Napoleon Engineering Services: Rigged for Success
For design engineers and purchasing agents alike, bearings can sometimes be like family. Oh, you know - can't live with 'em, canâ™t live without 'em.
The Efficient Drive System
It's a fact that drive systems wouldn't function properly or efficiently without couplings. They quietly go about their business of transferring motion from one drive element to the next. In the PT market today, couplings have the unique challenge of satisfying a variety of customer needs including tighter tolerances, higher speeds and a more versatile selection process.

How To Use a Hand-Held Micrometer to Measure Miniature and Instrument Ball Bearings
For the most accurate measurements, miniature and instrument ball bearing dimensions should be measured with a calibrated air gauge. A good second option is a calibrated optical comparator. On occasion, it may be necessary to use a calibrated, hand-held micrometer to double-check a measurement or for simple verification while working in the field.
