The deep groove ball bearing is mainly used to be subject to radial load, but it can also be subject to given axial load. When the bearing radial windage is increased, the deep groove ball bearing is provided with characteristics of radial-thrust bearing, and can be subject to larger axial load. These bearings can limit axial moving to two directions. The inner race and the outer race are allowed to relatively incline 8¡¯ to 16¡¯ according to the size of the windage.

Deep groove ball bearing comprises four basic components, they are respectively an inner raceway (inner race), an outer raceway (outer race), steel balls and a holder. Under normal operating conditions, the inner raceway, the outer raceway and the steel balls are subject to load, and the holder plays a role of separating and keeping the steel balls stable.

 
 
Deep groove ball bearings are used in a particularly wide variety of applications. Consequently, they are available in many executions and sizes. The standard SKF range comprises the following types:

– single row deep groove ball bearings
– SKF Energy Efficient deep groove ball bearings
– single row deep groove ball bearings with filling slots
– stainless steel single row deep groove ball bearings
– double row deep groove ball bearings
– single row hybrid deep groove ball bearings, see section “Engineering products – Hybrid bearings”
– single row deep groove ball bearings for high temperatures, see section “Engineering products – Bearings and bearing units for high temperatures”
– cam rollers, see section “Track runner bearings – Cam rollers” 
– polymer ball bearings, see section “Engineering products – Polymer ball bearings”

A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as well as by the directions of applied loads they can handle.

Plain bearings use surfaces in rubbing contact, often with a lubricant such as oil or graphite. A plain bearing may or may not be a discrete device. It may be nothing more than the bearing surface of a hole with a shaft passing through it, or of a planar surface that bears another (in these cases, not a discrete device); or it may be a layer of bearing metal either fused to the substrate (semi-discrete) or in the form of a separable sleeve (discrete). With suitable lubrication, plain bearings often give entirely acceptable accuracy, life, and friction at minimal cost. Therefore, they are very widely used.

However, there are many applications where a more suitable bearing can improve efficiency, accuracy, service intervals, reliability, speed of operation, size, weight, and costs of purchasing and operating machinery.

Thus, there are many types of bearings, with varying shape, material, lubrication, principal of operation, and so on. For example, rolling-element bearings use spheres or drums rolling between the parts to reduce friction; reduced friction allows tighter tolerances and thus higher precision than a plain bearing, and reduced wear extends the time over which the machine stays accurate. Plain bearings are commonly made of varying types of metal or plastic depending on the load, how corrosive or dirty the environment is, and so on. In addition, bearing friction and life may be altered dramatically by the type and application of lubricants. For example, a lubricant may improve bearing friction and life, but for food processing a bearing may be lubricated by an inferior food-safe lubricant to avoid food contamination; in other situations a bearing may be run without lubricant because continuous lubrication is not feasible, and lubricants attract dirt that damages the bearings.
