JAW COUPLINGS
Jaw type couplings come in the widest range of stock bore and keyway combinations available globally. Jaw couplings are highly reliable for light to heavy duty applications and don't require lubrication, whether you're repairing old couplings or installing new couplings to your industrial equipment, such as gearboxes, pumping equipment, blower motors, conveyor systems, or electrical motors. Jaw couplings are offered in 24 bore sizes ranging from 1/8" to 7". They are available in finished bore sizes featuring AGMA, SAE, and DIN standard keyways, or in plain bore styles without one. They are practically fail-safe even in the event that the elastomer insert breaks because there is no metal-on-metal contact. The components have exceptional damping qualities and are resistant to oil, grease, and dirt because of their extremely tight engineering. Standard type Jaw couplings are made up of two hubs that can be made of cast iron, stainless steel, aluminum, steel, sintered metal, and other materials, and an elastomer component known as a Spider insert that can be made of urethane, hytrel, bronze, or nitrile NBR SOX rubber. Each hub has an offset space between the jaws, allowing the hubs to connect easily through the appropriate spider insert and parallel opposite side hub. Their face design features a straight cut jaw shape. While we have a wide variety of stainless steel SS type jaw couplings, the AL and L Type jaw couplings are the most popular types we stock Following your selection of the jaw coupling hub type and bore size, Maxtran can help you choose the appropriate Spider insert material and type. Jaw couplings, spider inserts are available in Solid Centers and Open Centers. Numerous colors and materials, such as urethane, NBR nitrile rubber, hytrel, bronze, and stainless steel, are available for your application. For jaw coupling assemblies of all sizes, Maxtran® carries thousands of AL, L, H, BR, and other varieties of Spider inserts in stock. For all of your jaw coupling accessories and parts, rely on Maxtran.
