About Ball and Roller Bearings

Ball Bearings

Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Permanently Lubricated Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.

Sealed bearings have even better resistance to dust and contaminants than open bearings.

Ultra-Thin Ball Bearings

Shielded

These bearings have twice as many contact points as angular-contact ball bearings. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.

Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

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.

Multipurpose Sleeve Bearings

These 660 leaded bronze bearings are strong, wear resistant, and excellent at handling shock loads. They’re sometimes called 932 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.

Spherical-Roller Bearings

Two rows of rollers give these bearings dynamic radial load capacities over five times higher than comparably sized tapered-roller bearings. Also known as rock crusher bearings, they handle heavy shock loads and are used for metal milling machinery, mining and oil field equipment, and in paper mills.

Needle-Roller Thrust Bearings

Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings. Because of the large contact area between the rollers and washers (not included), these bearings are great for medium to heavy duty, low-friction jobs. For use on hardened and ground surfaces.

Mounted Ball Bearings

Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.

Bearings with a set screw secure to shafts without using a collar. They let shafts rotate in both directions, so they’re good for applications where you need to reverse. However, the set screw will leave some marring on the shaft.

Insert Bearings

Swap out worn inserts instead of replacing the entire mounted unit. Use the manufacturer model number on your existing mounted bearing to choose a compatible insert. Inserts must be used with the manufacturer model number specified.

Quick-Disconnect (QD) Bushings

Clamp On

The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
