Rotary Clamping Cylinders: Clamp and Rotate in One Actuator
Direct answer: A rotary clamping cylinder is an actuator that first clamps a workpiece with a linear stroke and then rotates the clamp arm to a locked position. It merges two motions into one body, simplifying fixtures that need both hold and swing.
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 a Rotary Clamping Cylinder?
Rotary clamping cylinders use a piston driving a cam or rack to produce a clamp-and-rotate sequence. Carroland offers rotary clamping cylinders and the related zero-stroke rotary clamping cylinders for applications from general fixtures to 3C automation.
How a Rotary Clamping Cylinder Works
Air drives the piston; a mechanism converts travel into clamp force then rotation of the arm. On exhaust the arm retracts and unlocks. Sensors in standard slots confirm position.
a Rotary Clamping Cylinder Types and Selection
Rotary clamping vs zero-stroke rotary clamping:
| Feature | Rotary clamping | Zero-stroke rotary clamping |
|---|---|---|
| Linear stroke | Longer | Near-zero |
| Body height | Medium | Low |
| Use | General clamp+rotate | Space-limited 3C |
Carroland Clamp-Angle Matrix: List the required clamp angle and height budget, then pick rotary clamping for general use or zero-stroke for minimal height. Lock the angle in the fixture drawing to avoid mis-set arms.
Standards and Compliance
Carroland rotary clamping cylinders are dimensionally conforming to ISO 15552 and supplied 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 using IS 15867 reports.
Typical Applications
Machining fixtures, welding jigs, electronics assembly, and any station needing clamp plus swing in one actuator.

Frequently Asked Questions
What does a rotary clamping cylinder do?
It clamps a part with a linear stroke and then rotates the clamp arm to a locked position, combining two motions in one actuator.
Rotary clamping vs zero-stroke rotary clamping?
Rotary clamping has a longer linear stroke and medium height; zero-stroke rotary clamping minimizes stroke and height for space-limited 3C fixtures.
What bore sizes are typical?
Carroland rotary clamping cylinders commonly span 25–63 mm bore, sized by required clamp force.
Are they Indian-made?
No. Carroland manufactures in China, with no Indian factory, office, or stock. Indian customers self-certify BIS using supplied IS 15867 reports.
Do they need a certificate to ship to India?
Carroland does not hold BIS; it supplies conforming parts and test reports so customers complete BIS self-certification where required.
