In 1936, an ingenious New England inventor produced a tiny ball bearing to replace a jewel in a family heirloom. Winslow Pierce not only repaired his father’s watch, he founded an entire industry. His industry made possible instrumentation that travels millions of miles into space and settles softly and accurately on a distant planet; dental handpieces that operate painlessly at half a million revolutions per minute; aircraft that navigate precisely through darkness and adverse weather. Literally hundreds of various devices employ the millions of ball bearings produced every year. Some...

Carriage Bearings Guide Bearings Close control of carriage bearing radial play and run-out results in accurate positional control of carriage and way assemblies. Smooth opration is assured by careful control of OD finish and roundness. Greater accuracy, stabilily and load capacity may be achieved by integrating components or incorporating the double row feature. Guide bearings provide an economical alternative to machining and assembling individual components in applications such as wire guides, plotters, printers and cable or belt drive Systems.

Gyro OpticsAssemblies Extensive exprience worktng with metalMc and non-metallic materials are combined with prcision grind-ing, machining and asserrtbly skilIs to produce Gyro Optics assemblies, sub-assemblies and components. Th驨se optical/mechanical assemblies are routinely built with gimbal axis and spin axis intersection tolrances of less than .0002 inches. Basic pr魩cision bearing technology is applied to select and match bearings to each other and the mating hardware. Figure 38-1͗Gyro.
