When A-Pro Tech Co. Ltd., a Taiwanese company that specializes in high-end shock absorbers for bikes, had a leakage problem with rear shock absorbers, Trelleborg Sealing Solutions provided an answer with a configuration of specialized seals including a piston ring in Turcon®, a proprietary PTFE based sealing material, and U-Cup in Zurcon®, a proprietary Polyurethane based sealing material.
Ten years later, Trelleborg continues to solve sealing problems for the Taiwanese company. The latest is 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. The Turcon® AQ Seal® gives exceptional performance in industrial applications that are also subject to high-pressure spikes.
The sealing system has excellent overall sealing characteristics, key to 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.
A-Pro Tech Co. Ltd
A-Pro was established in 1982, originally manufacturing parts for and assembling BMX bikes. The company has several brands including X-Fusion, its high-end shock absorber range.
