Piston rod - Import export

The stopper cylinders are developed to stop or block moving parts, e.g. in an assembly line. The large dimensioned piston rod also allows use as a stand-by stop device.

The rod lock BS is a mechanical device for securely locking the piston rod in any position in the event of a pressure drop. For cylinders with a design according to ISO 15552 and 6432 VDMA.

Cylinder with double piston rod as anti-rotation device against linear movement of the piston rod. Design based on ISO standard. Available sizes diameter: 32, 40, 50, 63, 80, 100 mm.

Single-acting pneumatic cylinder with two parallel working piston rods made of brass, nickel-plated or stainless steel.

Double-acting pneumatic cylinder with piston rod in a special design for use in a press-in device.s

Large-volume pneumatic cylinder with through-piston rod for use as a die-cushion press balancing cylinder in a mechanical press.

The rod lock BS is a mechanical device for securely locking the piston rod in any position in the event of a pressure drop. With manual unlocking.

Double-acting special cylinders with a customer-specific base flange, pre-assembled with fork mounts with flexible rubber bellows over the piston rod to protect against coarse dirt and aggressive environments. Specially designed for use in commercial vehicles or agricultural machinery.

The CD short-stroke cylinders have been developed to ensure high performance in a very small space. Sensors can be integrated in the cylinder housing. Available versions: single / double acting or with through piston rod.

Cylinders with Ertalyte piston rods are particularly suitable for use in the food and chemical industries. High resistance to acids, good electrical insulating properties, wear resistance, excellent sliding properties and even resistance to gamma rays or X-rays allow it to be used under difficult conditions. For the use of pneumatic cylinders in environments with radioactive radiation, we also stock cylinders with radiation-resistant seals.

The X‑ring is a continuous, seamless vulcanized ring with a special profile which is derived from four O‑rings arranged in a square crosssection.The particular advantage of the X‑ring is that it cannot roll or twist. The squeeze required to maintain an effective seal is also relatively low.The X‑ring is used in mechanical and automotive engineering, preferably as a static radial or static axial seal. Other applications are for linear or rotary motion of plungers, pistons, tappets, dampers and valve, bearing and piston rods, etc.

Due to their design, Vibrophores have been used in the past solely as dynamic materials testing machines to determine durability with regard to fatigue life and fatigue limit, for example for fatigue testing to DIN 50100 (S-N curve) under tensile, compression, pulsating and alternating loads. The new generation of ZwickRoell Vibrophores can be used as both dynamic and full-fledged static materials testing machines that accommodate test loads up to 1000 kN. Typical applications are material fatigue tests and durability tests on standardized specimens and components (for example, piston rods, crankshafts, and screws) and production and quality control of components exposed to dynamic loads during their service lives, such as concrete and reinforcing steel, as well as quasi-static tensile and compression tests and fracture mechanics tests on CT and SEB specimens.
