Support rollers are either needle roller or cylindrical roller bearings with an extra radically thick outer ring. Depending on their series, support rollers may be either separable or non-separable radial bearings.Support rollers are usually exposed to minor misalignments during operation. To minimize the negative effects of such misalignments, support rollers are more frequently used with spherical outer rings.Our support rollers with cylindrical outer diameters are indicated by an 'X' suffix. producing area:China
