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 bellows couplings are comprised of two anodized aluminum and a stainless steel bellows creating a low inertia zero-backlash coupling that is well suited for speeds up to 10,000 RPM. The thin wall of the bellows allows the coupling to remain flexible under misalignment conditions while maintaining rigidity under torsional loads. They are the most torsionally stiff flexible coupling Ruland offers making them a good fit for encoders that require the highest level of resolution. When designers select a bellows coupling for an encoder they must control for misalignment. While bellows couplings to accommodate all forms of misalignment, they are not as flexible as beam or controlflex types. Bellows couplings are manufactured in our Marlborough, Massachusetts factory with bore sizes ranging from 1/8” to 1” or 3mm to 25mm.
