Product description

One of the most demanding challenges on our promise of performance is the belt drum application field. The extreme loads which such components are subject to, especially the high bending moment, coupled with the simultaneous indispensable reliability and longest-possible service life require the highest in engineering know-how.

RINGFEDER® Locking Assemblies

These are the original and premium internal locking devices, fitting inside a component or hub. These units are most commonly used on applications in general engineering to transmit high torques and axial loads. Common types include 7012, 7013.0, 7013.1, 7014 and 7015.0. Most are available in metric more

RINGFEDER® Shrink Discs

These external clamping devices fit on the hub projection of the component and elastically compress the hub onto the shaft to transmit torque. Designed to be utilized as a single or in a split configuration, these devices transmit high torque. Common types include light duty, medium duty and heavy duty more

RINGFEDER® Flange Couplings

RINGFEDER® Flange Couplings are the better alternative to press fits. Neither additional components such as keyways or wedges, nor a warming of the outer section and cooling of the inner section are required. The flange coupling is simply pushed onto the shaft and fastened so it is frictionally engaged more

RINGFEDER® Friction Springs

RINGFEDER® Friction Springs consist of separate conical inner and outer rings which stack together to form a column. Under compressive loading of the column, the wedging action of the tapered rings expands the outer ring and contracts the inner ring allowing for axial deflection and, therefore, absorption more


The TSCHAN® TNS coupling is a torsionally flexible, shock-proof claw coupling. It compensates angular, radial and axial shaft misalignment within specified tolerances. With the TSCHAN® TNS coupling, the torque is transmitted via a compressed elastic intermediate ring. The elastic intermediate ring absorbs more


The rotationally resilient, failsafe claw coupling TSCHAN® TNB series is flexible in all directions and therefore compensates for angular, parallel and axial shaft misalignments of the connected machines. Misalignments can be caused, for example, by inaccurate assembly, heat movements or settling phenomena. more


The TSCHAN® TNR is a novel non-shiftable coupling. The distinctive feature of this coupling type is that its dynamic characteristics can selectively be adjusted over a wide range while maintaining its overall dimensions. This coupling has specifically been designed and optimized by TSCHAN for use primarily more


The TSCHAN® Safety Couplings series TNT are specially designed for highest demands in heavy duty industries. In each version, whether as Flange-, Servo-Insert or Rigid Disc Coupling a positive-locking torque transmission is guarenteed. A precisely adjustable disengagement torque, easy handling as well more

TSCHAN® TNM (Nor-Mex®)

The rotationally resilient coupling of the TSCHAN® TNM series is flexible in all directions and therefore compensates for angular, parallel and axial shaft misalignments of the connected machines. Misalignments can be caused, for example, by inaccurate assembly, heat movements or settling phenomena. more


The POSIFLEX® coupling is a torsionally rigid twin cardanic gear coupling. The coupling housings have a straight internal toothing whilst the hubs have an external toothing with a chased variable radius. As a result, the hubs can move spatially within the housing and thus compensate angular, radial and more


The barrel couplings complement the portfolio of the well-proven TSCHAN® couplings for crane and hoisting gear applications. The comprehensive range of TSCHAN® drive couplings that connect the driving motor with the gearbox and which are generally equipped with brake discs or brake drums, where required, more

ECOLOC Locking Assemblies

RINGFEDER has excelled in offering premium quality locking devices to the market for almost a century. With the same outlook on quality, but at a more economical price, RINGFEDER is pleased to offer the Ecoloc devices for budget conscious customers. Budget friendly internal locking devices offer a variety more


The Servo-Insert Couplings of the series ECOLOC ECE are used wherever vibration damping is required. By an optimization of the spider an increased shaft misalignment compensation is achieved. The power transmission happens through a positive-locking keyway more


Tooth couplings of the series ECOLOC ECT are designed for positive torque transmission by simultaneous compensation of axial, radial and angular shaft misalignment. Due to the curved tooth the couplings are almost maintenance-free. They are also characterized by an easy installation, high mechanical more
