Mechanical Lock Single Acting Aluminium (MSA)


The OYS standard aluminium mechanical lock cylinders have 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 robust and reliable performance in the harshest environments.

The lock nut traverses the threaded rod section to allow a position adjustable mechanical lock that resists movement of the rod without the need for cylinder holding pressure.

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