About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-10
The AirTAC SAIJ200X270-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 270 mm stroke with an adjustable travel window of 260 to 270 mm, allowing precise end-position tuning without adding external stops. The 200 mm bore generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suited for heavy-duty positioning tasks.
This variant incorporates an SUS420J2 stainless steel rod for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and operates at speeds between 30 and 500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-10 Is Used
Variable End-Stop Tuning
Dial in the exact retract position within a 260-270 mm window during machine commissioning to accommodate varying product dimensions without swapping cylinders.
Heavy-Duty Pressing
Leverage 15708 N of push force at 0.5 MPa for heavy assembly operations, using the rear screw to fine-tune the final pressing depth precisely.
Line Changeover Setup
Adjust the 10 mm stroke range quickly on automated lines during product size transitions, relying on the SUS420J2 rod for durability in diverse environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-10 the Right Cylinder?
Select this 200 mm bore model when an application demands substantial thrust, such as 15708 N at 0.5 MPa, alongside a finely tunable 260-270 mm stroke. If a shorter fixed stroke is acceptable, the standard SAI series avoids the adjuster mechanism, but the SAIJ rear screw is invaluable for product changeovers where exact end positions vary by a few millimeters. For a smaller footprint, a 160 mm bore yields 10053 N of push force at 0.5 MPa.
Because this cylinder features a 270 mm stroke, an external guide is recommended to manage side loads on the 40 mm rod over extended travel. The rear stopper and integrated air cushions decelerate the piston but cannot maintain position without continuous air pressure; for true load-holding, consider the SAIL or BSAI series. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ200AX270-10 FAQ
At a 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 allows you to shorten the effective stroke from the nominal 270 mm down to 260 mm. This provides a 10 mm tuning window for precise end-positioning at commissioning without external stops.
