This bearing supports axial loads acting from both directions while locating a shaft precisely under combined load conditions. The angular contact ball bearing 234428-M-SP is a double direction design, separable, built to restricted tolerances. Bore diameter is 140.0 mm, outside diameter 210.0 mm, and width 84.0 mm, giving the seat dimensions for shaft and housing fit. Net mass is 8.791 kg. The cage is designated M, indicating a machined cage construction. Being separable allows the rings to be mounted independently, which simplifies fitting onto the shaft and into the housing during assembly. The restricted tolerances support applications requiring accurate axial positioning and reduced running deviation. As a double direction type, it accommodates axial forces from either side of the bearing while being mounted together with a radial bearing that carries the radial load. Dimensional and constructional equivalents are SKF 234428 and SKF 234428BM1/SP.
