About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-30
The AirTAC SAIJ63X800-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 800 mm stroke that can be fine-tuned backward by up to 30 mm, creating a precise 770-800 mm usable travel window. Operating at 0.5 MPa, it delivers 1559 N of pull force and 2182 N at 0.7 MPa, making it a robust choice for medium-to-heavy pneumatic tasks.
This model uses a carbon steel piston rod with an M16x1.5 thread, paired with a G3/8 port for optimal airflow. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the direct mounting of CMSE reed or DMSE electronic sensors if a magnet is specified later. It relies on adjustable air cushions at both ends to decelerate the load smoothly over the long travel distance.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-30 Is Used
Long-Reach Transfer
Pushes products across wide conveyor gaps, using the 30 mm rear adjustment to dial in the exact 770-800 mm end position without adding external stops.
Machine Changeover
Quickly adapts the retract end-stop for different product sizes on a packaging line, fine-tuning the travel window during commissioning rather than changing hardware.
Material Handling
Moves moderate payloads along an 800 mm stroke, relying on the 36 mm air cushions to safely decelerate the carbon steel rod at the end of travel.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X800-30 the Right Cylinder?
Select this 63 mm bore cylinder when an application requires a lengthy 800 mm reach but demands exact end-position tuning during commissioning or product changeover, avoiding the need to swap out the entire cylinder or bolt on external stopper blocks. If your setup requires less force, stepping down to a 50 mm bore yields 825 N of pull force at 0.5 MPa; conversely, an 80 mm bore provides 2268 N for heavier loads. Because the stroke is 800 mm, an external guide is highly recommended to prevent excessive side-loading on the rod.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 800 mm stroke, 30 mm adjustment range, PT tapered port thread, and mounting choice from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster and air cushions act strictly as travel stops and deceleration devices; they do not hold the load without live air pressure. For dead-load holding, consider an AirTAC SAIL or BSAI variant.
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 SAIJ63X800-30 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of pull force and 1402 N of push force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 800 mm down to 770 mm. This creates a 770-800 mm usable window for fine-tuning the end position at commissioning, but it acts only as a stop and does not lock the load without air pressure.
