Chicago, Ill.Earlier in 2018, the U.S. Patent and Trademark Office awarded PTDA a Class 16 registration mark for its Power Transmission Handbook, a text book first published in 1969 and now in its fifth iteration, packed with content for unbiased product training on 17 categories related to power transmission/motion control (PT/MC) products. Chapters include: fundamentals, bearings, belt and chain drives, clutches & brakes, conveyors & components, coupling & U-joints, gears, hydraulics and pneumatics, linear motion, motors, adjustable speed drives, controls & sensors, sealants & adhesives, accessories, lubrication and vibration analysis.

The companion Power Transmission Handbook Workbook and Answer Guide helps teachers/trainers to test their students and provides an interactive way to learn the content from the Power Transmission Handbook.

Each chapter from the Power Transmission Handbook is available as individual password-protected PDF files in English and Spanish for those looking to teach or access content from specific chapters.
