About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X210-100
The AirTAC SAIJ63X210-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 1559N of pull force at 0.5MPa. It features a carbon steel piston rod with an M16x1.5 thread and a G3/8 port. By turning the rear stopper screw, you can trim the forward travel anywhere within a 110-210mm usable window, making it ideal for product size changeovers without swapping hardware.
This adjustable-stroke unit uses standard PT tapered port threads and operates at speeds of 30-800mm/s. It retains the standard ISO 15552 mounting footprint and includes adjustable air cushions at both ends to decelerate the load smoothly. For position feedback, adding a magnet allows the use of AirTAC CMSE reed or DMSE electronic sensors in the dual-side barrel grooves.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X210-100 Is Used
Product Size Changeovers
Quickly reconfigure the end-of-stroke position on packaging lines handling varying carton lengths, utilizing the 110-210mm travel window without replacing the cylinder.
Machine Setup Commissioning
Fine-tune the final extended position during initial machine build to perfectly dial in tooling alignment, avoiding the need to add external mechanical shims.
Variable End-Stop Positioning
Provide a flexible physical stop for assembly presses that need to adapt downstream pusher distances based on the specific component being loaded.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X210-100 the Right Cylinder?
Choose this 63mm bore when an application requires approximately 1559N of pull force at 0.5MPa, stepping up from a 50mm bore (982N pull) or down from an 80mm bore (2268N pull). The generous 100mm adjustment window is perfect for machines running multiple product sizes, allowing operators to dial in the exact end position during commissioning rather than machining external stops or buying a fixed-stroke SAI cylinder. Remember that the rear adjuster is a travel stop, not a lock; the cylinder will not hold a load without live air, so consider an AirTAC SAIL or BSAI model if true load-holding is required.
When replacing an ISO 15552 cylinder, verify the 63mm bore, 210mm nominal stroke, 100mm adjustment range, G3/8 PT port, and your preferred mounting style from the available SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because the nominal stroke is 210mm, ensure your mounting configuration adequately supports the rod to prevent excessive side-loading, relying on external guides if necessary.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X210-100 FAQ
At 0.5MPa operating pressure, this 63mm bore cylinder provides 1559N of pull force and 2182N of push force. At 0.7MPa, the push force increases to 2805N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from its 210mm nominal length down to 110mm. This creates a 110-210mm usable travel window for fine-tuning end positions without changing the cylinder.
