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.
This section will allow you to select spiders to be used individually or as part of an assembly. Ruland offers users the ability to tailor the performance of jaw couplings to match their application needs as spiders are available in three durometers, 85 Shore A for greatest dampening, 92 Shore A for balance of dampening and torsional stiffness, and 98 Shore A for a small amount of dampening and highest torsional stiffness. Stand offs on the spider limbs help installers maintain proper spacing between the two hubs, assuring electrical isolation and full angular misalignment capabilities. Spiders are designed to be the wear element of the coupling making replacement cost effective and simple while restoring full performance abilities to the coupling.

How to Order
Complete Coupling: Jaw couplings are an assembly of two hubs and one spider
Hubs: Choose two hubs in inch or metric in any style with the same outside diameter
Spider: Choose spider to match performance criteria. The spider must have the same outside diameter as both hubs.
