About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX850-75S
The AirTAC SAIJ200X850-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, providing 15708 N of push force and 15080 N of pull force at 0.5 MPa. The built-in -75 mm adjustment mechanism creates a usable travel window of 775 to 850 mm, allowing you to dial in the exact retract end-position without swapping out the entire unit.
This heavy-duty actuator features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and carries PT tapered port threads sized at G3/4. Because it includes the -S magnet option, it directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side extruded aluminum barrel grooves. The rear adjuster functions strictly as a travel stop to fine-tune deceleration, not as a load lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX850-75S Is Used
Heavy Press Tuning
Fine-tune the 775-850 mm retract position on large stamping or press equipment during setup, ensuring perfect contact without machining external stopper blocks.
Pallet Changeover
Adapt a high-thrust diverter on a packaging line to accommodate different pallet sizes by simply turning the rear adjuster screw rather than replacing the actuator.
Large Assembly Jigs
Provide adjustable end-stops for massive industrial assembly jigs, leveraging the 15708 N push force to move heavy structural components into their final alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX850-75S the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when an application demands extreme force alongside variable end-stop positioning during product changeovers. If 15708 N at 0.5 MPa exceeds your requirements, stepping down to a 160 mm bore yields 10053 N of push force while maintaining a similar ISO 15552 footprint. To replace an ISO 15552 cylinder, match the 200 mm bore, 850 mm stroke, -75 adjustment, G3/4 PT ports, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.
Because this cylinder features an 850 mm stroke, the 40 mm diameter rod and M36x2 rod thread will still experience leverage forces under heavy side-loading; an external guide mechanism is strongly recommended to prevent premature seal wear. For applications requiring the load to be held in place without continuous live air pressure, a plain SAIJ cylinder is insufficient since the rear stopper and air cushions are not brakes. You should instead specify an AirTAC SAIL pneumatic lock cylinder, a BSAI clamp-lock model, or an external pilot-operated check valve.
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 SAIJ200AX850-75S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 21991 N at 0.7 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective travel. For this 850 mm stroke model, the -75 adjustment code allows you to trim the retract stroke back by up to 75 mm, creating a usable travel window of 775 to 850 mm.
