There are single row, double row and four row cylindrical roller bearings. Cylindrical roller bearing SL series with single seal or double seals are double row sealed bearings. One row of rollers and outer ring can be assembled as one non-separatable part. Cylindrical rollers are guided by the rib of inner ring. Outer ring has a solid rib, two locating slots on the outer surface with a lock ring which easily locate the bearing axially. The bearing housing width is usually smaller than that of the bearing to reduce required room in the axial direction. As locating bearings, this type of bearing can accommodate axial load in both directions with bigger width, it can also accommodate upsetting momet. Cylindrical roller bearing is mainly applied in electrical motors, machine tools, oil production, steel mills, loading and moving machineries and other industrial machineries. Cylindrial Roller Bearings feature high radial load because the rollers and raceway are in linear contact. These bearings are suitable for applications that involve heavy radial and impact loading. We can produce extra-large size Cylindrical Roller Bearings, such as: Single-row Cylindrical Roller Bearings(ID260--1900) & Double-row Cylindrical Roller Bearings(ID260--1500)
