About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-30S
The AirTAC SAIJ200X270-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 240-270 mm from its 270 mm nominal stroke. Delivering 15708 N of push force at 0.5 MPa, this large-bore actuator handles heavy-duty positioning. It includes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread.
The integrated rear stopper allows precise end-position tuning during commissioning without swapping out the physical cylinder. The extruded aluminum barrel features sensor grooves on both sides, and because this unit includes a magnet (-S), it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-30S Is Used
Heavy Press Tuning
Dial in the exact 240-270 mm end-stop during machine setup to accommodate varying material thicknesses without changing the actuator.
Product Changeover
Rapidly adjust the retract distance on automated assembly lines when switching between different product sizes and formats.
High-Force Testing
Leverage the 15708 N push force and SUS304 rod for robust, corrosion-resistant actuation in heavy industrial test fixtures.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-30S the Right Cylinder?
Choose this 200 mm bore when your application requires substantial thrust—stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The adjustable rear screw is ideal for fine-tuning the retract end-position on product changeovers, avoiding the need to bolt on external stops or buy a different fixed-stroke SAI cylinder. For an exact ISO 15552 replacement match, specify the 200 mm bore, 270 mm stroke, 30 mm adjustment, PT ports, and the -S magnet option.
Because the nominal stroke is 270 mm, maintaining reliable operation requires an external guide to prevent excessive side-loading on the 40 mm rod. Remember that the rear adjuster functions strictly as a travel stop to decelerate the load, not as a locking device; the cylinder cannot hold its position without live air pressure. For true fail-safe load holding, consider an AirTAC SAIL or BSAI series cylinder.
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 SAIJ200 Adjustable Cylinder SAIJ200BX270-30S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 30 mm, providing a usable travel window between 240 and 270 mm. It only sets the travel end and does not lock the load without live air pressure.
