What Is a Deep Groove Bearing?
A Deep Groove Bearing is a cylindrical ball bearing that has a single point of contact with the raceways.
This contact occurs through the radial plane, thereby preventing a radial load from grazing stationary parts. Deep groove ball bearings have two main series: the series 60 and 618. Series 60 bearings have larger cross-sections, and can support the same load as series 618 and 619 bearings.
There are several types of Deep Groove Bearings, each with its unique characteristics. Low friction, sealed deep groove bearings use synthetic rubber to reduce friction and are a good choice for applications in which high temperatures are a concern. Non-contact seals are also suitable for high speeds, but must be lubricated properly for safety reasons. Seals can be installed at any position on the bearing, as long as they do not contact the bearing surfaces.
The inner ring of a Deep Groove Bearing is deeper than that of other types. There is only one shoulder in the outer ring, making it easy to mount and maintain. Because of their precision, deep groove bearings are often used in gyroscopes. Deep groove bearings also offer a lower cost, longer service life, and low maintenance. These features make Deep Groove Ball Bearings a superior choice for many applications.
Double-row Deep Groove Bearings are suitable for bearing arrangements where a single row ball bearing is not sufficient. They have more rolling elements and a greater load capacity than a single row bearing. Double-row Deep Groove Ball Bearings have cages made of either polyamide or pressed steel, although pressed steel cages are the most common. They can also be made of rubber or steel. Some Deep Groove Ball Bearings are available as shielded and open.
These bearings are also known as spiral groove or rifle bearings. The special groove patterns of the spiral groove enable these bearings to reduce friction and wear without lubricants. The resulting pressure is equivalent to the force exerted on the bearing. The pressure is sufficient for the bearing to support the load. In addition to their superior load capacity, they also feature superior resistance to cavitation. Its design is highly versatile and can be used in various applications.
A rigid bearing arrangement requires matching of both the inner and outer rings. This arrangement is advantageous over single or unmatched bearings. In a matched bearing, the inner and outer rings lock together. Life time calculations must take into account the preload as an extra axial load. DUV matched bearings with preload require a preload of 2% of their dynamic load rating. They can be designed with different preloads to match your specific requirements.
When selecting a Deep Groove Bearing, there are several factors to consider. First of all, the load capacity must be considered, as the higher load capability results in a slower speed. Once the selection is made, it is important to verify the calculated life of the bearing. This way, the bearing will last for a long time.
