About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-20S
The AirTAC SAIJ200X60-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N at 0.5 MPa, within a specialized 40-60 mm usable travel window. This allows you to dial back the 60 mm nominal stroke by up to 20 mm during commissioning without swapping out the entire unit.
This specific SKU features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with CMSE reed and DMSE electronic sensors. Fluid ports are PT threaded, and the extruded aluminum barrel integrates sensor grooves on both sides for flexible switch mounting.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-20S Is Used
Heavy Press Tuning
Fine-tune the end position of a high-force pressing operation within the 40-60 mm window to accommodate material thickness variations without external stops.
Product Changeover
Quickly adjust the stroke by up to 20 mm on a packaging line when switching between different product sizes, minimizing machine downtime.
Short-Stroke Clamping
Utilize the 15708 N push force at 0.5 MPa for heavy-duty clamping tasks where precise positional limits must be set at commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-20S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires extreme force, such as 15708 N push at 0.5 MPa, over a short distance. If you need less thrust, stepping down to a 160 mm bore provides 10053 N push at 0.5 MPa. The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product size changeovers. To replace this cylinder per ISO 15552 mounting dimensions, match the 200 mm bore, 60 mm stroke, 20 mm adjustment, PT G3/4 port, and -S magnet.
Because the nominal stroke is 60 mm, external side-load guides are less critical than on longer strokes, though the robust 40 mm rod and M36x2 thread handle substantial loads. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ200X60-20-S cannot hold a load without live air. For pneumatic load-holding, consider an AirTAC SAIL or BSAI 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 SAIJ200AX60-20S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as a mechanical stop that allows you to trim the effective travel. For the SAIJ200X60-20-S, this creates a usable stroke window of 40-60 mm, letting you shorten the 60 mm nominal stroke by up to 20 mm.
