| Plain Bearing | Bushings / sleeve bearings, also called journal or plain bearings, are used to constrain, guide, or reduce friction in rotary or linear applications. They work by means of sliding action as opposed to the rolling action used by ball, roller and needle bearings. As in all bearings, proper lubrication is required to reduce wear and friction. Terms such as fluid film, self-lubricated, hydrostatic, and hydrodynamic are commonly designations for plain bearings. | ||

| Bore | The bearing industry uses a standard numbering system for bearings with metric-diameter bores. If the bore is hexagonal, enter the dimension across the flats. If the bore is tapered, enter the smaller diameter. For bore sizes 04 and up, multiply the bore size by 5 to identify the bore diameter in millimeters (mm). Refer to the table below. | ||||||||||||||||||||||||||||||||||||||||||||||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||||||||||||||||||||||||||||||||||||||||||||||
| |||||||||||||||||||||||||||||||||||||||||||||||
| Outside Diameter | Enter the outside diameter of the bearing. For housed bearings, include the housing. For flanged bearings, exclude the flange. | ||||||||||||||||||||||||||||||||||||||||||||||

| Application | |||
| Your choices are... | |||
| Airframe / Aircraft Control | Aircraft Control and Airframe Bearings are specially designed to meet the demands of aircraft control and aerospace applications. They can be of ball, roller, or needle roller construction. Most aircraft control and airframe bearings are manufactured to U.S. government military (MIL-SPEC) standards. | ||
| Aerospace | Bearings designed for aerospace applications such as jet engines and helicopters. | ||
| Agriculture | Bearings designed for agriculture equipment and environments. | ||
| Automotive | Bearings specially designed for the automotive industry. | ||
| Ball Screw Support | These bearings are specially designed for use in ball screw or lead screw applications. Most ball screw support bearings are angular contact bearings with a steep contact angle, such as 60°, and are available in duplex, triplex and quadruplex configurations. Other designs include bearings containing separate thrust and radial roller bearings in a single assembly. Cartridge designs are also available that include a housing, seals, and bearings. | ||
| Instrument / Miniature | Instrument and miniature bearings are small deep groove or angular contact bearings. They are used in applications requiring very small bearings, such as dental drills and computer disk drives. | ||
| Medical /Dental | Bearings specially designed for medical or dental equipment. | ||
| Military | Bearing manufactured in accordance with the U.S. Government standards as dictated by the appropriate military specifications. | ||
| Pump | These bearings are designed for the conditions found in pumps, including high loads, poor or degraded lubrication, and high operating temperatures. | ||
| Spindle / Super Precision | These are high precision bearings intended for use in machine tool spindles. | ||
| Sporting and Consumer Goods | Bearings specially designed for the sporting and consumer goods market. Products in the sector include inline skates, skateboards, and fishing reels. | ||
| Other | Other, unlisted application. | ||

|
| ||
| Features | |||
| Your choices are... | |||
| Flanged | The bearing has a flange for mounting or locating. | ||
| Self-aligning | Bearing outer ring is spherically shaped and matched to the bore of a housing, allowing for some misalignment. | ||
| Snap Ring / Snap Ring Groove | Used to provide a locating shoulder when mounting bearing. | ||
| Split Bearing | Bearing and housing are completely split to the shaft for easy bearing replacement and inspection. | ||
| Spherical Outside Diameter | The bearing is tolerant of misalignment and has a greater load capacity than internal self-alignment, but requires more radial space. | ||
| Thin-section | Thin-section bearings have small cross-sections with respect to their diameter. They are designed to save space, lower the weight of a design, and reduce friction. Some thin-section bearings are also referred to as torque tube bearings. | ||
