Lovejoy 56512 Size RRS090 Radially Removable Spacer Coupling Hub, Inch, 0.5" Bore, 2.11" OD, 0.125" x 0.063" Keyway

 Ean: 0685144565129   |    PartNumber: 68514456512   |   Asin: B004QWZRDS

This Lovejoy radially removable spacer (RRSC) coupling hub replaces hubs on Lovejoy RRSC type jaw style flexible couplings. This hub transfers shock and misalignment from the shaft to the center element of the coupling assembly for reduced wear on the shaft assembly and has tines that mesh with the spacer assembly to lock the hub into 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.

Features

  • For use with Lovejoy RRSC type Jaw style flexible coupling assembly (sold separately)
  • Transfers shock and misalignment to the center element of the coupling assembly for reduced wear on the shaft assembly
  • Tines for locking hub to spacer assembly

Lovejoy SC375 Rigid Sleeve Coupling Coupling, 3/8" Bore, No Keyway, With Setscrew, 0.75" Outer Diameter, 1.00 Overall Length

Model: 68514414326   |    Mpn: 68514414326   |    Ean: 0685144143266   |    PartNumber: 68514414326   |   Asin: B004S2TCXW

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 other transmission and mechanical power products. The company, founded in 1900, is headquartered in Downers Grove, IL.

Features

  • For use in joining two shafts where flexibility is not required
  • Aluminum for light weight and low momentum
  • Does not accommodate angular, axial, or parallel misalignment
  • Bore diameters of up to 1.375 inches
  • Set screw and key way for secure attachment to shaft
