Hydraulic & Pneumatic Fluid Power Seals
I.D. # 91002 Duration 1.5 Days
This seminar presents the findings of several seal research and development programs, focusing on the "lessons learned" from - and innovative solutions to - seal problems. Attendees will gain insights from numerous R&D programs, including: a large rod scraper evaluation study; experiments evaluating different types of cap seals; and the military's research on 8,000 psi hydraulic systems (the findings of which are equally applicable to lower pressure components). Seal design recommendations applicable to actuators will also be presented. A software program for seal squeeze and gland volume fill (with most adverse tolerances) will be demonstrated and provided to each attendee.
Who Should Attend
This seminar is designed for those responsible for the design of hydraulic or pneumatic components, the selection of fluid power systems, or the sales of hydraulic or pneumatic seals.
Prerequisites
Attendees should have previous experience with seals or basic knowledge of the subject.

Instructor(s): Kelley Fling
Mr. Fling currently teaches fluid power at the college level. He has extensive experience in the fluid power field and was previously the R&D lab manager for a manufacturer of cylinders for the mobile market. He is a former chairman of the SAE A-6 Committee, Aerospace Fluid Power, Actuation, and Control Technologies and has led seal research programs sponsored by each of the three armed services. Mr. Fling holds two seal patents. He received a B.S. in Mechanical Engineering from Texas A & M University and a M.S. in Mechanical Engineering from Southern Methodist University.
