Set Screw Flexible Shaft Couplings


Hubs, Split Spider, and Retaining Ring Shown Assembled	(Each Component Sold Separately)

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.

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.

High-Torque Flexible Shaft Couplings


	(Each Component Sold Separately)

With a rugged roller-chain design, these couplings provide excellent torque and angular misalignment capacities. Lubrication is required. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.

A complete coupling consists of two hubs and one roller chain (each component sold separately). Complete couplings meet ANSI B29.23M-1995.

Optional covers retain grease lubrication and provide protection from abrasion and corrosion.

High-Speed Vibration-Damping Flexible Shaft Couplings


	(Each Component Sold Separately)

Use these gear-shaped couplings for high-speed and high-torque applications. A rubber center allows flexing so couplings can take on multiple types of misalignment while damping vibration and shock. With no metal-to-metal contact, there’s no need for lubrication. Fasten to your shafts by tightening the set screws, which bite into the shaft to hold it.

A complete coupling consists of two hubs and one center (each component sold separately).

Hubs have a keyway, except hubs for 1⁄4" and 3⁄8" shaft dia. do not have a keyway.

Two-Piece Shaft Collars

For Round Shafts

For Keyed Shafts

Attach these collars anywhere along your shaft, which helps when other components are already installed or you can't access the end. They clamp firmly and evenly without marring the shaft, so you can reposition or remove collars later.

Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.

Zinc-Plated Carbon Steel—A step up from plain carbon steel collars, these withstand occasional exposure to moisture.

Chrome-Plated Carbon Steel—Resist moisture and mild cleaning solutions better than zinc-plated collars.

303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.

316 Stainless Steel—More corrosion resistant than 303 stainless steel collars. These collars withstand salt water and harsh chemicals, such as bleach, chlorine, and phosphoric acid.

Aluminum—One-third the weight of steel and corrosion resistant.

Bearing Adapter Sleeves

Make up for imperfections and gaps between your bearing and shaft for a tight fit. These bearing adapter sleeves are the most common way to mount a bearing with a tapered bore onto a cylindrical seat. They work with both straight and stepped shafts. Secure using the included lock nut.

Quick-Disconnect (QD) Bushings


Clamp-On Shaft Mount

The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) sprockets and pulleys of the same bushing trade number. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
