Fig. 2. Example of a noncontact seal used for a ball bearing. Noncontact seals: A noncontact seal (Fig. 2) produces much less friction (if any) and heating than a contact type. Unfortunately, noncontact seals also allow lubricant to leak out of the bearing chamber and liquid, and permit physically small contaminants to enter. Fig. 3.

Although bearings had been developed since ancient times, the first modern recorded patent on ball bearings was awarded to Philip Vaughan, a Welsh inventor and ironmaster who created the first design for a ball bearing in Carmarthen in 1794. His was the first modern ballbearing design, with the ball running along a groove in the axle assembly.
