MINIATURE BALL RACE BEARING SYSTEM FOR CLOCKS, ETC.

© Mike Dennis 2002

 

 
 

A ball race  Ø5 x Ø8 x 2.5mm is fitted into a Meccano sized boss mounted on a 3 hole strip to provide a bearing for clocks or and other mechanisms where very low friction is required. The Ball race OD is 0.315" (8mm) and the Meccano axle size adapter is fitted with an 8 B.A. grub screw


 

Michael Adler purchased 10 from me when I first developed them in 2002 to compliment the HMS clock hands system described later.
