PEX

The PEX coupling is a torsionally flexible, fail-safe and encapsulated claw coupling made of grey cast iron with elastomer elements.

These rubber elements made of NBR are the heart of the elastomer coupling. They transmit the torque and compensate for axial, radial and angular shaft misalignments. At the same time, the flexible packages ensure important factors such as damping and torsional stiffness.

The PEX cam coupling is available in two different designs. The coupling type B is a two-piece design consisting of a pocket part (part 1) and a one-piece claw part (part 4). 

The shaft coupling type A is a three-part design consisting of a pocket part (part 1) and a screwed claw part (part 2+3). This design allows easy replacement of the coupling packs without dismantling the coupling hubs or the motor.

The coupling hubs are standard for cylindrical finish bores with keyway and set screw, which we insert according to customer specifications. In addition, special bores or profile splines are also possible on request.

Advantages

• Extensive standard range

• High availability

• Favourable price-performance ratio

• Vibration-damping

• Simple mounting

• Breakdown-proof

Areas of application

The areas of application of the PEX compensating coupling can be found in the entire field of general mechanical and plant engineering, such as pumps and compressors, conveyor systems, mixers, gearboxes, etc. The PEX compensating coupling is also very suitable for applications in adverse environmental conditions, such as cement works, quarries, etc. Due to the encapsulated design, it is also very well suited for applications in adverse environmental conditions such as cement works, quarries, gravel and ballast works etc.
