Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new sorts. The new merchandise permit users additional flexibility of their methods with out dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides even more

safety within the drivetrain in lots of functions. pressure gauge 10 bar coupling variant permits customers to

specify a most torque in order that crucial torques for the motor and output machine

usually are not transmitted. Machines and systems are protected against overload and

harm, thus considerably increasing system availability.
With the N-Eupex B plus clamping element, Flender introduces a second new

coupling that ensures frictionally engaged clamping connections. In this case, the

plain, cylindrical machine shaft end is linked to the coupling hub through a clamping

connection without a feather key and repair ability is increased. For instance,
assembly or substitute of worn elastomers may be carried out much more simply.
No connecting machine components have to be moved, the time required is halved

and so is the downtime of the machine.
With the N-Eupex DKS, a new double-cardanic coupling is launched as a “short

version” into Flender’s modular system. While the DK type, which was launched in

2020, addresses the pump market with standard enlargement items for normed shaft

distances, the DKS is the shortest attainable double-cardanic resolution for the market.
The shortened general length allows cost-optimized use with a small shaft distance

dimension with out losing the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition

to the previously used rubber components made from NBR, Flender now also offers

elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque

increase for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU

packings permits the ability density to be increased by another 20 percent on

common. For sizes 300 and above, the familiar NBR elastomer is combined with

fabric inserts and the torque capability is once more raised.
“With a view to the lengthy tradition of cam couplings, our improvement engineers are

systematically working on rising the variety of combos even further. The

2022 enhancements give our customers a wide range of sustainable options for

optimizing their machines and techniques much more and decreasing upkeep,”

explains André Artmann, Head of Coupling Sales.
