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

Ceramic balls are rolling, spherical elements that are used in check and ball valves, bearings, and other mechanical devices that provide rotary or linear motion. They can provide higher stiffness, lower thermal expansion, lighter weight, increased corrosion resistance, and higher electrical resistance than comparable steel products

Thin-section bearings have small cross-sections with respect to their diameter

Super precision and spindle bearings are high-precision bearings that are designed for use in machine-tool spindles and other precision applications. Most super precision bearings and spindle bearings carry a high quality-rating such as ABEC-7 or ABEC-9, and run coolly and smoothly at high speeds

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

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

Radial or deep groove bearings can handle radial and axial loads to varying degrees, but are typically used when the primary load is in the radial direction

Control and airframe aircraft bearings are designed to meet the rigorous demands of aircraft control and aerospace applications

Ceramic tube and ceramic rod products are suitable for use in applications requiring high temperature strength, erosion resistance, electrical or thermal insulation, and other specialized characteristics

Industrial ceramic materials are non-metallic, inorganic compounds that include oxides, carbides, or nitrides. They have high melting points, low wear resistance, and a wide range of electrical properties

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

Tapered roller bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers, which are profiled to distribute the load evenly across the roller

Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but crowned or end-relieved to reduce stress concentrations

Needle roller bearings are designed for radial load applications where a low profile is desired

Dielectric ceramics and substrates are electrical insulators with dielectric strength, dielectric constant and loss tangent values tailored for specific device applications
