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.
Align the coupling on the two shafts to be connected.
Tighten the Nypatch® clamp screws in two stages. Starting with the inside screws, tighten to half of the recommended seating torque. Repeat for the outside screws, again tightening to half of the recommended seating torque.
Be sure to maintain the gap between the two halves of the coupling on two-piece styles.
Align the bores of the Controlflex coupling hubs on the shafts that are to be joined and determine if the misalignment parameters are within the limits of the coupling. (Select Hub for misalignment parameters.)
Rotate the hubs on the shaft so the drive pins are 90° from each other.
Place one hub at the end of the shaft. Tighten the clamp screw to the recommended seating torque.
Place an insert(s) with the standoffs facing the hub over the pins of the hub that was just installed.
Align the drive pins on the second hub to match the holes in the insert(s).
