About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-10S
The AirTAC SAIJ80X170-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5MPa, utilizing a 25mm carbon steel rod and a PT tapered port. By integrating a 10mm adjustment screw, this model creates a precise 160-170mm usable travel window, enabling exact end-position tuning during commissioning without swapping out the entire unit.
This extruded aluminum profile cylinder includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The rear stopper acts purely as a travel limit and works alongside standard variable air cushions at both ends. It is important to note that this adjuster is not a locking mechanism, so external load-holding devices are required if pneumatic pressure is removed.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-10S Is Used
Precision End-Stop Tuning
Dial in the exact 160-170mm retraction point during machine commissioning to perfect component seating without adding external physical stops.
Product Changeover
Quickly adjust the stroke by up to 10mm on the fly to accommodate slight variations in product sizes running through the same line.
Heavy Payload Shifting
Leverage the 2513N push force at 0.5MPa to move heavier fixtures while fine-tuning the end position to prevent hard mechanical crashes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-10S the Right Cylinder?
Selecting this 80mm bore over a smaller 63mm option steps the thrust up significantly from 1559N to 2513N at 0.5MPa, making it suitable for heavier actuation tasks. The 10mm adjustable range is ideal for applications requiring slight positional corrections during machine setup or product changeovers, avoiding the rigid limitations of a fixed-stroke SAI cylinder. To match this ISO 15552 footprint exactly, specify the 80mm bore, 170mm stroke, 10mm adjustment, PT port, and the -S magnet option.
Because the 170mm stroke is relatively compact for this bore size, side-load stress on the 25mm rod is minimized compared to longer extensions. However, any unsupported loads should still utilize external guiding. If true position holding without live air pressure is needed, consider the SAIL or BSAI locking cylinder variants instead of relying on the adjustment stopper.
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 SAIJ80 Adjustable Cylinder SAIJ80X170-10S FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can reach up to 4523N push force at 0.9MPa.
The rear adjuster screw allows you to shorten the nominal 170mm stroke by up to 10mm, creating a 160-170mm travel window. This stopper only limits the travel end and does not lock the load.
