Ball bearing - Wikipedia

His was the first modern ball-bearing design, with the ball running along a groove in the axle assembly. Jules Suriray, a Parisian bicycle mechanic, designed the first radial style ball bearing in 1869, which was then fitted to the winning bicycle ridden by James Moore in the world's first bicycle road race, Paris-Rouen, in November 1869.

This longitudinal play may increase to 2 mm as a result of wear on the lock jaw or wearing ring.

Bearing Measurement Instrument - LabMaster Universal from ...

Ring deflection is in a direction that does not directly affect the measurement. Vertical mounting of the bearing means that the weight of the outer ring will add to the downward applied force and subtract from the upward applied force. Horizontal mounting of the bearing ensures that the bearing load is unaffected by the outer ring weight.
