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.
SHIM21/33-A-KIT is a pack of aluminum shims designed to aid in the installation of Ruland manufactured zero-backlash jaw and oldham couplings. It comes with 32 layers that can be peeled off with a knife or other sharp object. Each layer is 1.813" (46.01mm) long, 0.378" (9.6mm) wide, and .002" (.05mm) thick and made of 5052 aluminum for corrosion resistance, rigidity, and durability. It is used during the installation of Ruland zero-backlash jaw and oldham couplings with an outer diameter identifier of 21/33. SHIM21/33-A-KIT ensures proper spacing between the hubs and insert allowing the coupling to reach its full misalignment capabilities. The shim is simply slid into the space between the hub and insert while the user is tightening coupling hardware to its recommended seating torque and then removed once assembly is complete. SHIM21/33-A-KIT is manufactured by Georg Martin GmbH in Germany and RoHS3 and REACH compliant.
