TSCHAN / RINGFEDER Couplings

About TSCHAN / RINGFEDER Couplings

All series of renownedTSCHANCouplings, globally leading in the field of non-shiftable mechanical shaft couplings, are now available under the strong brandRINGFEDER. These high-performance couplings have proven themselves for decades in demanding heavy-duty applications, e.g., in the steel and metal industry, building and construction machinery, material handling, diesel-electric engineering, power generation, mining equipment and special drive technology solutions.

RINGFEDERshaft couplings (formerlyTSCHAN) aredesigned for connecting two shafts in all industries. They are used in many machines, from small precision instruments and machines to heavy drives in conveyor system drives, cranes and other highly stressed drives in the steel, paper, chemical and rubber industries.

TSCHAN Is Now RINGFEDER

• Elastomer Jaw Couplings TNM

Vibration damping, rotationally resilient, fail-safe, misalignment compensating: Elastomer Jaw Couplings of the RINGFEDER TNM series previously TSCHAN TNM and NOR-MEX set standards worldwide in terms of flexibility, cost-effectiveness and performance. The axially pluggable RINGFEDER Elastomer Couplings of the TNM series can be used in a temperature range from -30 C to +100 C as well as in any installation position and direction of rotation.

• Elastomer Jaw Couplings TNS

The enormously powerful and resilient Elastomer Jaw Couplings of the RINGFEDER TNS series formerly known as TSCHAN TNS are the preferred choice of leading plant manufacturers and operators, especially in the field of highly demanding heavy-duty applications. These torsionally flexible and fail-safe quality couplings are optimally used e.g., as drive components in a wide variety of construction and building machinery as well as in steel, mining and cement plant technology, but also as connecting elements in overhead, container and casting cranes.

• Elastomer Jaw Couplings TNB

High-strength Elastomer Jaw Couplings of the proven RINGFEDER TNB series once TSCHAN TNB convince globally in the most demanding heavy-duty applications by superior durability and functionality for maximum operational reliability of the machines and plants of their users. The puncture-proof and torsionally flexible couplings effectively compensate for axial, radial and angular shaft misalignment and prove to be extremely robust against even the most adverse environmental conditions such as extreme temperatures or heavy dirt and dust creation. Accordingly, they are preferably used in steel, rolling mill and cement plants, in mining and construction machinery, e.g., bucket wheel excavators, shredder facilities and tunnel boring machines, as well as in offshore technology.

• Steel Disc Couplings TND

Torsionally rigid, absolutely backlash-free steel disc couplings of the new series RINGFEDER TND originating from the proven TSCHAN POSIMIN and GERWAH series are suitable for the most diverse applications and particularly ideal for all drive tasks requiring freedom from wear and maintenance as well as excellent misalignment compensation and positioning accuracy.

• Gear Couplings TNZ

Torsionally rigid and low-backlash gear couplings of the RINGFEDER TNZ series former TSCHAN TNZ and POSIFLEX are made of high-strength steel and are proving themselves worldwide in all industrial sectors where extraordinarily high torques must be transmitted from shaft to shaft. These include particularly heavy-duty applications, e.g., in the direct drive of conveyor systems, mixers, rolling mills or roller tables.

Versatile and Reliable Power Transmission

TSCHAN / RINGFEDER jaw-type flexible couplings are trusted for their superior misalignment compensation and robust performance across a wide temperature spectrum of -30C to +120C. Designed to support a load range of 180 Nm to 16,000 Nm and limiting speeds up to 10,000 rpm, these couplings ensure steady and efficient drive operation in diverse industrial settings, thanks to their high torsional stiffness and low noise emission characteristics.


Easy Maintenance and Serviceability

Routine maintenance is simplified with the flexible spider design that enables fast replacement without having to move adjacent shafts. This service-friendly feature translates into reduced downtime, ensuring continuous performance for your operational needs. The couplings are maintenance-free with no lubrication required, delivering long-lasting reliability and convenient operation.


Safety and Durability You Can Trust

With resistance against oil, grease, and commonly encountered industrial chemicals, TSCHAN / RINGFEDER couplings assure long operational life. The phosphated or painted finish boosts protection against corrosion, while materials like steel, cast iron, and polyamide ensure strength. Elastomeric seals and an integrated spider retainer further enhance durability and performance stability.
