Available in 10 sizes made of nodular cast iron, Flender N-Bipex Couplings feature optimized cam and elastomer geometry. Elastomers are available in 3 different shore hardnesses, and allow couplings to be used across temperature range of -50 to +100°C without compromising nominal torque. Adjacent cam ring made of high-grade polyurethane has facility for sufficient load dependent deformation, while remaining in designated position under all conditions, resulting in minimized wear.
