Hot Sale for PTFE Packing with Aramid Corner Supply to Berlin

PTFE packing with aramid corner is made from aramid yarns impregnated with PTFE, while the friction faces are made of PTFE yarns. This structure enhances the lubrication ability of aramid fiber and improves the strength of the pure PTFE.

Technical Data Sheet

 Application Area

It affords longer service life under severe conditions which conventional asbestos packing can bot provide satisfaction, such as mine, tin ore, paper pulp, feed water pump of power stations, etc.

We have developed a new method for puppeteers to remotely control mechanical characters without the use of motors. The pair of robot arms shown in this video are connected only by flexible pneumatic tubing. There are no pumps, valves, sensors, motors, or electronic controllers used. The passive connection between the two arms is made entirely by air pressure, allowing a large separation between the character and the puppeteer, and tight bends in the air control lines. The key technology is an ultra-low friction pneumatic transmission, enabled by the use of rolling diaphragm seals, instead of traditional sliding o-ring seals. If motorized, the transmission allows the motors to be placed in the body, rather than mounted to the arm, leaving the arms much lighter, and capable of faster and more graceful motion. The robot arm in this video was designed and built by Tianyao Chen, Peter Whitney, and Jessica Hodgins.
