About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX275-75
The AirTAC SAIJ200X275-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 275 mm nominal stroke by up to 75 mm. This creates a usable travel window of 200-275 mm, providing fine end-position tuning during commissioning or product changeovers without swapping the hardware. Delivering a robust 21991 N push force at 0.7 MPa, it handles heavy industrial loads with precision.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors, though this particular SKU does not include a magnet. The rear adjuster acts strictly as a travel stop to set deceleration, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX275-75 Is Used
Heavy Press Tonnage Setup
Fine-tune the exact end-of-stroke pressing position on heavy machinery during initial commissioning, using the 75 mm adjustment window to set precise tonnage without machining new spacers.
Variable Product Size Forming
Accommodate different material blank lengths on a single forming line by dialing the travel back from 275 mm to 200 mm, enabling rapid changeover between product sizes.
Robotic End Effector Calibration
Provide a mechanically adjustable stroke stop for heavy-payload robotic grippers, ensuring the SUS304 rod reaches the exact programmed retraction point during automated cell integration.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX275-75 the Right Cylinder?
Choose this 200 mm bore cylinder when your application demands high thrust—up to 21991 N at 0.7 MPa—combined with variable end-stop positioning. The adjustable stroke is ideal for machine setup and product-size changes, offering flexibility that a fixed-stroke SAI cannot match. If your force requirements are lower, stepping down to a 160 mm bore yields 14074 N at 0.7 MPa, while moving up is not possible within this series. Because the 275 mm stroke is relatively short for this massive bore, side-loading risks are minimized, but an external guide is still recommended for heavy off-center loads.
For an exact ISO 15552 replacement, match the 200 mm bore, 275 mm stroke, 75 mm adjustment, PT port thread, and SUS304 rod material. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets. For true load-holding without live air, consider the SAIL or BSAI series, as this cylinder's adjuster is not a locking mechanism.

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 SAIJ200BX275-75 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm, providing a usable travel range of 200-275 mm. It acts as a mechanical stop that sets the deceleration point but does not lock or hold the load without continuous air pressure.
At a 0.7 MPa operating pressure, the SAIJ200X275-75 generates 21991 N of push force and 15080 N of pull force. It can reach a maximum push force of 28274 N at 0.9 MPa.
