Philip Vaughan was a Welsh inventor and ironmaster who patented a ball bearing race for carriage axle-trees in 1794. He was a proprietor and agent of iron foundries at Carmarthen and Kidwelly. He married Elizabeth Griffiths in 1793. In 1800 Vaughan signed a copartnership deed with John Morgan Junior, William and Thomas Morris, and William Morgan, and started a 21 year lease for the Carmarthen rolling mills from John Morgan Sr. The lease included Kidwelly Forge, Blackpool Forge, the tin mills and various clauses for the watercourse leading to the Carmarthen works. He died in 1824. This information is condensed from the Wikipedia entry.
Vaughan's ball race had no cage to separate the balls. The bearing is described and placed in historical context in a NASA Technical Memorandum
