Ram Single Acting Stainless (RSS)


The OYS standard stainless steel cylinder range has been engineered to the highest standard, ensuring our cylinders are both beautiful and created from optimum materials to ensure serviceability, longevity and corrosion resistance.

Careful selection of marine grade stainless steel, high strength Duplex and aluminium bronze, coupled with proven in-house design and manufacturing ensure a robust and reliable performance in the harshest environments.

A variety of standard and long stroke cylinders can be supplied to suit any tensioning application. Should our standard options not exactly match your needs, then OYS’s in-house engineers can customise to better fit your application.

Standard cylinders are available from sizes-0012-0150, with larger sizes available on request.

Solutions for load holding backstays and reverse porting arrangements are also available on request.
