Round cylinder according to ISO 6432

Standard based cylinders

Festo round cylinders to ISO 6432 are double-acting pneumatic cylinders in round-body form, standardised to the international interface and mounting dimensions of ISO 6432. The DSNU series covers bore diameters from 10 to 32 mm and is available in stroke lengths from 10 mm to over 200 mm. The standardised dimensions allow cylinders from different manufacturers to be interchanged without any design modifications.

The suffix -P-A denotes bilateral end-position cushioning and magnetic piston; the variant -PPV-A adds adjustable cushioning for higher piston speeds. The compact round profile is particularly suited to mounting with flange nuts or clamp bands in confined installation spaces.

⚙ ISO 6432 compliant - globally compatible interface dimensions, interchangeable across manufacturers

↕ Bore Ø 10-32 mm - stroke lengths from 10 mm to over 200 mm in the DSNU range

✓ End-position cushioning - fixed cushioning (P) or adjustable cushioning (PPV) depending on variant

⚡ Magnetic piston (A) - compatible with inductive and magnetic position sensors

⬡ Compact round profile - mounting via flange nut, clamp bracket or pivot bearing

Suffix	Meaning
DSNU-10-...-P-A	Ø 10 mm, bilateral cushioning, magnetic piston
DSNU-16-...-PPV-A	Ø 16 mm, adjustable cushioning, magnetic piston
DSNU-20-...-P-A	Ø 20 mm, bilateral cushioning, magnetic piston
DSNU-25-...-P-A	Ø 25 mm, standard round cylinder ISO 6432
DSNU-32-...-P-A	Ø 32 mm, largest DSNU bore size

Selection is governed by bore diameter (force at operating pressure), stroke length, and cushioning requirement. Variant PPV is recommended when piston speed would cause hard end stops with fixed cushioning P.

Typical applications: Assembly and pick-and-place machines with limited space, handling technology (gripping, pushing, clamping), packaging machinery with short to medium strokes, fixture construction in series assembly, and retrofit projects where ISO 6432 dimensions are required for drop-in replacement.
