About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-20
The AirTAC SAIJ200X270-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. It features a robust 40 mm SUS304 stainless steel rod and generates 15708 N of push force at 0.5 MPa, scaling up to 21991 N at 0.7 MPa. A rear adjusting screw allows you to fine-tune the effective travel, providing a usable stroke window of 250 to 270 mm without adding external stops.
This model uses PT tapered port threads and includes adjustable air cushions at both ends to manage kinetic energy. The extruded aluminum barrel integrates sensor grooves on both sides, supporting precise position feedback. Because the rear adjuster functions purely as a travel stop to set the retraction point, it does not hold the load dynamically without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-20 Is Used
Heavy Pressing Operations
Delivers up to 21991 N of push force at 0.7 MPa for forming and pressing tasks, with the 20 mm rear adjuster allowing exact tuning of the final compaction distance.
Product Changeover Lines
The 250-270 mm adjustable travel window lets operators quickly reposition the end-stop for different product heights without physically swapping out the cylinder.
Large Assembly Jigs
Features a 40 mm SUS304 stainless steel rod for high rigidity and corrosion resistance in demanding industrial environments, handling heavy payloads securely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-20 the Right Cylinder?
Select this 200 mm bore cylinder when your application demands substantial thrust, such as 15708 N push or 15080 N pull at 0.5 MPa, alongside a 250-270 mm adjustable travel window. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N push force, whereas moving up is unnecessary unless exceeding 3204 kgf at 1.0 MPa. Choose this adjustable-stroke SAIJ variant over a fixed SAI when you need on-machine commissioning flexibility for variable product sizes or exact end-stop tuning.
To match this ISO 15552 interchangeable replacement, confirm the 200 mm bore, 270 mm nominal stroke, 20 mm adjustment range, PT port threads, and the SUS304 (B) rod material. Note that no magnet is specified for this configuration, so CMSE or DMSE sensors cannot be used without adding the -S option. For a 270 mm stroke, the 40 mm rod provides excellent rigidity, though long unsupported loads still require an external guide to prevent side-loading damage.

- ✓ 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 SAIJ200 Adjustable Cylinder SAIJ200BX270-20 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw acts as a mechanical stop that trims the retract travel. For this 270 mm nominal stroke cylinder, you can dial back the effective stroke by up to 20 mm, creating a usable travel window of 250 to 270 mm.
