Cranes and hoists are only as good as the components that make them up. One of their key components is the coupling, which is essential to maintaining uptime and enhancing the safety and reliability of your operation. Without the right coupling, your crane or hoist may not function properly, causing your process to grind to […]

The high-quality original from the world market leader: RINGFEDER Shrink Discs are flange-shaped, friction-locked shaft-hub connections and the more powerful and reliable alternative to conventional shrink fits, wedge, keyway, or polygonal connections. In contrast to internal locking devices, e.g. locking assemblies, the pressure is applied from the outside to the hollow shaft or hub, thus […]

Reaching the required amount of torque in space-constrained power transmission systems — which is often the case for applications like servo drive brakes or emergency stopping brakes — can sometimes be difficult. Fortunately, our HTB high-torque, spring-set brake excels in these and other tough applications, thanks to quality materials, precision engineering, and a compact design. […]

The Proven Reliability of the FEA Fail-Safe Spring Set Electromagnetic Clutch By Ringfeder Editor When developing fail-safe systems for precise, delicate, or heavy-duty machine applications, components that deliver extreme reliability and high performance are invaluable. The FEA Fail-Safe Spring Set Electromagnetic Clutch features a durable design with high-strength components to provide high torque in a […]

By Ringfeder Editor Cranes, emergency stop equipment, and packaging machines all require optimal precision, durability, and performance in their braking systems. At the same time, ample installation space is often a luxury. Sacrificing performance to squeeze a brake into the available space can cause breakdowns, impacting operations and driving up costs. Instead, consider the HBB […]

Gasoline engines, pumps, generators, and other machines operating in rugged environments require long-lasting components to ensure successful performance. Clutches designed with durable materials can prevent breakdowns, which would otherwise lead to expensive maintenance and downtime. One example of a ruggedized clutch — the EPC multiple-disc electric pulley clutch — consists of a standard electromagnetic multiple-disc […]

HVLS (high-volume, low-speed) fans are generally ceiling-mounted and are less often of the wall-mounted type. They are more than 7-ft (2.1 m) in diameter. Their functional principle relies on size and not on speed to move a large amount of air. Though HVLS fans are used in a wide variety of applications, they are predominantly […]

When machines overload and break down, the ramifications can be costly, time-consuming, and dangerous. Implementing safety measures — like our MOR and ORI overload release mechanical clutches — can prevent these consequences, protecting your equipment, products, and operators. Avoid Major Shutdowns Both the MOR and ORI consist of our standard multi-disc mechanical clutches with additional […]

Ringfeder manufactures products that comply with the highest function and safety requirements set forth in the most diverse industrial fields worldwide. This also includes the entertainment industry: discover how its products are used in the impressive T-Rex from Creature Technology. Modern friction-locked connections, like locking assemblies and shrink discs, are state-of-the-art. They are ideal for […]

By Ringfeder Editor In mission-critical military applications or other rugged, high-performance environments, braking systems must provide superior functionality and excellent reliability. Ideal for these kinds of projects, the EMA multiple disc electric brake ensures smooth and safe operation, delivering three to six times more torque than a single disc electric brake of the same size. […]

How does a vibration damping system work? Vibration damping systems encompass energy-absorbing devices which are installed into the building structure to dissipate a large portion of the induced energy. Such energy absorption elements are not normally the main load-bearing components of a structure. Yet, structural deformation or vibrations cause these devices to move resulting in […]

Ringfeder’s Elastomer Jaw Couplings of the RINGFEDER GWE, TNM, TNS, and TNB series — originating in the proven GERWAH and TSCHAN series – meet the highest performance and durability requirements in a wide range of sectors, e.g. the steel and metal industry, drive and conveyor technology, power generation, machine tool, packaging and printing machine construction […]

A clutch that is both bi-directional and one-way might sound like a contradiction. But in fact, we offer just such a clutch. As a bi-directional clutch, the MTL can transmit torque from input to output shaft in either rotational direction. And, its one-way functionality prevents output shaft loads from backdriving into your other power transmission […]

Torsionally rigid, absolutely backlash-free steel disc couplings of the new series RINGFEDER® TND – originating from the proven TSCHAN, POSIMIN, and GERWAH series — are suitable for the most diverse applications and particularly ideal for all drive tasks requiring freedom from wear and maintenance as well as excellent misalignment compensation and positioning accuracy. The characteristic […]

1. Additional reinforcement of the building structure Earthquake-proof buildings generally consist of shear walls, cross braces, diaphragms, and moment-resisting frames. These components all serve to redistribute forces. For example, shear walls that are composed of several panels help buildings in motion keep their shape. Cross braces absorb compression and tensile forces by pushing back the […]

The coupling is normally the softest element in the drive line, literally – but by no means the weakest link of the chain. Its configuration plays a decisive role in the functional capability of the driving and driven machine and in the reliability and lifetime of the entire drive system. The optimum adjustment of the […]

Locking assemblies and locking elements come in so many sizes and different technical features that it can be overwhelming to find the right one for your application. That’s why we have developed our online calculation tool that makes it easy to select the right product. Locking assembly selection made easy The online calculator evaluates your […]

Function principle Shredders are constructed with multiple blades that shred the residual crops. In principle, they have a motor that rotates the motor shaft which is fixed with a pulley, and the shaft with blades is fixed with a reducer pulley, with the result that the shaft speed is doubled. When the shaft rotates at […]
