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.
Keyways can help prevent some couplings from slipping on the shaft in high torque situations. In this video we go over the feasibility and function of adding keyways to beam couplings.

Location: Owatonna, MN Question: Can you add keyways to a FSR style coupling? Answer: Yes, we can provided it's a straight bore coupling. We cannot do step bore beam couplings with keyways. The mechanical advantage of using a keyway is to prevent slippage on the shaft in high torque applications. Beam couplings are generally not recommended for use in high torque applications, which is why we don't offer them standard with keyways. We generally steer users towards one of our other types of servo couplings that better fits the application.
