Nelson Ball Bubble Pendant - Herman Miller Store

The Bubble Lamp (1952) began as a contemporary version of silk-covered ball pendant lights. Inspired by the process the military used to mothball ships, design director George Nelson fashioned a circle from steel wire, placed it on a spinning turntable, and then shot translucent plastic at the sphere until it was fully covered.

Ball End Mills | McMaster-Carr

Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.

1. ISO Dimensional system and bearing numbers

The bore diameter symbol is a number which is 1/5 of the bore diameter dimension when bores are 20 mm or greater. For instance, if the bore diameter is 30 mm then the bore diameter symbol is 06. However, when the bore diameter dimension is less than 17 mm, then the bore diameter symbol is by common practice taken from Table 1. Although
