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.

Set Screw Collar Ball Bearings

With Retaining Ring

Slip these bearings onto a shaft and secure with the included set screws, no special tools required. All have an extended inner ring for additional shaft support.

Bearings with a black-oxide steel ring have some corrosion resistance.

Sealed bearings block out dust and other contaminants better than shielded bearings.

Bearings with a retaining ring have a removable retaining ring that holds the bearing inside a housing.

Ultra-Thin Ball Bearings

Open

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.

Open bearings dissipate heat more efficiently than shielded bearings.

Precision Angular-Contact Thrust Ball Bearings

These bearings have angular raceways for combined thrust and radial loads—install them where precision tolerances are required for accuracy and high speeds. They’re often used in spindle applications. To handle thrust loads in both directions, they have a double-row construction. Pair them with cylindrical roller bearings to better handle radial loads. They have an open construction to dissipate heat efficiently.

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.

Chemical-Resistant Dry-Running Sleeve Bearings

Fiberglass-Backed PTFE Plastic

These bearings stand up to a wider range of chemicals than other dry-running sleeve bearings.

Fiberglass-backed PTFE are strong and vibration resistant. A layer of PTFE on the ID of the bearing reduces friction.

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.

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.

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

Set screw bearings secure to shafts as you tighten their screw. They don’t need a collar, but the screw leaves some marring on shafts. Use them in applications where shafts rotate in both directions.

Frictionless-Motion Mounted Linear Air Bearings

Bearing in Housing

Float bearings on air for precise, frictionless movement. Unlike traditional bearings that can wear your shaft down, these bearings are suspended using pressurized air for linear and rotary motion. Since there’s no friction, they glide smoothly and silently without wearing over time. These are self-aligning bearings, so they compensate for some shaft misalignment. They must be connected to a compressed air system.
