51104 Single Direction Thrust Ball Bearings

51104 The 51104 is a thrust ball bearing from the 511 series, designed with a 20 mm bore diameter to support axial loads in a single direction. Thrust ball bearings use ball elements between two grooved washers (shaft and housing washers) to handle forces parallel to the shaft axis. These bearings are commonly used in automotive transmissions, machine tool spindles, and other rotating applications where space is limited and predominantly axial loads must be supported. They are not designed to carry radial loads and typically require support from separate radial bearings. 51104Bore/Inner Diameter Inch: 0.787 Bore/Inner Diameter mm: 20.0 Outside Diameter Inch: 1.378 Outside Diameter mm: 35.0 For large orders ($2000+) please inquire by email.
