LoveJoy

CJ Jaw Couplings

Lovejoy CJ type curved jaw couplings provide improved torsional softness compared to standard jaw couplings. These couplings are easy to install and are failsafe in that they’ll still transfer torque even if the elastomer fails. Four different elastomers are available to best suit the application.

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

Continuous Sleeve Gear Couplings

Lovejoy continuous sleeve couplings are simple and affordable. 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.

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

Flanged Sleeve Gear Couplings

Lovejoy flanged sleeve gear couplings feature the patented Vari-Crown tooth form for long life. They can be used in horizontal or vertical applications and have minimum backlash. Exposed and shrouded bolt models are available.

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

Horizontal Split Grid Couplings

Lovejoy horizontally split grid couplings allow easy access to the grid and are great for tight spaces. These couplings cushion shock loads and can dampen vibration by up to 30%.

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

L/AL Jaw Couplings

Lovejoy L and AL type jaw couplings require no lubrication and are very reliable. Lovejoy offers the largest variety of stock bore/keyway combinations in the industry. AL couplings use aluminum hubs for lighter weight and corrosion protection.

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

SLD Locking Devices

Lovejoy shaft locking devices (SLD) connect hubs solidly to shafts using a keyless mechanical interference fit. They use screw tension to expand the SLD to fill the gap between hub and shaft. This makes them easy to install and remove, and allows hubs to be more accurately positioned on the shaft.

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

SU Disc Couplings

Lovejoy SU type industrial disc couplings consist of two hubs and one disc pack, so it’s only suitable for angular and axial misalignment. No lubrication or maintenance is required, and there are no wear parts, so infinite life is possible when properly aligned.

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

SX Disc Couplings

Lovejoy SX type industrial disc couplings are similar to type SU, but have two disc packs. This gives two flex planes, allowing them to also accommodate parallel misalignment. These couplings are torsionally rigid and transfer torque without backlash.

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