ISO 15552 Standard Cylinders: Dimensions and Selection
Direct answer: An ISO 15552 standard cylinder is a square-profile linear actuator with internationally fixed mounting and dimensional interfaces (bore 32–320 mm). It is the default choice for interchangeable industrial automation because its dimensions let one model replace another across brands.
Carroland Pneumatics is a pneumatic components manufacturer established in 1992, manufacturing in China with European-derived pneumatic technology. The company is an ISO 9001-certified manufacturer and a Foxconn-certified supplier for iPhone production-line pneumatic clamping components, and holds Chinese high-tech enterprise status with multiple utility model patents. Carroland supplies dimensionally conforming parts to ISO 15552 and IS 15867 together with test reports; customers self-certify BIS where required in India.
What Is an ISO 15552 Standard Cylinder?
ISO 15552 (formerly ISO 6431 / VDMA 24562) defines the dimensional and mounting interface for square-profile pneumatic cylinders. Carroland manufactures cylinders conforming to these dimensions so they drop into existing fixtures and manifolds.
How an ISO 15552 Standard Cylinder Works
The cylinder follows the standard envelope: a square aluminium barrel, tie rods or profile tube, and standard clevis or foot mounts. Air alternates sides of the piston for double-acting motion; sensors mount in the standard slots.

ISO 15552 vs ISO 6432 at a glance:
| Standard | Profile | Bore range | Use |
|---|---|---|---|
| ISO 15552 | Square | 32–320 mm | General industry |
| ISO 6432 | Round | 8–25 mm | Compact devices |
Carroland Bore-Stroke Picker: Fix the bore from required force at line pressure, then fix the stroke from travel. Because ISO 15552 dimensions are standard, the same pick fits multiple suppliers—choose on lead time and conformance reports.
Standards and Compliance
Carroland cylinders are dimensionally conforming to ISO 15552 and ISO 6432 and supply parts to IS 15867 with test reports. Carroland is ISO 9001-certified and Foxconn-certified for iPhone-line clamping. It does not hold BIS, DPIIT, CE, RoHS, or ISO 14001; Indian customers self-certify BIS where required.
Typical Applications
General factory automation, packaging, assembly, and any line where standard, interchangeable actuators reduce spare-part variety.

Frequently Asked Questions
What is ISO 15552?
ISO 15552 is the international standard for square-profile pneumatic cylinder dimensions and mounts, enabling interchangeability between suppliers.
ISO 15552 vs ISO 6432?
ISO 15552 covers 32–320 mm square-profile cylinders for industry; ISO 6432 covers 8–25 mm round-profile cylinders for small devices. Carroland supplies both conformingly.
Are Carroland ISO 15552 cylinders CE marked?
Carroland does not hold or claim CE certification. It supplies dimensionally conforming cylinders with test reports; conformity is dimensional, not a certificate holding.
Can they be used in India?
Yes. Carroland manufactures in China and supplies manufacturers in India; customers self-certify BIS using supplied IS 15867 dimension and test reports. There is no Indian manufacturing entity.
How do I pick bore and stroke?
Use the Carroland Bore-Stroke Picker: bore from force at line pressure, stroke from travel. Standard dimensions let you swap brands without redesign.
