Ball Bearings

Smoother than smooth—the balls inside these bearings roll nearly friction-free. You’ll often find them on rapidly rotating parts, from the whirring chuck on a power drill to the spinning shaft on an electric motor.

Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.

Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

Corrosion-Resistant 440C Stainless Steel—Combine the strength of steel with the corrosion resistance of stainless steel. These bearings won't degrade from water or mild chemicals, such as the ammonia in cleaning solutions. However, they'll weaken when exposed to salt water and harsh chemicals, such as bleach.

ABEC Rating—Bearings with an ABEC rating meet industry tolerance standards established by the Annular Bearing Engineers Committee (ABEC). They're rated on a scale from 1 to 9. The higher the rating, the tighter the tolerance. Bearings rated ABEC 1 or 3 are precise enough for most applications. If your application consistently runs at high speeds or requires high accuracy, consider bearings rated ABEC 5 or higher, since they generate less friction and heat.

Four-Point Angular Contact Ball Bearings

Support complex movement in multiple directions with a single compact bearing. The balls distribute weight at four points, so these bearings handle radial, thrust, and moment loads all at once. For example, you’ll often find them in robot arms, which rotate, extend, and twist while supporting an object’s weight. Thinner than two standard angular contact ball bearings paired together, these bearings squeeze into tight spaces. They’re commonly paired with large hollow shafts to run electrical wire and other lines.

Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

Light Duty Mounted Ball Bearings with Two-Bolt Flange

With a two-piece housing made from thin pressed metal, these bearings are a cost-effective option when extreme precision isn't necessary. Less stable than bearings with forged, one-piece housings, they're good for hand-cranked systems, gravity feed conveyor rollers, and other low-speed applications. The balls inside roll nearly friction-free to support smooth shaft rotation. The housing mounts in place with a two-bolt flange, the most common type of flanged bearing.

Lubricate regularly to keep your bearing in tip-top shape. These bearings come packed with grease and sealed to block out dust and contaminants.

Steel Housing—Best for dry environments as moisture will cause them to rust.

304 Stainless Steel Housing—Prevent rust from exposure to moisture and mild chemicals, including ammonia-based cleaning solutions.

Set Screw—Turn the screw to lock your shaft in place. A simple, reliable choice, set screws grip tightly, but they can mar shaft surfaces.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.

Flanged Ball Bearings

Install these bearings inside a housing and they won't budge. The flange presses against the housing wall, so vibration and other sudden forces parallel to the shaft (thrust loads) won't knock them off-kilter.

Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.

Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

Mounted Ball Bearings

Smoother than smooth—the balls inside these bearings roll nearly friction-free. The sturdy housing bolts down to support shafts as they turn.

Lubricate regularly to keep your bearing in tip-top shape. Bearings with seals and shields keep lubricants in and contaminants out, and come packed with grease. Open bearings require initial lubrication and offer less protection against dust and debris.

Aluminum Housing—One-third the weight of cast iron but not as strong. Aluminum also resists corrosion.

Press Fit—For a tight connection to the shaft, install with a press or by heating and then cooling the bearing. Also known as an interference fit.

Panel-Mount Ball Bearings

Smoother than smooth—the balls inside roll nearly friction-free to support smooth rotation. They mount securely in thin panels.

All bearings come lubricated. Plan to relubricate regularly to keep them in tip-top shape. Seals and shields hold lubricant in while keeping dust and contaminants out. Open bearings require more frequent relubrication.

Steel Housing—Best for dry environments as moisture will cause them to rust.

Clinch Panel Mount—Secure these self-clinching bearings into sheet metal panels for a permanent hold. Install them using an air-powered or hydraulic press—no need for precision-bored holes or machined mounts. They're not for use in plastic panels.

Press Fit—For a tight connection to the shaft, install with a press or by heating and then cooling the bearing. Also known as an interference fit.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.

Light Duty Mounted Ball Bearings

With a two-piece housing made from thin pressed metal, these bearings are a cost-effective option when extreme precision isn't necessary. Less stable than bearings with forged, one-piece housings, they're good for hand-cranked systems, gravity feed conveyor rollers, and other low-speed applications. Inside, the balls roll nearly friction-free to support smooth rotation.

Lubricate regularly to keep your bearing in tip-top shape. These bearings come packed with grease and sealed to block out dust and contaminants.

Steel Housing—Best for dry environments as moisture will cause them to rust.

304 Stainless Steel Housing—Prevent rust from exposure to moisture and mild chemicals, including ammonia-based cleaning solutions.

Set Screw—Turn the screw to lock your shaft in place. A simple, reliable choice, set screws grip tightly, but they can mar shaft surfaces.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.
