Note
Elastomer dog coupling consisting of two hubs and an elastomer coupling spider. They are suitable for compensating axial, radial and angular misalignments and for cushioning vibrations and torque shocks.
The polyurethane coupling spiders are available in various hardness grades. As the hardness of the coupling spider increases, the torque and stiffness transmitted increases, and as the hardness decreases, the displacement capacity and cushioning increases.
Pre-tensioning of the spiders in the coupling hubs make this variant play-free.
Supplied unassembled.

Assembly
The elastomer dog couplings have an H7 tolerance. The recommended clearance tolerance is 0.02 - 0.05 mm. This tolerance and lubricating the shaft journals aids assembly and removal.
For installation, the hubs of the elastomer dog coupling are simply pushed onto the shafts and secured with grub screws.
