1. Radial Load—Radial loads refer to forces that are applied perpendicular to the shaft and act along the radial line drawn from the center of the bearing.
2. Thrust Load—Thrust loads refer to forces that are applied parallel to the shaft and act along the radial line drawn from the center of the bearing.
3. Cage—The cage is the part of the bearing which separates and spaces the rolling elements. The cage is often made of a molded or stamped outer casing or coating of metal or fabric, but may also be made of plastic or other materials.
4. Roller—Rollers are the rolling elements of the bearing, and are typically cylindrical in shape.
5. Raceway—The raceways are the tracks upon which the rolling elements of the bearing travel. The raceway is typically grooved or scored to allow for greater durability and increased contact and load bearing capacity.
6. Seal—The seals are generally made of rubber or synthetic materials, and help to keep the interior of the bearing clean and reduce the amount of contaminants and foreign material that could cause damage or problems with the bearing.
7. Retainer—The retainer is the part of the bearing that holds all of the components of the bearing together. The retainer is generally made of a lightweight, durable material such as aluminum or plastic.
8. Seals—Seals are an important component of the bearing, and help to keep the interior of the bearing free from contaminants and other foreign materials. There are several types of seals, including a grease seal, wire seal and dust cap.
9. Grease—Grease is an essential component of a bearing, and helps to reduce wear and friction between the rolling elements. Grease also helps to protect the bearing from contaminants and other substances.
10. Shield—Shields are generally made of metal, and are designed to protect the rolling elements of the bearing from dust and other contaminants.
11. Bearing Frequency—The frequency of a bearing is the number of revolutions per minute (RPM) of the bearing shaft.
12. Bearing Temperature—The temperature of a bearing is the average temperature of the bearing over a given amount of time.
13. Operating Speed—The operating speed of the bearing is the speed at which the bearing is expected to operate.
14. Preload—Preloads are applied to bearings to help ensure that the rolling elements remain in contact with the raceway.
15. Bearing Life—The life of a bearing is the amount of time that the bearing will operate before it requires replacement.
16. Clearance—Clearance is the amount of space between the surfaces of the bearing and its components, such as the raceway and rolling elements.
17. Radial Wall—The radial wall is the inner surface of the bearing that is farthest from the center of the bearing.
18. Axial Wall—The axial wall is the outer surface of the bearing that is closest to the center of the bearing.
19. Vibration—Vibration is the oscillation of a bearing caused by the rotation and motion of its components, such as the rings, cages, and rolling elements.
20. Bearing Fit—The fit of a bearing is the amount of tightness between the components and the outside of the bearing.
