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 rigid couplings are commonly used in food processing equipment for torque transmission or shaft to shaft connections. They are zero-backlash and have high torsional stiffness and torque capabilities making them an ideal solution for food processing equipment where motors are connected to a gearboxes, lead or ball screws, or conveyors. Ruland is the only manufacturer that precision hones straight bore rigid couplings to ensure bores are collinear for precise fit and greater torque transmission ability. Proprietary Nypatch® anti-vibration coating is used on clamp style hardware that allows for even seating of the screw, repeated screw installations, and prevents galling, which is especially useful in food processing applications requiring stainless steel.
Ruland manufactures rigid couplings in set screw and clamp screw types. Set screw styles are best suited for lighter duty applications where vibration is limited to prevent hardware from coming loose during operation. Clamp style rigid couplings wrap evenly around the shaft for precise fit and increase torque capabilities. Two-piece styles can be serviced in-place and have a balanced design for reduced vibration. Ruland manufactures rigid couplings in 1215 lead-free steel with a black oxide finish for high torque, lightweight 2024 aluminum for low inertia, and 303 stainless steel for increased corrosion resistance in bore sizes ranging from 1/8” (3mm) to 2” (50mm).
