The new transmission coupling FLENDER N-BIPEX can easily meet the customer’s needs, and it is perfectly interchangeable with the principal products, which are currently on the market, by offering the best performances at an interesting price.

The use of high quality materials and the study of the new cam profile has considerably improved this coupling performances, by making it suitable for heavy operations.


The principal features of this new coupling are:

  • High capability of absorbing torques pick (up to 3 times nominal torque)
  • High temperatures operation (-50°C up to +100°C)
  • Excellent relation price-performance
  • Rationed sizes in order to reduce the costs and the replacements availability
  • High performance elastomers for a uniform distribution of the transmitted cargo
  • Reduced weight, simple monitoring, short delivery time
