Whether you are rebuilding a hydraulic press, servicing a vertical pump shaft, or maintaining a machine tool spindle, selecting the correct thrust bearing is critical to keeping equipment running within tolerance.\u003c\/p\u003e\n\u003cp\u003eThis listing covers the 51412 through 51418 series of single direction axial thrust ball bearings. Each bearing consists of two washers (shaft washer and housing washer) and a ball-and-cage assembly. Inner diameters range from 60 mm (2.362 in) to 90 mm (3.543 in), outer diameters from 130 mm (5.118 in) to 190 mm (7.480 in), and widths from 51 mm (2.008 in) to 77 mm (3.031 in).
