About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX85-10S
The AirTAC SAIJ200X85-10-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. A built-in rear stopper screw provides a 10 mm adjustment range, allowing you to dial in the effective travel window from 75 to 85 mm during commissioning. This fine-tuning capability eliminates the need to bolt on external physical stops or swap out the entire actuator when refining your machine's end positions.
Delivering 15708 N of push force and 15080 N of pull force at 0.5 MPa, this 200 mm bore actuator handles substantial loads. The piston rod is machined from SUS420J2 stainless steel, and the unit includes a magnetic piston (-S) for direct compatibility with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel features sensor grooves on both sides, and the mounting footprint supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX85-10S Is Used
Heavy Press Positioning
Dial in the exact 75-85 mm travel window for a 15708 N pressing operation, ensuring precise material deformation without adding external stoppers.
Machine Changeover
Quickly adjust the rear stopper screw during product family transitions to accommodate slightly different package sizes on the same heavy-duty line.
Large Assembly End-Stop
Use the 10 mm trim range to fine-tune the retraction end position of a 200 mm bore assembly actuator, compensating for mechanical wear over time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX85-10S the Right Cylinder?
Choose this 200 mm bore model when your application demands maximum thrust, stepping up from a 160 mm bore cylinder that provides 10053 N of push force at 0.5 MPa. The adjustable rear stopper is ideal for product changeovers or fine-tuning a machine setup, offering variable end stops without the rigidity of a fixed-stroke SAI cylinder. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, select an SAIL air-released lock or BSAI clamp-lock cylinder.
This SAIJ configuration features PT tapered port threads and operates at speeds between 30 and 500 mm/s. Because the 85 mm stroke is relatively short, side-load stress on the M36x2 rod thread is minimal, though an external guide is always recommended for heavy lateral loads. The unit is dimensionally interchangeable per ISO 15552 mounting-interface dimensions.
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 SAIJ200AX85-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It can deliver up to 21991 N of push force at 0.7 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 85 mm nominal stroke by up to 10 mm, providing a usable travel window of 75 to 85 mm. This stopper only sets the travel end and does not lock or hold the load without continuous air pressure.
