INA Bearing configuration includes not only the bearings, but also with bearing parts, such as shaft and bearing. The lubricant is also bearing configuration is a very important part of the lubricant to prevent wear anti-corrosion, so that the bearing in order to fully play its role. In addition, the seals is a very important part, the sealing performance of the lubricant clean is essential. Kept clean and have a profound impact on the life of the bearing, which is why lubricants and seals has become part of the SKF bearing service reason.

(1) bearing a share of the machinery space and location
In mechanical design, generally determine the size of the shaft, then select rolling bearings, according to the size of the shaft. Is usually small axis of the choice of ball bearings, shaft optional roller bearings. However, INA bearings in the machine direction of the diameter of the restricted choice of needle roller bearings, light weight and ultra-light series ball or roller bearings; when the bearings in the axial position of the machine is limited, the choice of narrow or narrow special series of ball or roller bearings.

(2) bearing load suffered by size, direction and nature of
The load is the most important factor in the selection of bearings. Roller bearing to withstand heavier loads and ball bearings to withstand a lighter or medium load, carburizing steel or bainite hardening of the bearing can withstand shock and vibration loads. Subject to pure radial loads in the load direction of action, may make use of deep groove ball bearings, cylindrical roller bearings or needle bearings. Withstand the smaller pure axial load, thrust ball bearings can be used; withstand a larger pure axial load, the choice of thrust roller bearings. INA Bearing radial and axial load is generally used in the angular contact ball bearings or tapered roller bearings. Cantilever support structure, often with tapered roller bearings or angular contact ball bearings, and in pairs.

(3) bearing aligning performance
When the centerline of the shaft and the bearing centerline, angle error, or due to the shaft two bearing spacing of the large axis of rigidity in smaller, vulnerable force bent or tilted, the choice of the tune with a good aligning properties of aligning ball or spherical roller bearings, as well as outside the ball bearings. Such INA bearing axis is slightly inclined or curved, to maintain normal work.

(4) bearing rigid
Bearing rigidity, the bearing generating unit deformation force required size. The rolling bearing elastic deformation is very small, most machines do not have to consider, but in some machinery, such as machine tool spindle bearing stiffness is an important factor, the general should be used in cylindrical and tapered roller bearings. Because these two types of bearing the load bearing, the rolling element and raceway is point contact, less rigid. In addition, various types of bearings can preload, to increase the support rigidity of purpose. Such as angular contact ball bearings and tapered roller bearings increase bearing rigidity to prevent vibration of the shaft, often in advance of installation to exert a certain degree of axial force, mutual compression. Highlighted here: Preload is not too large. Too large will allow INA bearing friction increases, the temperature rise increased, affecting bearing life.

In the chapter after the introduction of integrated technology, design of bearing arrangement will see the essential information provided in accordance with the general requirements of the order. Obviously, it is not possible all the information needed by every conceivable bearing application are included. For this reason, we will in many places mentioned in the INA applications engineering services, the services include the right choice for technical support bearings and bearing configuration calculation. Bearing configuration of the technical requirements of the higher, the experience of bearing used in a specific application is more limited, the more you should take advantage of this service.

Information is usually included in the comprehensive chapter applies to the common rolling bearing, or at least for a set of bearings. If you only need the exact information of certain INA bearing, can be found in the text before the corresponding section of the classification table.
