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.
Location: Des Moines, IA Question: Can a Ruland shaft collar be welded? Answer: Yes. Any of our standard steel collars can be welded. We use 1215 lead-free steel as our standard material. The lead-free characteristic is a benefit when welding and not common for other collar manufacturers that typically use 12L14. The primary drawback to 1215 is that it's not as easy to weld as other steels such as 1018. We generally recommend that the use take sand paper or some other abrasive to remove the black oxide coating at the weld point for a better surface. Mountable shaft collars are made with flats on the bottom and the top of the OD, which is a benefit if you are going to be welding the collar to a hinge or a plate.
