Quick-Disconnect (QD) Bushings


Clamp-On Shaft Mount	Machinable 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.

304 Stainless Steel—304 stainless steel bushings resist corrosion from washdowns and humidity, so they’re common in food-processing plants and other frequently-cleaned areas. You can machine the center of these bushings to fit the exact dimensions of your shaft.

Taper-Lock Bushings

Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws. They are for use with taper-lock sprockets of the same bushing trade number. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.

Dry-Running Sleeve Bearings

Made of naturally slippery plastic so you’ll never have to add lubricant. They’re ideal for clean environments where you need to prevent oil drips or graphite flakes. Compared to metal bearings, they are lighter and will never rust.

With no moving parts, sleeve bearings are the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.

Nylon—The most popular choice, nylon is wear resistant yet economical. Keep in mind, though, that it will swell and weaken when exposed to moisture.

Oil-Embedded Sleeve Bearings

Install and forget these self-lubricating bearings. All are made from porous metal and saturated with oil to reduce maintenance and downtime. A good all-around choice, they are used in everything from palm-sized fans in electronics to tire-sized pulleys. Although these bearings will work in most conditions, oil may drip away if temperatures get too high. Consider a graphite-lubricated bearing for higher temperatures or places where you can’t afford the mess. All are fabricated, lubricated, and inspected in the U.S.

With no moving parts, sleeve bearings are the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.

841 Bearing Bronze—A classic choice for a starter pick. Also known as SAE 841 bearings.

Synthetic Oil Base—A high-quality lubricant makes all the difference. Synthetic oil is less sensitive to temperature changes than mineral oil, so it won't get runny and leak away at higher temperatures.

Dry-Running Metal-Reinforced Plastic Thrust Bearings

Combine naturally slippery PTFE with the strength of metal. These bearings don't need lubricant, so there's no oil to maintain, drip off, or attract dust. Backed with steel, they're as strong as other all-metal thrust bearings. However, they're best for dry environments since moisture will cause the steel to rust.

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.

Set Screw Shaft Collars

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.

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

High-Torque Set Screw Flexible Shaft Couplings

Image of System. Front orientation. Contains Annotated, MultipleImages. Flexible Shaft Couplings. High-Torque Set Screw Flexible Shaft Couplings.

The thick split spider on these couplings takes on twice as much torque as standard split spiders, while a set screw holds the hubs in place on your shaft. Also known as jaw couplings, use them to connect motors to pumps, mixers, and other high-torque equipment. You don’t need to lubricate them.

For a complete coupling, you’ll need two hubs, one split spider, and a split spider cover (all sold separately).

Hubs attach to the end of your shaft.

Split spiders cushion between the two hubs to dampen vibration, reduce shocks, and handle shaft misalignment, extending the life of bearings, seals, and motors. You can replace them without having to remove the hubs or move your shaft and equipment around, which reduces the risk of needing to realign the shaft.

Split spider covers hold the spider in place.

Two-Piece Shaft Collars

For Round 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.

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

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

Black Anodized Aluminum—One-third the weight of steel and more corrosion resistant than unfinished aluminum.
