What is a Ball Bearing Ring?

You may have heard of Angular Contact Ball Bearings and Single-row deep groove ball bearings, but what is a Ball Bearing Ring? Let us learn more about these two types of bearings and the benefits that they bring to your life. You may also be interested in Hybrid and Ceramic Hybrid bearings. These are all excellent choices for your automotive, boat, or industrial applications. Whether you are replacing your old, worn-out bearing or searching for a new one, these articles will help you choose the right bearing for your needs.

The design units for angular contact ball bearings are bore, outside diameter, and outer ring width. These dimensions can be specified in inches, millimeters, and metric units, and some manufacturers may specify parts in one or both of these measurements. For metric diameter bores, the bearing industry follows a standard number system: multiply the bore's measurement by five to get millimeters. The resulting number of millimeters should be used as a guide for choosing angular contact ball bearings.

Single-row deep groove ball bearings have several advantages. They are economical and versatile, making them popular amongst manufacturers of industrial equipment. They are also easy to maintain, making them one of the most widely used types of rolling bearings today. Schaeffler is one company that manufactures a wide variety of single-row deep groove ball bearings, including generation C bearings, which have features designed to minimize noise.

Ceramic hybrid bearings consist of steel rings and ceramic balls. Ceramic is much stiffer and stronger than steel, causing increased stresses in the rings, but the resulting load capacity is lower. Ceramic balls also resist electrical arcing, making them useful in environments without lubrication. Additionally, ceramics do not degrade due to oxidation, ensuring optimum performance in even the most hostile environments. Ceramic bearings are highly durable and are widely used for various industrial applications.

Hybrid bearings in ball bearing rings are different from standard ball bearings because they use two metals in place of one. The metals used are silicon nitride and steel. Zirconium is bone colored, while Silicon Nitride is white. Both are hard but have slightly different properties. The main difference between them is their ability to maintain their properties over a wider temperature range and greater load.

Unlike other metals, the 300 series stainless steel offers superior corrosion resistance. It is non-magnetic and low in carbon content. It is only suitable for low-speed and low-load operations. To avoid corrosion, bearing surfaces undergo a passivation process. This process involves a film of passive corrosion protection to reduce the risk of rust spots. Sometimes, bearing shields are made from AISI303 or AISI304 stainless steel, which have a moderate corrosion resistance but are more easily shaped.

Generally, Conrad-style ball bearings exhibit contact ellipse truncation under axial loads. This occurs when the outer ring ID is greater than the inner OD. Proper lubrication is crucial to avoid truncation. A wide range of lubricants are available, but the most appropriate type should be identified by labeling. The truncation is caused by excessive load, axial load, or shock.
