This shutter replaced the two-blade Automat. It was also advertised as the New Automat. Some advertisements show a dial-set arrangement others rim-set. The speed range varies between examples.

Ilex shutters were the first to use a gear train to vary the exposure. The Universal has a slow top speed and is everset. The Acme with a higher top speed has a setting lever. Around 1921 the shutters were re-designed. The casing was streamlined with rim setting of the speeds in place of dial set.

The Ball Bearing was one of the most poplar Kodak shutters. It was made in two forms - No. 0 with three blades and speeds of 1/50, 1/25 and No.1 with five blades and speeds of 1/100, 1/50, 1/25. The No. 1 form had an exposure counter when introduced in 1909, later this was dropped. The No. 0 was introduced in 1912.
