Miniature bearings and instrument bearings carry moderate radial and thrust loads at low operating torque while providing high performance in a small envelope design. These types of bearings are single row ball bearings available in up to 1 1/8" outer diameter (OD) sizes

Ball Bearings

(687 companies)
Ball bearings are used to provide smooth, low friction motion in rotary applications. Ball bearings types include radial ball bearings (deep groove and angular contact) and thrust ball bearings.

Plain bearings and sleeve bearings (also referred to as bushings or journal bearings) are used to constrain, guide or reduce friction in rotary or linear applications. They function via a sliding action.

Angular Contact Bearings

(324 companies)
Angular contact bearings are designed so that a contact angle between the races and the balls is formed when the bearing is in use.

Roller Bearings

(544 companies)
Roller bearings are used in rotary applications to replace sliding movement with low friction, rolling motion. The principal types of roller bearings are cylindrical, spherical, and tapered.

Thrust Bearings

(361 companies)
Thrust bearings are comprised of components which support axial loads, and little to no radial loads. Types include tapered, cylindrical, spherical, and needle roller thrust bearings, thrust ball bearings, fluid-film thrust bearings, and magnetic thrust bearings.

Plastic Bearings

(159 companies)
Plastic bearings are used in wet and corrosive environments, clean environments, areas that are difficult to lubricate, and applications that require non-magnetic bearings.

Ceramic Bearings

(101 companies)
Ceramic hybrid bearings, the most common type of ceramic bearing, are constructed of steel inner and outer rings with ceramic (typically Si3N4) balls in place of steel. Common types of ceramic bearings are angular contact and conrad.

Linear Bearings

(334 companies)
Linear bearings are used in applications where a component needs to be moved along a straight line with high accuracy.

Air Bearings

(33 companies)
Air bearings use a thin film of pressurized air to support a load. They do not generate friction.

Pillow Block Bearings

(353 companies)
Pillow block bearings are mounted bearings that are used to provide load support for a rotating shaft 's axis.

Needle Roller Bearings

(286 companies)
Needle roller bearings are a type of radial roller bearing with rollers whose length are at least four times their diameter. These bearings are valued for their high load capacity and low sectional height.

Spherical Plain Bearings

(204 companies)
Spherical plain bearings accommodate wide-ranging angular misalignment with a ball-and-socket type design. They are frequently used in linkages and control rod applications.

Radial Ball Bearings

(373 companies)
Radial ball bearings are friction reduction, rotation devices that carry loads radially around its axis. A subtype of ball bearings, they operate through the use of lubricated steel balls placed between two circular guides. They are frequently called deep-groove bearings.
