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.

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.

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.

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.

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

Carbon Steel—Strong and easy to machine. Use in dry environments, since moisture will cause steel to rust.

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

Set Screw Two-Piece Shaft Collars

Attach these traditional collars anywhere along a shaft when other components are already installed or you can't access the ends. Their set screw digs into the shaft for a tight, permanent hold, but one that leaves a gouge. For maximum holding power, make sure the set screw is harder than the shaft.

Two-Piece Shaft Collars with Wrench Flats

When adjusting or troubleshooting your drive shaft, turn these collars with a wrench to avoid marring or gouging the surface. To install, snap the two pieces together anywhere along the shaft, which helps when other components are attached or you can't access the ends.

Slide these traditional collars from one end of the shaft and tighten the set screw. They dig into the shaft for a secure hold, but one that leaves a gouge. For maximum holding power, make sure the set screw is harder than the shaft.

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

Blue Passivated Zinc-Plated Carbon Steel—Withstand moisture and mild chemicals better than standard zinc-plated-steel collars. The blue passivated finish makes it easy to identify metric collars at a glance.

Carbon Steel—Strong and easy to machine. Use in dry environments, since moisture will cause steel to rust.
