RINGFEDER® TNM coupling

The rotary flexible couplings of the RINGFEDER® TNM series are flexible in all directions and therefore compensate for angular, parallel and axial deflection of the shaft of connected machines.
Our TNM coupling is a suitable alternative to the FLENDER N-EUPEX coupling with better torque and speed transmission!
 
The construction consists of three parts, the replacement of the middle elastic ring takes place without axial movement of the driven parts.
Elastic intermediate ring in various hardnesses: standard Pb72, hard Pb82.

General features:

• Torsionally flexible coupling, compensates for angular, radial and axial shaft misalignment
• Elastomers available in different degrees of hardness as required.
• Suitable for temperatures from -30 ° C to + 100 ° C
• Elastic intermediate ring can be replaced without having to move the built-in machines (three-part models)
• Holes up to max. 280 mm
• Torques up to TKn = 41,000 Nm / TKmax = 97,500 Nm
• Speeds up to nmax = 5,000 rpm
