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.
Threaded shaft collars share the same performance and benefits of their round bore counterparts, while providing additional features. Threaded collars have higher axial holding power than round bore collars, while offering easier installation and adjustment than solid ring locking devices. A diverse list of acme, right hand, and left hand thread sizes and pitches are offered. Ruland double taps each threaded collar to ensure precise and burr-free threads to allow for easy installation and removal, proper fit, and extended shaft life. Threaded shaft collars are manufactured in 1215 lead-free steel with a black oxide finish and 303 stainless steel. Bore sizes range from 1/8" to 2-1/4" and 4mm to 30mm.
