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.
Ruland VMTT38-32-5/16-55-SSPS is a rubber bumper with a tapped hole. It has a 1.5" outside diameter, 5/16x18 tapped hole, 0.31" tapped hole depth, and 1.26" height. This rubber bumper is manufactured with FDA compliant materials for use in food processing, packaging, and medical equipment . It is often referred to as a sandwich mount or rubber buffer because it functions as shock or vibration isolator sandwiched between two machine components or surfaces. VMTT38-32-5/16-55-SSPS has a tapered (conical) shape for gentler accommodation of shock loads when compared to cylindrical types. It can be mounted to the system by passing it through an unthreaded hole and securing with a nut or threading it directly into tapped holes on the component it will be mounted to. The 304 stainless steel body combined with silicone rubber jacket makes for a bumper that can withstand temperatures up to 392F (200C) and has increased service life when compared to nitrile or natural rubber. VMTT38-32-5/16-55-SSPS has 55 Shore A hardness for a balance of rigidty and shock absorption. It is sourced from a premier partner, inventoried by Ruland, and RoHS3 compliant.
