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.

Jaw coupling spiders do not all share the same properties but what exactly do the different colors represent?
Transcript
Location: Waco, TX Question: Do the spider colors represent anything? Answer: Yes, they definitely do. We dye the spiders so users and we Rulanders can differentiate between the durometer, or the hardness, of the spider. As you can see with the undyed spider in my hand, there's no quick visual way to differentiate it from any other spider. We offer spiders in 3 durometers which allows users to tailor the coupling's performance to the needs of their application. The dye is critical for us when we go to pick order to know we have picked the right one and for you, when you receive it, to know you've received the right one. The red spider is 98 Shore A hardness, the yellow spider is 92 Shore A hardness, and the blue spider is 85 Shore A hardness.
