How High Precision Ball Bearing Are Used in Applications Requiring Precision Dimensions and Rotational Tolerances

High Precision Ball Bearing are used in applications requiring precise dimensional and rotational tolerances, such as machine tools and aerospace equipment. To achieve the required tolerances, engineers must ensure that the manufacturing process and design meet certain requirements. For example, it is critical to ensure that the inner and outer raceway diameters match up exactly. In addition, the choice of material is also important because different materials have varying temperature limits. High-precision ball bearings need to be able to operate at very high temperatures, but if the material is not appropriate for the operating temperature, it will quickly wear down and cause premature failure.

One of the most common causes of high-precision bearing malfunction is improper handling. While high-quality bearings are usually demagnetized prior to shipment, induced magnetism can occur during transport and assembly. This can attract particles that can lead to contamination. It is therefore essential to carefully handle the bearings until they are ready for use and to always wear gloves when working with them. Another common problem is corrosion. This can happen through corrosive gases or simply through contact with moisture, which can result in pitting and wearing of the inner and outer raceways.

The rotational accuracy of a bearing is the result of the coupling effect between the rolling elements and the internal geometric error of the component parts. The rotational accuracy of a high-precision ball bearing is significantly affected by the roundness error of the inner and outer races and rollers. However, the rotational accuracy of a high-precision bearing is also influenced by the angular misalignment between the shaft and housing shoulders.

In order to analyze the impact of the angular misalignment on the force and temperature characteristics of an angular contact ball bearing, we studied the dynamic behavior of a high-precision angular contact ball bearing with an outer ring tilt angle of 0.02 degrees. The result showed that the local heat generation tendency in the direction perpendicular to the radial force increased with the increase of the tilt angle. However, the variation tendency of the contact angles was relatively unchanged.

The key to selecting the right grease for your application is to know how fast the bearing will be running, which is called the application rpm (ndm). To find the application rpm, multiply your application speed by the diameter of the center of the balls in the bearing (dm). Then, compare this value with the max speed indicated on the grease data sheet. If your ndm is higher than the grease maximum speed, you may need to consider using a different lubricant. Choosing the right lubricant can help ensure that your high-precision bearings run smoothly and safely for long-lasting performance.
