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.

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.

Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads. When you tighten the included clamping screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.

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.

Infused with food-grade oil, these bearings are safe for incidental contact with food. The oil is odorless, colorless, and tasteless, so they're common on food production and packaging lines. You can install and forget them since their porous surface releases oil over time. All are fabricated, lubricated, and inspected in the U.S.

If you need a bearing rated for direct contact with food, consider dry-running thrust bearings for food and beverage.

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.

Our slipperiest metal thrust bearings glide on machines with frequent starts and stops, such as conveyors. Their oil contains nonstick PTFE particles that reduce wear and heat, extending the life of your equipment. All are fabricated, lubricated, and inspected in the U.S.

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.

Able to handle high twisting forces as well as misalignment, these couplings are good for high-performance servomotor applications. Couplings are aluminum and stainless steel for corrosion resistance and allow zero backlash (no play). They grip evenly around your shaft for a strong hold without marring the shaft. Tighten the clamping screws to secure.

Connect shafts and ball screws to high-speed servomotors and stepper motors—these shaft couplings handle four times more speed than standard servomotor couplings. They’re often found on high-torque motors that frequently start and stop, such as those used with packaging machines, press brakes, and semiconductor manufacturing equipment.

With aluminum hubs joined by a flexible fluoroelastomer or Buna-N core, these shaft couplings dampen vibration and adjust for misalignment. When machines accelerate and decelerate quickly, these couplings remain stiff to maintain accuracy and repeatability, which prevents equipment from moving out of place. They also resist backlash, meaning all of the turning force from the motor is passed on to the connected shaft. The core resists water, petroleum-based chemicals, and inorganic acids while also insulating bearings, encoders, and other shaft components from stray electric current. Clamping screws provide hold without marring shafts; they’re useful in applications where shafts are frequently assembled and disassembled.
