This type of ball bearing it often the most popular because of its versatility. They are suitable for high speeds and can handle an excellent radial load capacity, all will hardly any maintenance required.
“Deep Groove” refers to the race (the groove where the balls rest). There is as a result a larger space between the inner and outer bands, than the diameter of the ball. This leaves space for the rubber seals.
The purpose of a ball bearing is to determine the relative position of two parts (usually the shaft and the bearing casing) and also to ensure their free rotation while transmitting the load between them. At substantial rotational speeds (for instance in gyro ball bearings), this application can be extended to include free rotation without almost don in the bearings. To achieve this, the two elements of the bearing could be separated by a layer of adhesive liquid film called an elastic hydrodynamic lubricating film. remarked that flexibility can be maintained not merely when the bearing bears the load on the shaft, but also when the bearing is preloaded to ensure that the positioning precision and steadiness of the shaft does not go beyond 1 microin or 1 nanoin. Hydrodynamic lubricating film.
Deep groove ball bearings mainly have radial load, but can also support radial and axial load. When the only radial loads, the contact angle is zero.
When the deep groove ball bearings with a larger radial clearance, with angular speak to bearings can bear significant axial load, deep groove ball bearing friction coefficient is tiny, the speed limit is also high.

Single row deep groove ball bearings are manufactured as start type (unsealed), sealed and shielded, the most used sizes of deep groove ball bearings happen to be also stated in sealed versions with shields or contact seals on one or both sides, the bearings with shields or seals about both sides are lubricated forever and are maintenance free. A sealed bearings seals features speak to on the bearings inner and external, a shielded bearings shield has got speak to on the outer only, and Shielded bearings are primarily meant for applications where the inner ring rotates. If the external ring rotates, there exists a risk that the grease will leak from the bearing at great speeds.
Double-row Deep Groove Ball Bearing have deep uninterrupted raceways and high conformity between the balls and raceways.
They are able to carry axial loads performing in both directions in addition to radial loads.Twice row deep groove ball bearings are
very suited to bearing arrangements where the load carrying capability of an individual row bearing is inadequate. For the same
external and bore diameters, twice row bearings are somewhat wider than solitary row bearings but have considerably higher load
carrying capacity than single row bearings in the 62 and 63 series.
EPT deep groove ball bearings for extreme temperatures correspond in design to standard single row deep groove ball bearings of the same size. They haven’t any filling slots and can accommodate usual axial loads in addition to radial loads. The radial interior clearance is a multiple of C5 to prevent the bearings from seizing, even when they cool rapidly. All areas of the bearing and shields are manganese phosphated to improve adhesion of the lubricant to the metallic and provide additional security against corrosion.
