About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-100
The AirTAC SAIJ160X220-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 14074N push force at 0.7 MPa. With a nominal 220mm stroke and a 100mm adjustment range, the effective travel window can be dialed back anywhere from 120mm to 220mm during commissioning. This built-in stopper allows you to fine-tune the end position without swapping out the physical cylinder or adding external stops.
This specific SKU features a SUS304 stainless steel rod (code B) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-100 Is Used
Product Changeover Tuning
Quickly dial in the 120-220mm travel window during format changes on packaging lines without disassembling the actuator.
Variable End-Stop Positioning
Use the rear stopper to fine-tune the exact retraction point for heavy pressing or forming operations at 0.7 MPa.
Machine Setup Calibration
Set precise end-of-stroke limits during initial commissioning to prevent mechanical interference on large fixtures.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-100 the Right Cylinder?
Selecting this 160mm bore over a 125mm neighbor steps up the thrust significantly, moving from 8590N to 14074N push force at 0.7 MPa. The adjustable stroke is chosen when a machine requires variable end-stops or product-size changeovers, offering a 120-220mm usable travel window. Because the 220mm stroke exceeds 300mm, no external side-load guide is strictly required here, but the substantial 40mm rod and M36x2 thread handle high side loads well.
When matching this for an ISO 15552 replacement, verify the 160mm bore, 220mm stroke, 100mm adjustment range, PT port threads, and the SUS304 stainless rod material. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments. Remember that the rear adjuster only decelerates and sets the travel end; it is not a lock.
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 SAIJ160BX220-100 FAQ
The rear adjuster allows you to shorten the effective stroke by up to 100mm, providing a usable travel window of 120mm to 220mm. It acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
At 0.7 MPa operating pressure, it provides a push force of 14074N and a pull force of 9425N. It can reach a maximum push force of 18095N at 0.9 MPa.
