Lovejoy's extensive catalogue comprises rubber suspensions, coupling hubs, V-belt pulleys, sprockets, coupling spiders, universal joints, shaft locking devices and variable speed drives. Lovejoy couplings are designed to transmit torque and rotation between two shafts for accommodating shaft misalignment. These couplings dampen shock and vibrations to prevent damage to components. Lovejoy couplings feature two hubs and an insert (known as a spider) that fits between the hubs. Spiders offer high load capacity while maintaining a damping effect on vibration and thermal conductivity. We offer an entire catalogue of Lovejoy couplings, including QUICK FLEX, curved jaw, jaw in shear, S-Flex Endurance, HercuFlex gear, torsional and disc style couplings. The brand's hydraulic reservoirs are designed for storing excess hydraulic fluid during agricultural & chemical processing applications. They feature cast aluminium construction with steel mesh & cover for durability & protection against contaminants. They have Buna-N gaskets for a leak-tight seal and aluminium finish for complete protection against abrasive fluids, chemicals & harsh industrial environments.
Lovejoy coupling spiders are useful where shafts and driven equipment need to be kept partitioned by a standard gap. These fail-safe Lovejoy spiders are used with L-type keyway hubs to prevent relative movement or extremely close (near touching) shaft separation, making them resistant to dirt, sand, oil, moisture & grease. These closed-centre units have a robust design and are desirable for high-speed applications. Lovejoy coupling hubs are available in various shaft connection options, such as keyway / set screw style, clamp style and an integrated shrink disc style on Raptor Supplies.

With QUICK FLEX couplings, you can significantly reduce maintenance, downtime and total cost of ownership for couplings. These Lovejoy couplings can transmit more torque than gears, grids or elastomeric couplings. Unlike rotating equipment, they are easy to install, do not require oil, and last long...
S-FLEX ENDURANCE couplings are designed to transmit uniform loads, absorb shock, dampen vibration, and accommodate misalignments up to 1 degree. They have a three sleeve design and are made from high quality EPDM, enabling these couplings to adapt to conditions such as extreme shock loads or high vi...
HERCUFLEX gear couplings are designed using the latest Finite Element Analysis (FEA) technology. These couplings are equipped with unequalled bore sizes, ranging from 7/16 to 44 inches, and torque capacity up to 54000000 inch-lb. These Lovejoy couplings are designed with a unique seal that makes the...
RunRight rubber suspension units are designed for applications that require torsional springs, with operating angles between +/-30 degrees. These Lovejoy couplings are manufactured with Tensys 10 elastic inserts having a high content of natural rubber, to offer high chemical resistance, shape reten...
A Lovejoy coupling is user-assembled by combining two coupling hubs and one spider. Users should use safety equipment, tightening tools and dial indicators for ensuring correct installation, efficient operation & user safety. Hubs & spiders of the same series should be used together and should have the necessary parameters according to Lovejoy's installation / operating manual.
For example, if users want to build & install a CJ Series coupling, they can follow the steps given below:
...
Lovejoy spiders are colour coded on the basis of shore hardness, torque capacity and material. Each shore hardness level of a Lovejoy coupling spider corresponds to separate torque capacity, damping and chemical resistance, ideal for different applications.
Following is the colour coded table of CJ Series spiders based on their shore hard...
The Timken Company (a world leader in tapered roller bearings) owns Lovejoy Inc., which is a leading manufacturer of industrial couplings and universal joints.
Lovejoy Inc. is headquartered at Downers Grove, Illinois, USA.Their manufacturing operations in the USA are undertaken at plants in Downers Grove, Illinois and South Haven, Michigan.
Selected models of Lovejoy couplings have a keyway - a slot cut out from the mating part of the couplings. These slots fit in the keys attached to shafts or other mated tools. The use of keys leads to improved torque & slippage prevention. It also results in reduced losses due to vibration & backlash (degree of free movement between two rotating, mating parts).
Grid style couplings are used for a wide variety of mining & industrial applications, but they can cause lots of hassle & downtime. These grid couplings require frequent lubrication and maintenance to prevent wear & tear. They are hard to remove from shafts, for maintenance or replacement. They also cause lubricant leakage, which can cause accidents or injuries. Disc couplings, on the other hand, do not need lubrication and can handle the desired torque & misalignment requirements, all while being resistant to harsh environments. These disc couplings also can be maintained, inspected & replaced easily, as they have no wearable parts.
Lovejoy couplings are certified to AGMA (American Gear Manufacturers Association), API (American Petroleum Institute) and ANSI (American National Standards Institute) standards. Lovejoy Inc. is also ISO 9001:2015 certified for maintaining superior quality while manufacturing couplings.
Lovejoy couplings provide vibration damping, shock absorption, misalignment tolerance and ease of installation.
Choosing the right coupling depends on factors like the type of machinery, torque requirements, shaft sizes, misalignment and environmental conditions.
Yes, Lovejoy clamp-style couplings are suitable for electric motors. They protect shaft support bearings against the destructive thrust and radial load due to axial motion and misalignment, respectively.
