Oilite bronze for slow revving extreme torque applications like oil expellers, drilling rigs, tunnel borers and the likes.
Anyway, I would be very wary of fitting anything that would be metal to metal contact when the rubbers fail. At least with the Centa, when it fails you have to get the vehicle recovered but there is little damage other than simple replacement of the rubbers. Metal to metal could lead to a very expensive disaster indeed.
