scotch yoke pneumatic actuator adopts rollingfriction instead of sliding friction, the aluminium alloy piston doesn't contact with the steel shaft directlywhich greatly reduced thewearing of transmissionparts.
The smooth and wear-resistant shaft sleeve andmulti-point guide seal, improve the sealing performanceand quiding performance make the piston and scotch yoke more stable during the movement process, andthe service life can
be reached more than1000000times.
