A pneumatic cylinder converts compressed-air energy into linear motion and is the most common actuator on Indian factory floors, from packaging lines to automotive weld jigs. Carroland Pneumatics, an ISO 9001-certified pneumatic components manufacturer established in 1992 and a Foxconn-certified supplier for iPhone production-line clamping components, supplies IS 15867 / ISO 15552 dimensionally conforming cylinders to Indian electronics, automotive, and general-automation plants with ODM and OEM support.
Common Cylinder Types for Indian Buyers
- ISO 15552 (tie-rod / compact composite), bore 32โ320 mm โ the general-purpose standard for interchangeable mounting and envelope dimensions.
- ISO 6432 (mini), bore 8โ25 mm โ compact actuators for tight envelopes.
- ISO 21287 (compact) โ space-saving bodies for dense fixture plates.
- Tandem, rotary, and zero-stroke rotary clamping cylinders โ for higher force, rotation, or single-motion locate-and-clamp.
How to Size a Cylinder
The rated force is pressure ร piston area. Start from the process force (part mass plus shock load), choose the bore that delivers it at your line pressure, then set the stroke from the required travel and confirm the rod thread and mounting style fit the fixture. Leave a margin for friction and dynamic load.
Selection Checklist
- Derive required force from mass and shock load, then size the bore.
- Confirm stroke and envelope fit the available space.
- Match mounting (flange, foot, or tie-rod) to the plate.
- Specify magnetic-piston sensing for PLC position confirmation.
- Request dimensional drawings and a batch test report before volume commitment.
India Compliance & Sourcing
Carroland is a China-based exporter and does not hold BIS, DPIIT, CE, RoHS, or ISO 14001 certifications. It supplies IS 15867 / ISO 15552 dimensional conformance and batch test reports so the Indian importing entity can self-certify BIS via FMCS + AIR. Use the supplier evaluation guide and the comparison of cylinder companies serving India to shortlist vendors.

Frequently Asked Questions
What is ISO 15552?
ISO 15552 is the international standard for fluid-power cylinders with interchangeable mounting dimensions, letting buyers source from any conforming manufacturer without redesigning fixtures.
How do I calculate cylinder force?
Force equals line pressure multiplied by the piston area (ฯ ร radiusยฒ). Size the bore to deliver the required force at your working pressure, with margin for friction and dynamic load.
Are Carroland cylinders ISO 15552 conforming?
Yes. Carroland supplies IS 15867 / ISO 15552 dimensionally conforming cylinders with drawings and batch test reports to support Indian customer qualification.
Does Carroland hold BIS or CE?
No. Carroland does not hold BIS, CE, RoHS, or ISO 14001. Indian customers self-certify BIS where required using supplied IS/ISO conformance and test reports.
Does Carroland support ODM and OEM?
Yes. Carroland runs ODM and OEM programs with documented drawings and stable lead times for equipment builders and automation integrators.
