An arrangement for supporting one or more bearings of a crankshaft assembly of a hydraulic fracturing pump includes a frame and one or more bearing supports. The frame is of a first material and defines one or more bearing support profiles. The bearing supports are of a second material different from the first material of the frame. The bearing supports are cast-in-place within the corresponding bearing support profiles of the frame and are configured to be in contact with an outer race of the corresponding bearings of the crankshaft assembly. Compared to the first material of the frame, the second material of the bearing supports is more effective at preventing slippage of the bearings.
