Siemens N-BIPEX Claw Couplings

With its cast hubs, the N-BIPEX allows greater freedom when designing the cam geometry, thereby laying the foundation for the innovative Curved Design. Compared to the milled cams typically available on the market, this design results in uniform loading of the elastomer compression bodies under all conditions and, in particular, prevents inward deformation of the cam ring due to load peaks that can cause greater wear. Hubs made of high-quality nodular cast iron allow the N-BIPEX to cope with high rotational speeds and critical bores.

N-BIPEX provides reserves that are considerably greater than those normally available on the market, thus achieving a significant reduction in wear.

The elastomers used in N-BIPEX are designed for peak performance. The specially optimized material allows it to achieve top values for the relevant criteria: compressive strength, abrasion resistance, dimensional stability and deformation capability. The relevant performance characteristics of the material remain stable over a very wide temperature range, allowing it to be used from -50 °C to +100 °C without limiting the nominal torque. For the end user, this means not only greater process reliability but also a saving potential with regards to the coupling size required.

Product benefits

High torque reserves (maximum torque = 3 x nominal torque) to effortlessly absorb torque peaks, e.g. when an asynchronous motor is running up to speed
Savings due to unrestricted use at temperatures ranging from –50 °C to +100 °C
An excellent price-performance ratio across all coupling sizes
Reduced complexity and lower storage costs due to the use of a single hub to meet all requirements
High-quality elastomers that ensure a uniform load distribution and thus an optimum service life under all conditions
Different cam ring Shore hardnesses
ATEX certification
Low weight
Simple assembly
Short delivery times due to a large range of standard bores

Application examples

N-BIPEX couplings are employed in many branches of the mechanical engineering industry. The main areas of application are well-aligned electric-motor drives with uniform torque loads, e.g. hydraulic applications or in combination with geared motors.
