Ringfeder Couplings
Ringfeder couplings are a type of mechanical coupling used to connect rotating shafts in heavy-duty industrial applications. These couplings are designed to transmit torque while accommodating misalignment and vibration between the connected shafts.
Ringfeder couplings have gained a reputation for endurance after 55 years of operating in the toughest of NZ’s trucking conditions. Ringfeder offers a comprehensive and proven range of couplings for hinged and rigid drawbar applications. The range includes couplings for 50 mm and 40 mm towing eyes.
The new generation high-quality Ringfeder trailer couplings are designed for improved operation and reduced maintenance costs, while providing unsurpassed reliability and extended product life.
FEATURES
Ringfeder couplings offer several benefits in industrial applications, including:
Improving performance – Adding value
Ringfeder couplings offer a wide range of products that can be used in various industrial applications

RF50 BNZ
The Ringfeder RF50 BNZ is a bolt-on, torsionally flexible coupling designed for use in heavy-duty industrial applications. It is designed to connect two rotating shafts while accommodating axial, radial, and angular misalignment, as well as shock and vibration.
The RF50 BNZ coupling consists of two hubs and a flexible element made of high-quality elastomer material. The hubs are made of steel and are designed to securely hold the flexible element in place. The coupling also features a patented locking mechanism that ensures the hubs are properly installed and aligned.
The RF50 BNZ coupling is suitable for use in a wide range of industrial applications, including pumps, compressors, and other machinery that require reliable and efficient torque transmission. It can handle high torque loads without slipping, and its flexible element can absorb and dampen vibrations, which helps to reduce noise, improve equipment performance, and extend the life of the connected equipment.

RF40 GI50B
The Ringfeder RF40 G150B is a type of flexible coupling designed for use in various industrial applications. It is a torsionally flexible coupling that accommodates misalignment and vibration between two rotating shafts while transmitting torque.
The RF40 G150B coupling consists of two hubs and a flexible element made of high-quality elastomer material. The hubs are made of steel and are designed to securely hold the flexible element in place. The flexible element can absorb and dampen vibrations, which helps to reduce noise, improve equipment performance, and extend the life of the connected equipment.
The RF40 G150B coupling is suitable for use in a wide range of industrial applications, including pumps, compressors, and other machinery that require reliable and efficient torque transmission. It can accommodate axial, radial, and angular misalignment, which helps to reduce wear and tear on the connected equipment and extend its service life.

Automatic Coupling Oiler
- Continuous lubrication of the coupling mechanism for optimal performance and reliability.
- No time-consuming and strenuous manual work – this especially applies to couplings in underslung position.
- Filled with special RINGFEDER Coupling Oil – with higher viscosity, adhesion, and corrosion protection.
- Easy to install.

Ringfeder type 2020
Ringfeder type 2020 couplings are a type of rigid coupling that are used to connect two rotating shafts in industrial applications. They are designed to transmit torque between the shafts without any flexibility, making them ideal for applications where precise positioning and alignment are required.
The type 2020 coupling is a single-piece coupling, made of high-quality steel, and is designed to provide a secure and rigid connection between two shafts. It is available in a range of sizes and configurations to suit different shaft sizes and torque requirements.
One of the key benefits of the type 2020 coupling is its simple and robust design, which makes it easy to install and maintain. It does not have any moving parts or flexible elements, which means that it is less prone to wear and tear and requires less maintenance compared to other types of couplings.
