Bore Code B - without keyway
Bore Code K - with keyway (from d1 = 30)
Blue BS - 80 Shore A
White WS - 98 Shore A
Red RS - 92 Shore A
GN2241 Elastomer Jaw Couplings, with Grub Screw
Elastomer jaw couplings GN 2240 can transmit very high torques while compensating for shaft misalignments and runout tolerances. They are preferred in applications where the focus lies on pure torque and power transmission.
The choice of three coupling spiders with different hardness values allows the properties of the coupling to be optimally matched to the specific requirements. The use of grub screws for clamping and the simple plug-in installation make jaw couplings very easy to assemble.
With the bore code K, the keyway is always integrated into both bores d2 and d3.
