"Marketplace since 2012"


Since entering the power transmission marketplace in the 1920s, Lovejoy has emerged as an international market leader. Today, the Lovejoy couplings brand is recognized around the world as the premier supplier of flexible shaft couplings and other power transmission components. Lovejoy coupling Lovejoy couplings are known for their premium build qaulity and high durability.
Jaw Coupling


  • Quick-Flex Couplings When your equipment operates in harsh environments, you need coupling products you can count on. QUICK FLEX elastomeric couplings are designed to withstand those harsh conditions, yet need minimal maintenance. They’re easy-to-install and require no lubrication. With a lifespan that can match that of your equipment, QUICK FLEX couplings can keep your overall cost of ownership competitively low.
  • Hercuflex Couplings

HercuFlex® offers increased nominal torque, larger maximum bore size and longer service life. Despite the advanced nature of these improvements, the HercuFlex Gear Coupling still utilizes the standard AGMA flange interface to ensure field interchangeability.
In addition to unequaled bore and torque capacity while maintaining compliance with standard AGMA flange interfaces

  • S-Flex Couplings

The simple design of the S–Flex Endurance coupling ensures ease of assembly and reliable performance. No special tools are needed for installation or removal. The S–Flex Endurance couplings can be used in a wide variety of applications.

The S–Flex Endurance coupling design is comprised of three parts. Two flanges with internal teeth engage an elastomeric flexible sleeve with external teeth. Each flange is attached to the respective shaft of the driver and driven and torque is transmitted across the flanges through the sleeve.

  • RunRight Tensioners

RunRight® rubber suspension units are designed for use in countless applications that require a torsional spring feature with angles of operation of +/- 30˚. When using these units in an application, the torsional force that is applied as well as the radial, axial and/or cardanic forces need to be taken into consideration when sizing a unit.

  • Jaw Type Couplings

The Jaw Type couplings from Lovejoy are offered in the industry’s largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications.

  • Grid Couplings

The Lovejoy Grid coupling reduces vibration by as much as 30%, and cushions shock loads to safeguard your driving and driven equipment. The flexible nature of the spring-like grid absorbs impact energy by spreading it out over time, thus reducing the magnitude of the peak loads. This is possible because of the progressive contact that occurs between the curved profile of the hub teeth and the flexible grid. Therefore, as the load increases, more of the tooth comes into contact with the grid, thus supplying superior protection and supreme performance.

  • Torsional Couplings

Lovejoy offers a wide range of torsional couplings engineered to solve torsional vibration problems found in diesel engine driven equipment and other applications where torsional vibrations are prevalent. These include all internal combustion engines, reciprocating pumps and compressors, as well as variable frequency drives (VFD).

  • Disc Couplings

Lovejoy takes great pride in being able to offer a wide variety of superior disc coupling products in models designed to meet the application needs of today’s worldwide power transmission market.

Using advanced design techniques, implementation of Finite Element Analysis, and extensive testing of materials, Lovejoy has developed an innovative disc pack profile

  • Jaw In-Shear Couplings

The Jaw In-Shear Coupling is non-fail safe, and thus the coupling acts as a fuse to prevent equipment damage in the event of torque overloads. Instead of the spider being compressed in between the interlocked jaws of each hub, our In-Shear coupling has the hubs drawn apart with the jaws aligned axially. The wider spider is then in a shear-plane.

  • Curved Jaw Couplings

As the premier manufacturer of couplings in the world, Lovejoy offers the full line of the European standard jaw coupling. Supplied and in use around the world, Lovejoy’s curved jaw couplings can meet your every curved jaw need.

  • Gear Type Couplings

Lovejoy offers a variety of designs and models in its gear coupling family. From standard, off-the-shelf stock to new, high speed, special designs-Lovejoy can satisfy your gear coupling needs.

  • High Performance Gear Couplings

Lovejoy High Speed and Engineered Special Gear Couplings satisfy a specific engineering need for custom coupling designs that require additional engineering. While standard components do exist, the unique requirements of individual applications will customize a coupling design. (For stock gear couplings, please see our Gear Couplings product page.

  • Lovejoy Universal Joints

Lovejoy has been manufacturing industrial universal joints for over 50 years. Our industrial universal joint product line is well established and provides you with a wide range of standard and specialized products. The shape of the yoke is a special feature which results in exceptionally high strength, yet allows full, free movement of the joint. This accounts for the high horsepower capacity at high speeds.

  • Rigid Couplings

When you want the strength of a rigid coupling at cast iron prices, choose Lovejoy rigid compression couplings. The  design of our rigid compression couplings make them well suited for the toughest applications.  Rigid compression couplings give you greater reliability than similarly priced cast iron couplings. These compression couplings are made from cast steel and powder-coated to resist corrosion. Easy to install and remove, they provide a strong, durable connection between two shafts of the same size.
