Elflex Pin & Bush CouplingsElflex Pin and Bush Couplings are cushioned drive type couplings that transmit the torque through rubber bushes which have an excellent capacity to absorb shocks. A barrel shape of the bushes guarantees a uniform distribution of loads, even in case of misalignment, thus limiting the bending moment resulting from the radial force on the pins. Bushes are composed of a NBR element containing natural rubber. The hardness of the rubber element is 72°Shore A. |
