By Larry J. Castleman Larry J. Castleman is Technical Director, Product Development for Trelleborg Sealing Solutions Americas While pneumatic cylinders are often a preferred option for linear actuation in many applications, all portions of the cylinder design must be balanced and work together for efficient and reliable function. One of the more critical components that…
Seals meet aerospace requirements
The Turcon® Variseal® uses a PTFE-based material that directly replaces slipper seals and O-rings in standard grooves in aerospace applications. It resists extreme temperatures, aggressive aerospace fluids, such as synthetic hydrocarbon, petroleum base, phosphate ester, and all types of aviation jet fuels. Additionally, its low coefficient of friction increases sealing load. The seal is specially…

Silicone Seals & Parts For Medical Applications
Simple to complex silicone seals and parts, including O-rings, gaskets, face seals, housing seals, filter seals, custom shapes, and more are available. Made from several technologies, including LIM, they are for microminiature medical applications. Silicone seals come from 0.990 mm (0.09 in.) I.D. or C. S. down to 0.305 mm (0.012 in.) I.D. Apple Rubber…
Illuminate the invisible
Engineers have several choices to sense the presence of objects or information: machine vision systems and photoelectric sensors have been common selections. Recently, manufacturers have enhanced UV sensor capabilities, improving feedback, speed, range, and setup, which make them suitable for many of the same applications as machine vision systems and other sensors. In addition, UV…
Micro Miniature Metal Bellows
Servometer / Precision Manufacturing Group, LLC presents micro miniature electrodeposited nickel bellows manufactured with diameters as small as 0.020 in. (0.5 mm) that are dynamically flexible.

Steel-Disk Seals
NILOS steel-disk seals for grease-lubricated roller bearings contribute to bearing service life. They protect against contaminants in mining equipment exposed to dirt, dust, and debris and minimize bearing friction loss and heat build-up. They also prevent lubricants from leaking. Their non-contact, grease-filled labyrinth sealing elements comprise laminated steel-seal disks and steel cores. The seals resist…
