Ball bearing

In 1794, the first commercial installation in the U.S. of ball bearings was made on the weather vane on top of the steeple of the Evangelical Lutheran Church of the Holy Trinity, Lancaster, Pennsylvania. The brick portion of the tower rises 86 feet and includes the bell chamber, above which rises the spire from an octagonal base to a height of 195 feet, upon which was mounted the weather vane. The bearings were of an antifriction roller type, with a pin through them.
