October 2021 - Trelleborg Sealing Solutions, one of the world’s leading developers, manufacturers and suppliers of precision seals, bearings and custom-molded polymer components, launches a new line of high-quality polyurethane (PU) seals in inch sizes for light-, medium- and heavy-duty hydraulic cylinders and other linear hydraulic applications.
The PU line, comprising piston, rod, and buffer seals and wipers, is designed for use in original equipment and for retrofit to common American groove sizes to accommodate the manufacture and refurbishment of hydraulic cylinders in fluid power and off-highway applications.
Beth Figliulo, segment manager for Fluid Power, said: “The PU product line complements our existing polytetrafluoroethylene seal package for piston and rod seals. With a wide range of common PU seal sizes in stock and available for quick delivery, we now offer the market a single source for fluid power and off-highway sealing solutions backed by local engineering support, R&D resources, and testing facilities.
“We also provide a variety of digital tools to help design engineers specify sealing solutions for both dynamic and static applications. In addition, our logistics and ServicePLUS centers provide full-service options for assembly and kitting. That means our customers truly receive everything they need from one source, whether that’s seals, technical support, or value chain assistance.”
The PU seals and wipers are suitable for common hydraulic applications with typical pressures of 3,000 psi, temperatures from -30 °F to +230 °F and speeds up to 1.5 ft/s using standard mineral oils. Zurcon premium-grade PU material options are available for synthetic oils, fire-resistant fluids and biodegradable fluids.
Trelleborg supplies PU seals directly to customers to ensure quality service and supply. Trelleborg manufactures PU seals, including the well-established Zurcon U-Cup RU9 and Buffer Seals, at multiple ISO 9001, ISO 14001, and IATF 16949 certified sites across the Americas, APAC, and Europe. The PU seals meet required, stringent regulations, including REACH SVHC, Annexes XIV and XVII, RoHS III, POP 2019/1021, CA Proposition 65, Conflict Minerals, and GS-Mark, and are Phthalate-Free.
