Available products are specially designed to offer you a diverse array of solutions for your mechanical equipment applications. These are reliable options for upgrading current machinery and optimizing new equipment. Using products that are best suited for your needs can directly improve your bottom line. The right parts can reduce machinery downtime and limit needed repairs throughout the lifetime of your equipment. Lovejoy components are made with precision, to give you a final product that you can depend on.

Since entering the power transmission marketplace in the 1920s, Lovejoy has emerged as an international market leader. They created the industry standard jaw-style coupling in 1927 and were the first to incorporate rubber-in-compression as a power transmission concept. Today, Lovejoy is recognized around the world as the premier supplier of flexible shaft couplings and other high-quality power transmission components. They offer a wide range of couplings, such as jaw (L, AL, CJ), gear (F and C), grid, disc (SU and SX), and torsional couplings, as well as keyless shaft locking devices.

Lovejoy’s products cater to industries such as steel, pulp and paper, power generation, food processing, mining and construction. No matter what your application, Clutch Engineering will carefully analyze your product requirements and provide the optimal coupling solution.

L/AL Jaw Couplings

Lovejoy L and AL type jaw couplings are specially designed coupling products available from Clutch Engineering. AL couplings feature aluminum hubs to achieve a lighter weight and enhanced corrosion protection. The AL Type coupling is made from two hubs and one spider. Lovejoy offers the largest variety of stock bore/keyway combinations in the industry. These jaw couplings require no lubrication and are very reliable under various conditions. AL Type couplings use the same spiders as L Type couplings, except AL150 which has four jaws instead of three.

Torque range: 3.5 to 12,500 lb-in (0.4 to 1,412 Nm)
Typical applications: Pumps, gear boxes, compressors, blowers, mixers, conveyors

CJ Jaw Couplings

Clutch Engineering offers these well-made Lovejoy CJ type curved jaw couplings for applications such as pumps, gear boxes, compressors, mixers, and more. Lovejoy CJ jaw couplings are a mechanical solution with improved torsional softness, compared to standard jaw couplings. Urethane spiders integrated into the product are designed to provide high abrasion resistance and elasticity, along with good damping characteristics. These couplings are easy to install and they can be used in a fail-safe capacity, due to their ability to continue a transfer of torque in the event of the elastomer failing. There are four different elastomers available, to best fit the needs of your system. The spiders are available in a variety of shore hardnesses, each providing a different level of torque capacity, damping, and chemical resistance.

Torque range: 35 to 309,750 lb-in (4 to 34,996 Nm)
Typical applications: Pumps, gear boxes, compressors, blowers and fans, mixers, conveyors, generator sets

Flanged Sleeve Gear Couplings

Clutch Engineering offers Lovejoy flanged sleeve gear couplings that feature the patented Vari-Crown tooth form. These flanged sleeve gear couplings can be used effectively in horizontal or vertical applications and they also deliver minimum backlash. Exposed and shrouded bolt models are available to meet the needs of your systems. The specialized Vari-Crown tooth form leads to long life in the coupling, which improves your bottom line by supporting longer machine uptime and less maintenance costs. The F Type coupling is made of two flex hubs, two sleeves and one accessory kit. This advanced coupling is supplied with exposed bolts as standard. Shrouded bolts are available upon request through size 5.5.

Torque range: 7,600 to 1,827,000 lb-in (850 to 206,400 Nm)
Typical applications: Steel mills, paper mills, pumps, logging machinery

Continuous Sleeve Gear Couplings

Clutch Engineering offers Lovejoy continuous sleeve couplings for use with industrial applications such as mills, pumps, and many other machinery use cases. These products are are simple and highly-compatible with applications requiring horizontal and vertical orientation. They are also affordable, to support your bottom line as you install and enhance critical machinery. The patented BUNA N seal design keeps lubricant in and contaminants out. Standard C type couplings are available, as well as special variations such as mill motor, floating shaft, drop-out spacer, and shear pin types. Designs are appropriate for many applications that include full-flex, flex-rigid, mill-motor, disengagement, sliding hubs, shear pin, floating shaft, and spacers.

Torque range: 2,500 to 2,520,000 lb-in (300 to 284,700 Nm)
Typical applications: Steel mills, paper mills, pumps, logging machinery

SU Disc Couplings

Clutch Engineering offers Lovejoy SU type industrial disc couplings for use with industrial fans, compressors, hoists, and more. These couplings consist of two hubs and one disc pack, they are only suitable for angular and axial misalignment. Additionally, these are designed to function without ever needing maintenance or lubrication. These products use are no wear parts, and infinite life is possible with correct alignment. These specialized parts can also be heated up to high temperatures, usually 450º F to 600º F (235º C to 315º C). Lovejoy disc coupling hubs are shipped with Interference Fit bores, unless otherwise specified.

Torque range: 2,100 to 650,500 lb-in (240 to 73,500 Nm)
Typical applications: Blowers, fans, compressors, hoists, conveyors

SX Disc Couplings

Clutch Engineering provides high-quality Lovejoy SX type industrial disc couplings for various industrial applications such as blowers, fans, compressors, and more. These specially designed parts have similarities to type SU, but they have two disc packs. These products can be found in use with mechanical systems for industrial blowers, fans, compressors, and many more applications. An advantage of these couplings is that they feature two flex planes, which allows them to accommodate parallel misalignment. These couplings are also torsionally rigid and they are able to transfer torque without backlash. For all Lovejoy disc coupling hubs with taper bores and taper bores with keyways, Lovejoy manufactures these hubs with bores using tolerances and specifications that are supplied by the customer.

Torque range: 2,100 to 1,947,000 lb-in (240 to 220,000 Nm)
Typical applications: Blowers, fans, compressors, hoists, conveyors

Horizontal Split Grid Couplings

Available from Clutch Engineering, Lovejoy horizontally split grid couplings can be integrated into various systems, while allowing easy access to the grid. The gasket and seal kit consists of 2- seals and the appropriate gasket(s). These couplings are a fantastic option in many systems where parts are being installed within small and tight spaces. These advanced couplings are also able to cushion shock loads and dampen vibration by up to 30%. Couplings from size 1020 to 1090 are supplied with coupling grease.

Torque range: 460 to 1,650,000 lb-in (52 to 186,417 Nm)
Typical applications: Compressors, pumps, extruders, conveyors

SLD Locking Devices

Clutch Engineering offers Lovejoy shaft locking devices (SLD) that can connect hubs solidly to shafts in applications such as sheaves, sprockets, drive shafts, and more. These specially manufactured parts use a keyless mechanical interference fit. They also feature adjustable screw tension to expand the SLD to fill the gap between hub and shaft as needed. This option makes them easy to install and remove, and importantly, allows hubs to be positioned on the shaft accurately and effectively. The Lovejoy SLD 900 Shaft Locking Device is engineered to provide an efficient, high capacity, zero backlash, hub-to-shaft connection using a specialized mechanical interference fit.

Torque range: 1.73 to 565,563 lb-ft (2.3 to 766,800 Nm)
Typical applications: Sheaves, sprockets, gears, driveshafts, coupling mounting
