Deep groove ball bearings are among the most widespread bearing groups. They feature a simple design. Their principal advantage is the ability to carry both radial and axial loads, even at high rotational speeds.

Depending on requirements, deep groove ball bearings can be supplied in various designs, such as reduced or increased clearance, higher accuracy classes and special cages suitable for relatively high rotational speeds. They can also have various construction variants, including protective shields of type 2Z or rubber seals of type 2RS, and an N-type groove in the outer ring for locating the bearing axially in the housing using an R-type ring.

With such a wide range of construction and quality variants, deep groove ball bearings are used throughout industry. Enclosed deep groove ball bearings with protective shields 2Z or rubber seals 2RS are filled by the manufacturer with a suitable operating grease sufficient for average operating conditions throughout their service life. Standard enclosed ball bearings can operate at temperatures from -30°C to +100°C. For difficult conditions (high rotational speed or temperature), the manufacturer can supply bearings with special grease and an appropriate fill level. Enclosed ball bearings substantially simplify bearing arrangements and make them more compact. These bearings do not require relubrication, greatly simplifying servicing during operation. Enclosed bearings are not recommended where the outer rings rotate, because there is a risk of grease leakage even at relatively low rotational speeds. Enclosed bearings must not be washed or heated before installation.
