Mountable shaft collars with face holes are designed to mate directly with components such as sprockets, pulleys, and metallic plates. Ruland manufactures them with drilled holes for mounting flexibility or threaded holes for the most secure connection between the collar and mated component. They are offered in steel, aluminum, and 303 stainless steel in bore sizes ranging from 3/8” to 2” and 10mm to 50mm.
Clamp style universal joints improve over set screw style because they do not mar the shaft, offer infinite adjustability, and can be used on all shaft types. Ruland is the only North American supplier of clamp style universal joints and manufactures the clamp feature, bores, and keyways in our advanced manufacturing facility in Marlborough, MA USA. They are available in sizes from 1/4" to 1 1/4” in steel for high strength and stainless steel for corrosion resistance.
Ruland Controlflex couplings are a three-piece assembly with a balanced design comprised of two hubs joined to one or two center inserts called frogs. Clamp style hubs are manufactured with inch, metric, keyed, and keyless bores ranging from 1/8” to 1-1/2” and 3mm to 40mm for high customizability. The unique design of the frog concentrates forces onto its flexible limbs allowing for low bearing loads protecting sensitive small bearings in applications such as encoders or tachometers. Controlflex couplings are also electrically isolating since the hubs do not touch and frogs are made from acetal. They are manufactured by Schmidt-Kupplung in Germany and are RoHS3 compliant.
This section will allow you to select hubs to be used individually or as part of an assembly. Single insert controlflex hubs have high misalignment capabilities and fit in space restricted applications. They are manufactured in regular lengths for industry standard conformity and thin lengths for compact installations. Hubs are manufactured from lightweight aluminum and have a balanced design allowing for better performance at speeds up to 25,000 RPM.
This section will allow you to select hubs to be used individually or as part of an assembly. Double insert controlflex hubs offer higher torque and torsional stiffness capabilities. They are manufactured in regular lengths for industry standard conformity and thin lengths for compact installations. Hubs are manufactured from lightweight aluminum and have a balanced design allowing for better performance at speeds up to 25,000 RPM.
This section will allow you to select controlflex inserts to be used individually or as part of an assembly. The unique design of the insert allows them to remain rigid while flexing under misalignment conditions. Controlflex inserts have low restoring forces and help protective sensitive system components such as bearings in encoder type applications. They come standard with a center hole allowing shafts to be penetrated through the center if the application requires it. Controlflex inserts are manufactured from acetal and are designed as the wear element making replacement simple and cost effective.
This section will allow you to select the components to create a complete coupling. Please note that all orders ship unassembled. When you are ordering or downloading CAD all components are individual. They must be specified on any purchase order with a minimum of two part numbers. The combinations listed are a complete offering combining all available hubs and spiders. If the combination you are looking for is not available please use live chat or contact us at sales@ruland.com to determine if your combination can be manufactured.
Speeds up to 25,000 RPM with reduced vibrations due to a balanced design.
Reduced bearing loads, large-bore to small-bore ratio of 3.5:1, and compact designs make it the ideal encoder coupling.
Best overall misalignment capabilities in the Ruland product range.
More than 10,000 customizable configurations with standard off-the-shelf parts where you choose from:
Inch or metric bores, with or without keyways.
Regular or thin hub widths for long or short encoder shafts.
Single- or double-insert styles to tailor coupling performance to application needs.
