The 53300+U Series single-direction self-aligning thrust ball bearings in the medium series combine enhanced axial capacity with angular misalignment compensation. The sphered washer interface accommodates shaft-to-housing angular deviations while maintaining uniform ball loading. Ideal for inclined screw conveyor thrust bearings and self-aligning vertical pump thrust assemblies.
