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 zero-backlash jaw couplings and are a three-piece assembly with a balanced design comprised of two hubs and an elastomeric insert called "the spider". Users can combine clamp and set screw hubs with inch, metric, keyed, and keyless bores in sizes ranging from 1/8” to 1-1/4” and 3mm to 32mm for a high level of customizability. The polyurethane spider dampens impulse loads, minimizing shock to the motor and other sensitive components. They are available in three durometers to allow designers to fit the coupling to their application. All Ruland jaw couplings are carefully manufactured from select North American bar stock in our Massachusetts USA factory under strict controls using proprietary processes and RoHS3 and REACH compliant.
This section will allow you to select hubs to be used individually or as part of an assembly. Ruland jaw coupling hubs undergo a proprietary machining process to produce a curved jaw profile that press fits with the spider, assuring zero-backlash operation. The curved jaw profile concentrates the forces to the center of the spider’s limbs, improving the effectiveness of the elastomer material. Jaw couplings are considered fail safe because if the spider were to fail, the jaws of the two hubs interlock for direct power transmission, allowing the application to be safely shut down for maintenance.
This section will allow you to select spiders to be used individually or as part of an assembly. Ruland offers users the ability to tailor the performance of jaw couplings to match their application needs as spiders are available in three durometers, 85 Shore A for greatest dampening, 92 Shore A for balance of dampening and torsional stiffness, and 98 Shore A for a small amount of dampening and highest torsional stiffness. Stand offs on the spider limbs help installers maintain proper spacing between the two hubs, assuring electrical isolation and full angular misalignment capabilities. Spiders are designed to be the wear element of the coupling making replacement cost effective and simple while restoring full performance abilities to the coupling.
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. Stainless steel hubs and spiders with center holes are also available by request.
Ruland jaw couplings have superior strength, a precise fit, and a bright finish because the coupling hubs are machined from high-grade (type 2024 t351) aluminum bar stock.
Guaranteed zero-backlash operation due to the press fit of the hub and spider.
Speeds up to 8,000 RPMs with reduced vibrations due to our standard balanced design.
More than 20,000 customizable configurations with standard off-the-shelf parts where you choose from:
Clamp or set screw style hubs.
Inch or metric bores, with or without keyways.
Three spider durometers to tailor coupling performance to application needs.
