ROFLEX-SH SHAFT COUPLING & N-EUPEX A

5/5 - (1 vote)

Currently, many factories are using N-Eupex A (Flender – Germany) elastic couplings in the transmission system. However, when delivery times are long, costs increase or replacement sources need to be proactive, Roflex-SH Shaft Coupling (Ringfeder – Germany) becomes a reasonable alternative thanks to its compatible design, equivalent quality and flexibility in operation.
The following article will analyze why Roflex-SH is a reliable choice to replace N-Eupex A in many industrial applications today.

1. Overview of KTR Roflex-SH and Flender N-Eupex A couplings:

Through the technical comparison table, it can be seen that Roflex-SH and N-Eupex A have many similarities. The special point is that the rubber couplings between the two types can be interchanged, which brings flexibility in actual operation and maintenance.

2. Why can Roflex-SH effectively replace N-Eupex A?

Based on the comparison table, it can be seen that Roflex-SH Shaft Coupling can completely replace N-Eupex A in many practical applications without changing the transmission structure. In actual operation, many factories using N-Eupex A have switched to Roflex-SH for the following technical and practical reasons:
– Compatibility of coupling damping rubber: Both Roflex-SH and N-Eupex A couplings have the same number of rubbers for each coupling set, which is very important and directly affects the torsional stiffness and damping ability during operation.
> >>> When the number of rubbers is the same, engineers can use compatible washers from Roflex-SH in case of quick replacement for N-Eupex A, minimizing downtime.
– Both products are manufactured in Germany, using high-quality materials and high-strength NBR rubber. The ability to reduce vibration, reduce moment shock and cushion durability are all at a high level – helping to protect equipment and extend maintenance time.

3. When should you choose Roflex-SH Shaft Couplings to replace N-Eupex A?

Replacing couplings in the transmission system depends not only on performance but also on other operating factors. Roflex SH is a reasonable choice in the following cases:

3.1. N-Eupex delivery time is too long:

In many markets, ordering N-Eupex can take 6–10 weeks. Meanwhile, Roflex SH has a faster delivery time. Currently, KTR Roflex-SH couplings are about to arrive at Dai Hong Phat warehouse, products are available, fast delivery

3.2. Enterprises want to synchronize equipment:

If a factory has used equipment from KTR such as shaft locks, shock absorbers, etc., choosing Roflex-SH will help synchronize the brand, facilitate maintenance and easy quality control.

3.3. Easy installation and alignment design

Roflex-SH coupling with a separate hub design on one side, is a short shaft coupling consisting of three parts used to transmit torsional vibration reduction force, making it easy to assemble/disassemble through four bolts, allowing for space-saving installation and suitable for systems with limited space.
>>> Thanks to the above features, Roflex SH not only ensures transmission efficiency but also helps factories optimize maintenance and operation processes, minimizing machine downtime and related costs.

4. KTR Roflex-SH coupling available at Dai Hong Phat warehouse

A clear advantage when choosing Roflex-SH is that this product is now distributed by Dai Hong Phat – the official authorized dealer of KTR Germany in Vietnam – and has a large stock.
