Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new products allow users additional flexibility in their methods with out losing the compact design and high load capacity of a pin coupling.
pressure gauge octa -Eupex ERN is provided with a torque limiter, which offers much more

security within the drivetrain in plenty of purposes. The coupling variant permits customers to

specify a most torque so that critical torques for the motor and output machine

are not transmitted. Machines and systems are shielded from overload and

harm, thus considerably rising 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 example,
assembly or substitute of worn elastomers can be carried out much more simply.
No connecting machine components must 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 introduced as a “short

version” into Flender’s modular system. While ไดอะแฟรม ซีล , which was launched in

2020, addresses the pump market with commonplace expansion pieces for normed shaft

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

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

to the beforehand used rubber elements manufactured from NBR, Flender now also provides

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

improve for all N-Eupex couplings with NBR packings in 2020, using TPU

packings allows the ability density to be increased by another 20 p.c on

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

fabric inserts and the torque capacity is again raised.
“With a view to the long custom of cam couplings, our growth engineers are

systematically engaged on rising the number of combos even additional. The

2022 enhancements give our users a broad range of sustainable options for

optimizing their machines and systems much more and lowering upkeep,”

explains André Artmann, Head of Coupling Sales.
