Lovejoy 11075 Size L-AL 090-095 Open Center Type Jaw Coupling Elastomer, Urethane, 7/8" Open Center, 2.12" OD, 0.44" Length, 291 in-lbs Nominal Torque

Model: LOV L/AL090/095 SPDR URE   |    Mpn: 68514411075   |    Ean: 0685144110756   |    PartNumber: 68514411075   |   Asin: B003HIX2HU

This Lovejoy jaw coupling open center type elastomer (center element) replaces the open center type elastomer on Lovejoy L type jaw style flexible couplings and is made of urethane for transferring and absorbing shock load. Materially it has a high flexion capacity to compensate for severe shaft misalignment, and its six prong "spider" shape also contributes to its flexibility while facilitating its capacity to remain locked in place. Lovejoy jaw style couplings are suitable for use in various industrial power transmission applications such as compressors, blowers, pumps, conveyors, mixers, and gear boxes, among others.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other. Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts. Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another. Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Lovejoy manufactures flexible couplings, universal joints, variable speed drives and various other transmission and mechanical power products. Their products meet the standards of the International Organization for Standardization (ISO), the Deutsches Institut f r Normung (DIN), the American National Standards Institute (ANSI), the American Gear Manufacturers Association (AGMA), the Society of Automotive Engineers (SAE) and Japanese Industrial Standards (JIS) for quality assurance. The company, founded in 1900, is based in Downers Grove, IL.

Lovejoy 35570 Size 7JE Solid Design S-Flex Coupling Sleeve, EPDM Rubber, 4.34" OD, 2.19" Elastomer Length, 725 in-lbs Nominal Torque

Model: LOV 7JE SLEEVE   |    Mpn: 68514435570   |    Ean: 0685144355706   |    PartNumber: 68514435570   |   Asin: B003LVYX6C

This Lovejoy solid design S-Flex coupling sleeve is for use on the Lovejoy S-Flex series flexible coupling assembly and is made of an ethylene propylene diene monomer (EPDM) synthetic rubber for transferring and absorbing shock load. It is a single, solid piece for applications where the coupled shafts are not difficult to separate, and its teeth help to distribute torsional load across itself and the flanges, reducing wear and extending service life. Lovejoy S-Flex series flexible couplings are suitable for use in applications requiring torsional flexibility and the capacity to withstand shock loads and vibration, including blowers, compressors, conveyors, dredges, feeders, generators, mills, and presses, among others.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other.

This Lovejoy solid type jaw coupling elastomer spider replaces solid center elastomers on Lovejoy jaw style flexible coupling assemblies and is made of Nitrile rubber for transferring and absorbing shock load. The solid center design keeps the shafts of the driver and driven equipment separate by a standard gap. It can operate in temperatures ranging from -40 to 212 degrees F (-40 to 100 degrees C). Lovejoy jaw style couplings are a type of flexible coupling suitable for use in various industrial power transmission applications such as compressors, blowers, pumps, conveyors, mixers, and gear boxes, among others.
