7      SPHERICAL ROLLER BEARINGS



                 WA222B Series                          Sealed self-aligning roller bearings


                FOR USE WITH SNG SERIES HOUSINGS





                SPECIAL CHARACTERISTICS

                • Highly efficient at preventing infiltration of contaminants.
                • Can be integrated into standard SNG plummer blocks.
                • Although bearings are sealed, relubrication is possible.

                • Bore and outer diameter dimensions are equivalent to 222B series, width dimensions are wider.
                  (<100mm bore equivalent to 232 series).
                • Internal design is equivalent to 222B series, therefore basic load ratings correspond to 222B series.
                • Outer rings are provided with lubrication groove and holes as standard.
                • Seals are designed to maintain ideal contact pressure with inner ring ribs, under misalignment up to ±0.5˚.
                • Bearings are supplied packed 25-35˚ with Lithium/mineral oil grease (Alvania #3).
                • Allowable operating temperature range -25 to120˚C.
