Model K-Type -Highly Flexible Coupling

K couplings dampen torsional vibrations and torque shocks in the driveline. In add­ition, K couplings balance axial, radial, and angular displacements. The operational stability and service life of your plant or your vehicle are in­creased, which in turn in­creases availability and reduces life cycle costs.

Bell-house bearing models and models with torsional limiting device are optional.

Torque     up to 140 kNm
Speed     up to 13,000 rpm

• Bell-house bearing design (in cases where the engine crank shaft is not able to bear the weight of the cardan shaft and the coupling

• Resonance speeds are shifted into non-critical speed ranges. The system runs quieter, increasing comfort when operating the equipment or vehicle.
• Elastomer elements dampen torsional vibration peaks that occur in the driveline. Thanks to their elasticity, these elements reduce the stresses on the driveline caused by internal combustion engines or load-side units with their natural fluc­tuations in torque. Your system or vehicle runs with a high degree of operational durability. And that increases productivity.
• The coupling takes the load off all of the drive components, increasing their service life and reducing maintenance costs. The net result is a positive impact on the life cycle costs (LCC) for your system or vehicle – not to mention preventing consequential expenses arising from downtime.
• Its modularity makes this coupling extremely flexible with respect to function and design. You get a coupling that is precisely matched to your driveline`s technical and design requirements. Standardized components ensure an optimal cost/bene­fit ratio.
• The K coupling features a high torque capacity. You save installation space while at the same time transferring high torque safely and reliably.
