Quick-Mount Ball Bearings

Slip onto a shaft and secure with the turn of a screw. You don't need any special tools to mount these bearings.

Set-Screw Shaft Mount—Tighten the screws against the shaft to hold the bearing in place. For high-speed applications, consider clamp-on shaft mounts, which are less likely to slip.

Clamp-On Shaft Mount—The clamp tightens around the shaft for a strong 360° grip. These mounts attach more securely than set screws to reduce vibration. Plus, there aren't any screws pressing into the shaft, so it stays free from damage. Also known as a concentric lock.

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

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

Sealed—The best choice for dirty environments. A barrier seals out dust so it won't gunk up or wear down the balls. However, these bearings retain the most heat since air can't flow through.

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.

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.

Sealed—The best choice for dirty environments. A barrier seals out dust so it won't gunk up or wear down the balls. However, these bearings retain the most heat since air can't flow through.

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.

Extended Inner Ring—Connect to mating parts without the need for a spacer. The inner ring juts out farther than the outer ring, so shaft collars and other objects won't touch the bearing's moving parts.

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.

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

Sealed—The best choice for dirty environments. A barrier seals out dust so it won't gunk up or wear down the balls. However, these bearings retain the most heat since air can't flow through.

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

Quick-Mount Ball Bearings for Food and Beverage

You don't need any special tools to install these bearings in food production areas. Slip them onto a shaft and secure with the turn of a screw for easy mounting. Greased with NSF-registered H1 lubricant, these bearings are safe to install on food-processing equipment, such as conveyor belts, so long as they don’t directly touch the food. They're IP69K rated, so they'll stand up to the hot water from a pressure washer when cleaning your facility at the end of the day.

Set-Screw Shaft Mount—Tighten the screws against the shaft to hold the bearing in place. For high-speed applications, consider clamp-on shaft mounts, which are less likely to slip.

Corrosion-Resistant Nickel-Plated Steel—These bearings resist mild chemicals, such as the ammonia in cleaning solutions, while maintaining the strength of steel. The nickel coating can wear or chip over time, though. If it does, the steel beneath will rust quickly.

Sealed—The best choice for dirty environments. A barrier seals out dust so it won't gunk up or wear down the balls. However, these bearings retain the most heat since air can't flow through.

Ball Bearings with Retaining Ring

Sealed

No need for complicated tools—install these bearings by hand inside a housing. The ring stops the bearing from being jostled out of place when it experiences sudden forces parallel to the shaft (thrust loads).

Sealed—The best choice for dirty environments. A barrier seals out dust so it won't gunk up or wear down the balls. However, these bearings retain the most heat since air can't flow through.

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