The design and characteristics of single-row deep groove ball bearings of the wide series are analogous to those of standard single-row deep groove ball bearings. The difference is that they belong to a different width series and are therefore wider than the corresponding bearings.
SLF produces wide deep groove ball bearings in the 630.., 622.. and 623.. series, with and without seals. The standard sealed version has sealing washers on both sides (suffix .2RSR).
