular product lines — Shrink Disc locking devices […]
What is a hysteresis coupling?
By Zak Khan Hysteresis refers to a specific magnetic phenomenon. Certain magnetic materials, called ferromagnetic materials, have a tendency to remain magnetized to some degree even after the magnetic field they are subjected to is removed. This “memory of magnetic history” is referred to as hysteresis. This also means a magnetic field in the opposite […]
The 4 best coupling basics videos on the internet
Coupling videos are a dime a dozen on the internet. So which ones are the most helpful, the most interesting, the most worth your time? Well, we watched more coupling videos than we’d like to admit just to help answer that question for you. We’ve put them in a list. We did this because people […]
Coupling widens torsional stiffness range
Engine flywheel couplings have to strike a delicate balance when it comes to stiffness. On the one hand, they have to be rigid enough to transmit torque efficiently and avoid resonance problems. On the other, they have to be flexible enough to handle any misalignment between the motor and the drive shaft. The Ringfeder Power […]

Flexible vs rigid couplings: Part 2
This is the second installment in a weekly 3-part series on flexible vs rigid couplings. Here, Ringfeder’s Ed Cole shares his insight into the best options for different applications. This excerpt was taken from Cole’s presentation during the Design World Webinar, Flexible vs Rigid Couplings. Ringfeder is a manufacturer of transmission components, but today specifically […]
Flange couplings deliver higher torque capacity
Ringfeder Power Transmission’s RfN 5571 series of flange couplings, for heavy duty applications, offer easy installation and have higher torque capacity than standard press fits. Equipped with Ringfeder shrink discs, the RfN 5571 flange couplings can be integrated into machines without any heating or cooling, making them easily installable for engineers. They are slip fit […]
Ringfeder Power Transmission Group adds new line of heavy duty shaft couplings
Ringfeder Power Transmission Group has expanded its offering of heavy-duty couplings with the acquisition of TSCHAN GmbH, a leading supplier of non-shiftable mechanical shaft couplings. TSCHAN couplings are used primarily in heavily-loaded, large-machine applications—including mining, offshore, construction, steel production, cement, pump, compressor and power generation. These heavy-duty couplings complement the precision couplings from Ringfeder’s GERWAH […]
