Startup friction causes these bearings to release a thin layer of oil on the bearing’s surface. They’re flanged, so they handle loads both parallel and perpendicular to the shaft. They’re also known as Oilite® bearings.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds. Startup friction causes these bearings to release a thin layer of oil onto their surface. Color is silver because of the iron.

863 iron-copper bearings are also known as Super Oilite® bearings.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

With oil for reduced friction and iron for added strength, these bearings handle frequent stops and starts in high-load applications. They withstand greater weight and shock loads than standard bearings, but operate at lower speeds.

These bronze bearings are strong, wear resistant, and excellent at handling shock loads. They’re sometimes called 660 leaded bronze bearings.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

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 spiders provide good vibration damping and chemical resistance. Hytrel spiders provide fair vibration damping and excellent chemical resistance. Polyurethane spiders and split spiders provide fair vibration damping and good chemical resistance.

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. Spiders with medium-soft hardness are the most commonly used and are good for applications that start, stop, and reverse often. Those with medium hardness handle higher torque than those with medium-soft hardness, but they don’t reduce vibration as well.

Split spider covers hold the spider in place.

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 nitrile rubber 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.
