Ram Single Acting Aluminium (RSA)


The OYS standard aluminium cylinder range has been engineered to the highest standard, combining excellent strength to weight ratio with prolonged corrosion resistance and outstanding service life.

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

A variety of standard, long and flattener 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-0006-0150, with larger sizes available on request.
