Why Choose Ringfeder's Steel Disc Couplings for Precision Applications?

2.  Ringfeder – Setting the Standard in Disc Coupling Technology:

Ringfeder, founded in Germany, is a leader in mechanical power transmission with over 100 years of innovation. Known for quality and precision, its product range includes locking assemblies, damping systems, and advanced steel disc couplings like the TND HSH.

These couplings are engineered for high torque transfer, excellent misalignment compensation, and low inertia. Their modular design allows flexible configurations across industries such as robotics, steel, aerospace, and renewable energy.

Trusted globally—and locally in Vietnam through Dai Hong Phat Corp, the authorized distributor—Ringfeder ensures top-tier support, availability, and expertise.

3. Steel Disc Couplings TND HSH –  Maintenance-Free Couplings

The TND HSH maintenance-free operation through its robust all-metal construction. The Steel Disc Couplings in this series feature stainless-steel disc packs that resist wear, fatigue, and thermal variation. This results in a significant reduction in total cost of ownership (TCO) over the product’s life cycle.

By eliminating lubrication needs and inspection intervals, users minimize labor and spare part costs—often reducing maintenance-related downtime by over 70% compared to conventional couplings. The return on investment becomes evident within the first year, especially for industries running 24/7 operations.

For maximum safety and reliability in potentially explosive environments, RINGFEDER® Steel Disc Couplings TND HSH can be manufactured in full compliance with the ATEX Directive 2014/34/EU and the applicable standard DIN EN ISO 80079-36:2016. This certification ensures that the coupling is suitable for use in Zone 1 and Zone 2 (gas) as well as Zone 21 and Zone 22 (dust) in accordance with the EU classification of hazardous locations.

3.2. Key Highlights of Ringfeder's Disc Couplings:

• High Torsional Rigidity: Offers exceptional angular stiffness, allowing precise shaft alignment and accurate torque transfer even under demanding loads.

• Backlash-Free Design: Ensures consistent performance in reversing operations, improving the longevity of connected equipment.

• Maintenance-Free Operation: The robust, all-metal construction eliminates the need for lubrication and regular servicing.

• Flexible Yet Rigid: While it compensates for axial, radial, and angular misalignments, the coupling remains torsionally stiff for accurate torque transmission.
  Temperature & Corrosion Resistant: Operates reliably in harsh environments and is suitable for ATEX-compliant applications in explosive atmospheres (Category 2G/2D as per 2014/34/EU).

• High-Speed Capability: Designed for high-speed rotating machinery, supporting safe, vibration-free operation.

4. TND HSH Steel Disc Couplings Are Ideal for High-Precision Applications

For maximum safety and reliability in potentially explosive environments, Ringfeder Steel Disc Couplings TND HSH can be manufactured in full compliance with the ATEX Directive 2014/34/EU and the applicable standard DIN EN ISO 80079-36:2016. This certification ensures that the coupling is suitable for use in Zone 1 and Zone 2 (gas) as well as Zone 21 and Zone 22 (dust) in accordance with the EU classification of hazardous locations.

Thanks to their non-sparking, all-metal design and no friction-producing parts, these couplings are an ideal solution for explosion-risk applications in industries such as:

• Oil and Gas

• Chemical Processing

• Mining

• Power Generation

• Pharmaceutical Manufacturing

• Food and Beverage Production

Each ATEX-compliant coupling is carefully engineered to eliminate ignition sources and is rigorously tested to meet the stringent safety requirements. Upon request, Ringfeder provides the necessary documentation and markings according to the specific ATEX zone classification and equipment category.

With this level of safety assurance, Ringfeder TND HSH couplings provide peace of mind and legal compliance for engineers and plant operators working in hazardous environments.
