About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-50
The AirTAC SAIJ160X220-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 10053N pull force at 0.5MPa and uses a SUS304 stainless steel rod for superior corrosion resistance. The PT tapered ports ensure a tight, reliable pneumatic seal.
This model provides a usable travel window of 170-220mm, letting you dial back the nominal 220mm stroke by up to 50mm. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-50 Is Used
End-Position Tuning
Dial in the exact retract distance during machine commissioning to perfect a pressing or forming motion without swapping hardware.
Product Changeover
Quickly adapt the cylinder's effective travel window when a production line switches to a different sized component.
Variable Stops
Set precise mechanical end-stops for heavy-duty material handling tasks that require strict positional boundaries.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-50 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your setup requires commissioning fine-tune or variable end-stops without adding external stops. If you need less force, stepping down to a 125mm bore yields 5734N pull at 0.5MPa. Since the 220mm stroke is under 300mm, side-load risks are moderate, but an external guide is still recommended for heavy lateral loads.
This SKU is dimensionally interchangeable per ISO 15552. Configuration: 160mm bore, 220mm stroke, 50mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, no magnet. It operates at 30-500mm/s. For position holding without live pressure, use an external rod 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 SAIJ160BX220-50 FAQ
At 0.5MPa, it provides 14074N push force and 10053N pull force. At 0.7MPa, the push force increases to 14074N.
The rear adjuster allows you to shorten the effective stroke from 220mm down to 170mm, giving a 170-220mm travel window for fine-tuning without replacing the cylinder.
