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 hubs to be used individually or as part of an assembly. Ruland manufactures oldham couplings in aluminum with an anodized finish for improved lubricity and stainless steel for corrosive applications. Hubs are manufactured with a proprietary machining process that creates a smooth interaction between the hub tenons and disk allowing for the longest service life in the industry. Torque transmission is achieved by mating the slots on the center disk to the drive tenons on each hub. Oldham couplings can help protect expensive machine components by acting as a torque limiter during overload. The disc breaks cleanly and does not allow for any power transmission. Oldham couplings are also electrically isolating since disks are non-conductive

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