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.
Double friction bearing universal joints are designed for applications with a wide distance between shafts or applications in need of extreme angular misalignment accommodation up to 90°. They are comprised of two yokes, two blocks, and a center spacer joined by pins. Components are precision machined and ground to maintain tight tolerances, which allows for smooth operation with minimal backlash. Double universal joints are available in steel for high torque and stainless steel for increased corrosion resistance. Straight and step bore sizes including inch to metric are available from 3/16” to 1-1/2” and 5mm to 35mm. Boots can be added to protect the joints from contaminants in the operating environment. Boots can be packed with grease allowing for infinite life helping to reduce machine downtime.
