custom cylinders

Are standard cylinders insufficient for your application?

Our custom cylinders combine bespoke design with maximum functionality – robust, precise, and specifically developed for exceptional requirements that standard solutions cannot meet.

Do you need special dimensions, large diameters or strokes, special mountings, or have to consider specific outdoor conditions? Then KONSTANDIN is the right partner for you!

Our range of services primarily consists of custom cylinders, which we develop and manufacture in our own CNC machining center and assemble using our trained personnel.

Reduce your costs with tailor-made solutions!

Get an overview of our diverse range of special cylinders: from miniature versions with a 12 mm diameter to XXL dimensions with a 500 mm piston diameter. We also offer complex multi-stage systems such as tandem cylinders and high-force cylinders, underwater cylinders for chlorinated water, and ATEX-compliant versions for the petrochemical industry.

Special operating conditions require innovative solutions: high-temperature variants up to +120°C, outdoor-suitable cylinders with seawater coating, and combinations with integrated rotary unions for rotating applications.

Upon request, we will gladly apply your own customer label – guaranteeing your after-sales service backed by over 30 years of development experience.
