Hubs and Spider Shown Assembled | (Each Component Sold Separately) |
Each hub includes a set screw (unless noted), which bites into your shaft to hold the coupling in place. Also known as Lovejoy® couplings, these three-piece couplings have a spider-shaped cushion between two hubs to reduce shock and handle minor shaft misalignment.
A complete coupling consists of two hubs and one spider, or two hubs, one split spider, and one retaining ring (all components sold separately). Split spiders are easier to install and replace than standard spiders because there’s no need for tools or removing your hubs. Twist-lock them in place using a retaining ring.
303 Stainless Steel—303 stainless steel hubs have excellent corrosion resistance.
Buna-N—Buna-N spiders provide good vibration damping and chemical resistance.
Hytrel—Hytrel spiders provide fair vibration damping and excellent chemical resistance.
Polyurethane Rubber—Polyurethane spiders and split spiders provide fair vibration damping and good chemical resistance.

Clamping Vibration-Damping Precision Flexible Shaft Couplings
 |  |
(Each Component Sold Separately) |
Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft. Tighten the clamping screws to secure. Good for precision motor and pump applications, the spider-shaped cushion reduces shock and compensates for minor shaft misalignment. Couplings allow zero backlash (no play).
A complete coupling consists of two hubs and one spider (each component sold separately). Hubs are lightweight, corrosion-resistant aluminum. Spiders are polyurethane for fair vibration damping and good chemical resistance.

Clamping Flexible Shaft Couplings
 |  |
Components of a Coupling Shown Assembled | (Each Component Sold Separately) |
Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft. Tighten the clamping screw to secure. Also known as Lovejoy® couplings, they have a spider-shaped cushion between two hubs to reduce shock and handle minor shaft misalignment.
A complete coupling consists of two hubs and one spider (each component sold separately). Hubs are aluminum for light weight and good corrosion resistance.

Machinable-Bore Flexible Shaft Couplings
 |  |
(Each Component Sold Separately) |
Customize the bore of these flexible couplings to align uncommon shaft sizes as well as shafts that have become undersized from wear or oversized from coatings. Also known as Lovejoy® couplings, these three-piece couplings have a spider-shaped cushion between two hubs to reduce shock and handle minor shaft misalignment. A complete coupling consists of two hubs and one spider (all components sold separately). Fasten to your shaft with set screws (not included), which bite into the shaft for a secure hold. If the spider fails, the hubs will lock together, giving you time to shut down your equipment to prevent component damage and replace the spider. These couplings do not need lubrication.

Splined-to-Keyed Flexible Shaft Couplings
 |  |
(Each Component Sold Separately) |
|
Diameter |
Connect splined shafts to keyed shafts. These couplings are commonly used to connect hydraulic pumps, compressors, and other heavy duty equipment, which often have splined shafts, to electric motors and other components that often have keyed shafts. They have a splined hub on one side and a keyed hub on the other. A spider cushion in the middle damps vibration, absorbs shock loads, and adjusts for misalignment. Because the hubs interlock with the spider, these couplings will continue to work even if the spider breaks or wears away. This fail-safe design gives you time to shut down your power source before damage occurs to other components. Lubrication is not required.
A complete coupling consists of two hubs and one spider. All components are sold separately.
