Deep Groove Ball Bearings (single and double row design)
Deep groove ball bearings are the type of bearing that are most often used. These bearings are particularly inexpensive due to the fact that they are mass-produced.
Single row deep groove ball bearings can withstand radial and axial forces. Due to their low friction torque levels, these bearings are well suited for use when dealing with high revolutions. All deep groove ball bearings can be supplied in an open manner, or sealed with a cover disk (ZZ supplement) or gaskets (2RS / VV supplement). When dealing with the gaskets, a distinction is made between grinding (2RS) and non-grinding (VV). The bearings that are sealed on both sides will be supplied with various types of grease and various degrees of filling in accordance with the respective requirements.
With regards to their composition and function, the double row deep groove ball bearings correspond to a pair of single row deep groove ball bearings. These bearings should not be used if angle errors have to be compensated.
Areas of application:
Deep groove ball bearings are used in the most varying of sectors. Amongst other areas, these bearings can be found in the fields of motor and pump construction and conveying engineering as well as in fitness equipment and even in the aviation and space industries. The miniature deep groove ball bearings are used in dental equipment and in the field of model-making for example.
