Ringfeder offers many types of Locking Assemblies. These friction-locked shaft-hub connections precisely fasten all types of hubs. They can also bridge relatively large fit clearances and are easy to install, adjust and remove. When browsing the Ringfeder product page, one might notice that some of the standard Locking Assemblies come in different models. Here, Ringfeder […]

Ringfeder on the right coupling for heavy-duty hoist applications
Cranes and hoists are only as good as their couplings, which are 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 manufacturing process to grind to a halt. This kind of downtime is not welcome – especially […]
How locking assemblies enable HVLS fan applications to keep their cool
High-volume, low-speed (HVLS) fans play an important role in many applications, from agricultural processing to warehousing. These ceiling-mounted units can move large amounts of air due to their size, which generally exceeds 7 feet in diameter. In terms of their design, these fans have a geared motor that connects to a forged hub, which includes […]
Ringfeder locking assemblies for bending loads
Uncompromising performance under extreme loads with specially developed RINGFEDER Locking Assemblies for Bending Loads: One of the most challenging applications for our locking devices are belt drums which are used, e.g., in mostly large-scale conveyor systems for iron or copper ore, coal, and other mineral resources. The shaft-hub connections used between the drum shaft and […]
Ringfeder shrink discs
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 creating […]
Ringfeder releases GWE 5117 servo-coupling for hollow shaft connections
RINGFEDER has recently released its GWE 5117 series of elastomer jaw servo-couplings, featuring a new hub design. With its partially slit hub located directly under the jaws and two screw clamps, this model eliminates radial loads on the shaft and achieves uniform power transmission. This hub design also prevents premature wear and system failure. Designed […]
Ringfeder locking assemblies for securing rotors in impact crushers
Apart from transmitting the rotor torque, locking assemblies installed in crushers are subjected to further loads such as bending moments and radial impacts. The factors which have to be considered for these applications are briefly described in this article. Please also watch the video and learn how modern impact crushers work. Function principle Impact crushers […]
Ringfeder’s two- and three-piece shrink discs
Depending on your application, you may need a two- or three-piece Shrink Disc design to create a secure shaft-hub connection. Let’s explore some of their key similarities and differences to help you select the right one. General Shrink Disc Design A modern method for creating a mechanical shrink fit, Shrink Discs offer an even distribution […]
