Frequently Asked Questions

What is ISO 15552 pneumatic cylinder standard?

ISO 15552 (previously ISO 6431 and VDMA 24562) is the international standard for roundline pneumatic cylinders with profile barrels. It defines: mounting dimensions (bore-to-mounting bolt patterns), piston rod thread sizes, port positions, and sensor groove dimensions. The standard ensures interchangeability between manufacturers - any ISO 15552 cylinder mounts identically and has the same performance characteristics regardless of brand. The profile barrel provides more strength than tie-rod cylinders and allows sensor mounting in a groove along the barrel.

What is the difference between double acting and single acting cylinders?

Double acting cylinders use air pressure on both sides of the piston to produce force in extension and retraction - providing full force in both directions. Single acting cylinders use air pressure only for extension (or retraction), with a spring providing the return force. Single acting cylinders are used for simple push or pull applications where return force requirement is low (clamping, ejecting). Double acting cylinders are preferred for precision positioning, variable load, and higher force requirements.

How do I select the right bore size for an ISO 15552 cylinder?

Bore selection depends on: the force required (Force = Pressure x Area), operating pressure available, stroke length needed, and space constraints. To select: determine required force at operating pressure; apply a safety factor of 1.3-1.5x; calculate required piston area; select the smallest bore that provides at least 1.3x the required force. For most industrial applications, 5-6 bar operating pressure with 80-100mm bore provides good force-to-size ratio. For high force requirements, consider 10 bar pressure and larger bore sizes.

What mount styles are available for ISO 15552 cylinders?

ISO 15552 cylinders offer multiple mounting styles: Foot Mount (front or rear foot, for straightforward linear mounting); Flange Mount (front or rear, for higher moment loads); Rear Clevis (ISO MP2, with or without spherical bearing for angular compensation); Front Clevis (ISO MP4); Trunnion Mount (ISO MT4, for pivoting applications); and Centre Trunnion (ISO MT4, adjustable pivot point). The mounting style should be selected based on the mechanical setup and whether the cylinder needs to compensate for misalignment.

Can ISO 15552 cylinders be used with magnetic position sensors?

Yes, ISO 15552 cylinders have a standard T-slot groove along the barrel profile for magnetic piston position sensors ( reed or solid-state). These sensors detect the position of the magnetic ring on the piston without physical contact, enabling non-contact position feedback. Common sensor types: reed switches (simple on/off), solid-state switches (PNP/NPN), and analog sensors (0-10V or 4-20mA output for position measurement). Sensor mounting brackets are manufacturer-specific but generally standard across the ISO 15552 range.
