RTP tire couplings consist of 2 hubs and a split tire element that is connected to the hubs by screws. Installation in case of use is very easy. Since only the tire transmits the power, the clutch is effective. In the event of an overload, the tire is destroyed and the machine is protected. If overload situations are only expected occasionally, the user may be able to do without a torque limiter. The polyurethane (PU) tire ensures a long service life under standard usage conditions.
