About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-10
The AirTAC SAIJ160X270-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 260-270 mm usable travel window, allowing you to trim the effective stroke by up to 10 mm during commissioning without swapping the cylinder. Built with a robust 160 mm bore, it delivers a substantial 18095 N of push force at 0.9 MPa.
This heavy-duty actuator features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, the design supports AirTAC CMSE reed and DMSE electronic sensors when needed.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-10 Is Used
Heavy Press Tuning
Dial in the exact bottoming position of a high-force press during initial commissioning, using the 10 mm adjustment window to perfect the crush distance without external shims.
Product Changeover
Quickly adapt the retract end-stop on an automated line when switching to a slightly different product variant, saving time on physical machinery modifications.
Material Forming
Provide precise end-position control for heavy material forming operations, relying on the 18095 N push force to shape components reliably.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-10 the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires high thrust, such as 14074 N push at 0.7 MPa, but still needs micro-adjustments to the end position. If your setup demands less force, stepping down to a 125 mm bore yields 11045 N at 0.9 MPa. Conversely, moving up to a 200 mm bore provides 28274 N at 0.9 MPa. The adjustable rear stopper is ideal for fine-tuning machine setups, whereas a fixed SAI cylinder locks you into a single exact dimension.
Because the nominal stroke is 270 mm, ensure proper external guiding to prevent excessive side-loading on the rod. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. This model uses a PT tapered port thread and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160 Adjustable Cylinder SAIJ160BX270-10 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. At 0.5 MPa, the push force is 10053 N.
The rear adjuster screw allows you to shorten the 270 mm nominal stroke by up to 10 mm, creating a 260-270 mm usable travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
