The Proper Fit of a Thin-Section Ball Bearing
The proper fit between the shaft and housing of a thin-section ball bearing is vital for the proper operation of the bearing. The shaft and housing should be round enough to minimize the internal clearance of the bearing. Applications with a rotating inner ring should use a light press fit. Refer to Tolerance Tables to determine the best fit. Once this is determined, the thin-section ball bearing can be ordered. There are a number of factors to consider when determining the right fit for your application.
In the aerospace industry, thin-section ball bearings have many uses. For example, they are often used in the drive of radar antennas. They are also often used for airborne turret azimuth assembly. They also have excellent multi-load capacity and low torque. In addition, they are highly resistant to corrosion and are designed for vacuum operations. These characteristics make them ideal for a range of applications. And because they are so lightweight, they can be installed on a wide variety of aircraft.
A thin-section ball bearing has four points of contact. A 4-point contact provides high stiffness and minimal deflection. This makes them ideal for situations where space is an issue. Furthermore, a 4-point contact thin-section ball bearing has multiple load carrying capabilities and is extremely stiff. These properties make these bearings ideal for applications with tight space constraints.

Several types of thin-section ball bearings have different rated load capacities. The most common of these are the shield-type and the wide-inner-ring products. They are tightened to the shaft using two mounting balls at two locations. Both methods use an adapter to mount on the shaft. A third type of thin-section ball bearing is a deep groove type bearing where interference between the inner ring and shaft causes the balls to move independently.
A few features of RBC Thin Section Ball Bearings make them suitable for a variety of applications. One feature is that they are lubricated with oil. The unsealed versions are coated with MIL-L-3150 oil and drained after use. The sealed versions use MIL-G-23827 grease. The extra lubricant can be purchased if the application requires it. However, lubrication is the most common cause of bearing failure.
When selecting a RBC Thin Section Ball Bearing, consider the loading condition and application. For example, a duplex pair of angular contact ball bearings may be used for combined, moment, and heavy thrust loads. You may also choose to mount two X-Type bearings on the same shaft, which will reduce the overall weight and space requirements. The RBC group also provides custom bearings with unique features, including radial play, preloading, and other features.
