About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-40S
The AirTAC SAIJ200X650-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 15708N of push force at 0.5 MPa. Its 650mm nominal stroke incorporates a 40mm adjustment range, yielding a precise 610-650mm usable travel window. This allows operators to dial in the exact end position during commissioning without adding external stops.
Built with a SUS420J2 stainless steel rod and a -S magnet for CMSE or DMSE sensors, this unit handles high side loads. The rear screw acts purely as a travel stop for deceleration alongside the standard air cushions, meaning it cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-40S Is Used
Heavy Press Tuning
Fine-tune the 610-650mm end position during setup to precisely crush or form heavy materials without recalculating fixed mechanical stops.
Product Changeovers
Adjust the stroke on the fly when switching between large pallet sizes on a conveyor line, using the 40mm rear stopper to adapt the travel window.
Automated Assembly
Leverage the 15708N push force to seat massive components, using the adjustable end-stop to accommodate varying part heights.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-40S the Right Cylinder?
Select this 200mm bore cylinder when an application demands extreme thrust, stepping up from a 160mm bore that provides 10053N at 0.5 MPa. The adjustable 610-650mm window is perfect for product-size changeovers on a line, avoiding the need to physically swap out a fixed-stroke SAI cylinder. Because the stroke is 650mm, an external guide is strongly recommended to manage side loads on the long unsupported rod.
For an exact ISO 15552 replacement match, verify the 200mm bore, 650mm stroke, 40mm adjustment, PT tapered port threads, and the -S magnet. If true load-holding is required without live air, a plain SAIJ will not suffice; you must integrate an external rod lock or look at the SAIL or BSAI locking cylinder variants.
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 SAIJ200AX650-40S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 0.9 MPa.
The rear adjuster allows you to trim the effective travel by up to 40mm from the 650mm nominal stroke, creating a 610-650mm usable window. This stopper only sets the travel end and does not lock the load without continuous air pressure.
