Trelleborg Takes the Shock Out of Cycling

It Supplies Leading High-End Bicycle Shock Absorber Manufacturer With Advanced Seal Solutions

FORT WAYNE, IN--(Marketwire - July 14, 2010) -  Trelleborg Sealing Solutions and A-Pro Tech Co. Ltd., a Taiwanese company that specializes in high-end shock absorbers for bikes, began a relationship 10 years ago when Trelleborg helped A-Pro solve a problem with leakage from rear shock absorbers.

That story of success continues today with the development of new configurations for shock absorbers for heavier duty applications, such as in downhill and free-ride models, which work at much higher pressures. Trelleborg is employing the Turcon® AQ Seal®, which has given exceptional performance in industrial applications that are also subject to high-pressure spikes.

That original solution that led to a decade-long partnership replaced existing seals with a complex configuration of specialized seals including a piston ring in Turcon®, Trelleborg Sealing Solutions' proprietary PTFE based sealing material, and U-Cup in Zurcon®, its proprietary Polyurethane based sealing material. The sealing system has excellent overall sealing characteristics, key in the effective performance of A-Pro's shock absorbers in difficult off-road and mountain terrain conditions. It also ensures exclusion of external media (the ingress of which is a potential cause of failure) and meets zero leakage requirements.

"Trelleborg Sealing Solutions understands the bicycle market and can provide us with cost-effective sealing," says Andrew Huang, vice president of A-Pro. "The systems are designed specifically to our requirements, meeting our needs exactly."

A-Pro Tech Co. Ltd was established in 1982, originally manufacturing parts for and assembling BMX bikes. In 1986 it began concentrating on mountain bikes and road racing frames. The company has several brands including X-Fusion, its high-end shock absorber range. The popular O2 air shocks are specified on several major bicycle brands.
