International Fluid Power Exposition & Conference

Produced by the National Fluid Power Assoc., The International Fluid Power Exposition and Conference is one of the largest fluid power exposition and technical conferences held in North America. Exhibitors and technical conference participants from countries around the world will bring a collective expertise in hydraulics and pneumatics. Leading component and systems designers and application experts from Europe, Asia, and the United States will be present.

Recognizing the importance of hydraulic fluids as a vital component in hydraulic systems, the IFPE will hold a special Hydraulic Fluids Symposium in conjunction with its Technical Conference. Speakers will cover a broad range of topics as they examine the current technology for high-water-content fluids, vegetable oils, and conventional mineral-based fluids.

A Comparative Motion Control Technology Symposium will explore the issues of motion control engineering in different actuation medias including electrohydraulics, electropneumatics, and electromechanical. This symposium will be useful for application, manufacturing, and machine design engineers, as well as distributors and manufacturers.

New to the conference, "Hydraulic System Maintenance and Troubleshooting" will help attendees learn to develop and implement preventive maintenance programs, assign personnel responsibilities, and select program software. General systems maintenance tips, including some on fluids and filter maintenance, as well as specific precautions for cold weather will be covered.

"IFPE attendees will have a unique opportunity to explore a wide range of innovations and all motion control technologies at one combined event," says William Prueser, IFPE's Director of expositions. Conference organizers expect more than 300 exhibitors and 100 presentations.


The MegaCrimp(TM) coupling is leak resistant and easy to crimp. It has a patented "C" insert, attached to the ferrule, that freely encases hoses of different constructions and wall thicknesses. During crimping, only the ferrule takes on the traditional octagonal shape formed by the die fingers. The "C" insert remains round and evenly distributes crimp forces, producing a tight concentric seal.

Pneumatic cushion seals dampen the pistons in cylinders and take over the function of mechanical check valves. The V6 Cushioning Seal housing is nearly equal to that of an O-ring, installs easily in small housings with simple grooves, has consistent cushioning properties, and is available in both metric and inch sizes. V6 Cushion Seals are available in urethane, nitrile, and fluorocarbon. The PP Cushion Seal has high cushioning consistency due to automatic centralizing, even in the case of misalignment of the cushioning spear to the cylinder head. The PP cushioning seal is for metric studs in nitrile.

BTL-3 linear position sensor achieves accuracy of plus or minus 0.0015 inches over lengths up to 100 inches, with resolution and repeatability of 0.0007 inches. It is shock-resistant and sealed to IP 67 requirements, and immune to chips, dirt, oil, and wear, making it useful for machine tools, automated assembly equipment, measuring machines, and other demanding linear motion control applications. The BTL-3 has synchronous serial interface, a signal format supported by most major controllers, including NC. Because signal processing and serial conversion are performed internally--with no need for a separate, external processor card--the sensor connects directly to the host controller. Absolute output signal renders the transducer immune to power failures, eliminating the need to mechanically re-home after an outage.
