Single-direction thrust ball bearing

Geometry

Single-direction thrust ball bearing, 511, 512 and 513 series, bore up to 50 mm. Bore d, outside diameter D, height T, shaft washer outside d1, housing washer bore D1, washer thickness t and chamfer r are sourced and make the fit. detail = "full": two washers with raceways and the balls between them. The rolling element size and count, shoulder heights and clearances are proportions for looks, not for design, and never change the fit dimensions. The cage is not drawn. detail = "simple": one solid ring. Axis along Z, centred on the origin.

For the fit: the sourced dimensions below. For looks only, not for design: every other proportion named above.
