Exclusion Seals
Exclusion seals, wipers, and scrapers clean the surface of a retracting rod, removing abrasive particles such as dirt, mud, and ice. This protects the seal and extends service life. The importance of wipers cannot be overemphasized. Often a seal fails prematurely because the wiper wears out long

Pressure-Energized Seals
, the flexible lips are compressed against shaft and walls, increasing sealing effectiveness. The advantage is that the relatively small area in contact with the dynamic surface produces little friction, giving long life and good sealing at high. Pressure-Energized Seals | Machine Design.

Better than metal
transfer a film of PTFE to the shaft and can virtually eliminate wear. PTFE-based rod-guide bushings outperform those made from bronze that can score the shaft over time, eventually wearing the rod wiper seal. The PTFE film that transfers to the shaft tends to enhance sealing. The bushing and seal have

Straight Facts on Blind Rivets
by a flared head and a solid-rod mandrel with a bulbed head that extends from the hollow rivet shaft. It looks somewhat like a nail. To install one, a jaw on a setting tool grips the mandrel, pulls it into the rivet body through a drilled or punched hole in one or more layers of material

Mechanical Motion Keeps Pace
just over a quarter of our audience favors ball screws and lead screws with slides and guides, and following closely behind (at less than 24%) are pneumatic actuators. Almost 18% use primarily direct linear motors/drives. ADVERTISEMENT. Significant challenges among those polled in 2011 are more
