In 1998 Robinson Helicopter set out to find the best piston seals for the three servos powering the hydraulically boosted controls of its R44 helicopter.
Robinson Helicopter of Torrance, California is one of the world's foremost manufacturers of civilian helicopters.
Not only do Robinson's aircraft offer excellent value for the money, their hydraulic control systems are also leak free - thanks to seals from worldwide aerospace sealing developer and manufacturer Busak + Shamban.
The vision of company founder Frank Robinson was to create a small, low-cost, reliable helicopter.
Robinson Helicopter has steadily carved out an impressive position in its market.
In 2005, it manufactured 806 civilian helicopters, more than any other company in a single year.
The helicopters are designed for low maintenance, which makes them cheaper to operate.
Just as customers seek reliable helicopters, the helicopter maker seeks reliable parts.
And for hydraulic seals, Robinson found the perfect match in Busak + Shamban.
In 1998 Robinson began working with Busak + Shamban to find the best piston seals for the three servos powering the hydraulically boosted controls of its R44 helicopter.
At the piston rod, Robinson uses Busak + Shamban Excluder, its Plus Seal II seal and Slydring.
At the input valve, a low-friction seal in proprietary Turcon PTFE based material, prevents feedback to the pilot.
"It's a partnership", says Matt Flanagan, Director, Aerospace Segment, Americas.
"We've worked hand-in-hand during product development, making recommendations about the surface finish of the hardware".
"We've matched the operating conditions with the appropriate materials using standard products".
Pete Riedl, Robinson's Vice President, Engineering comments on the success of the Busak + Shamban solution: "We are able to create a hydraulic system that doesn't leak", says Riedl.
"It's a huge benefit".
