Hex-Bore Ball Bearings

No need for set screws—the inside corners of these bearings hold them in place on hex shafts as they rotate. They're a good choice when your setup needs to come apart frequently, since there aren't extra mounting steps.

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.

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.

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.

Conveyor Roller Ball Bearings

Replace worn bearings or press-fit these into tubing or pipe to create a roller. The polypropylene housing resists moisture and chemicals, so these bearings hold up in washdown environments. Stainless steel balls provide corrosion resistance for long service life in wet or humid conditions.

Hex Flanged Eccentric Bushings

Often used with V-groove wheels or track roller carriages, these off-center bushings create precise mounting clearance. As you turn the bushing’s hex flange with a wrench, it adjusts the distance between the V-groove wheel or carriage and the rail. Tighten the axle bolt in place once you’ve adjusted them. Made of 303 stainless steel, these bushings have very good corrosion resistance.
