Curved teeth engage with the matching pulley better than standard trapezoidal teeth, so these belts transmit about twice the torque. All are compatible with Gates PowerGrip HTD, Omega HP, and Carlisle RPP series.
Neoprene—Durable and weather resistant, but lose elasticity if exposed to oil and fuel. These belts are reinforced, so they’re strong enough to transmit power without stretching. Plus, nylon-coated teeth minimize friction and protect the surface from wear.
