High-Load Plastic Ball Bearings
With two rows of balls, these lightweight bearings have greater durability and load capacity—and a wider profile—than single-row plastic bearings. They’re commonly used in bottle-filling machines and other food-processing applications. The acetal body doesn’t absorb water, so it can operate in liquids or be washed down without losing strength. The balls are made of either glass or 316 stainless steel—both materials are corrosion resistant. Since there’s no metal-on-metal contact between the balls and the body, these bearings don’t require lubrication.

Thrust Ball Bearings
Steel balls and washers allow these bearings to handle higher loads than bearings with stainless steel components. With an open design, they dissipate heat more efficiently than one-piece thrust ball bearings.
Bearings with steel cage and with bronze cage handle higher loads and speeds than bearings with a plastic cage.

Linear and Rotary Ball Bearings
Engineered for simultaneous linear and rotary motion, these bearings are used with round end-supported shafts. The fixed-alignment design is for use where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).
Bearings with end seals are designed to keep lubricant in and dirt out.
Bearings without a maximum stroke length are only limited by the length of shaft they're used on.

High-Load Threaded Track Rollers
With a double row of cylindrical roller bearings, these rollers provide the highest combination of speed and dynamic radial load ratings of any threaded track roller we offer. Also known as cam followers, track rollers support loads while guiding and positioning work. Thread the stud directly into a component or secure with a nut for through-hole mounting. All rollers are permanently lubricated.
Crowned rollers have a slight curve, invisible to the naked eye, which helps them stay centered on surfaces that are slightly misaligned or not perfectly flat.
Rollers with seal have an end seal to protect the rolling elements from dirt and contamination.

Shaft-Mount Track Rollers
Also known as yoke-style cam followers, these rollers have more mounting flexibility than threaded track rollers. They're typically mounted onto a shaft or clevis rod end. Lubricate rollers through a hole and groove in the inner ring.
Crowned rollers have a slight curve, which is invisible to the naked eye, to stay centered on surfaces that are not perfectly aligned and/or not perfectly flat.
Rollers with seal have end seals to protect rolling elements from dirt and contamination.
