About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-50
The AirTAC SAIJ100X220-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 170 to 220 mm. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers a robust 5497 N push force at 0.7 MPa. This adjustable-stroke design allows you to fine-tune the retract end position during commissioning without swapping the cylinder or adding external stops.
The rear adjuster acts as a mechanical stop to set the travel end, not a lock, meaning it cannot hold a load without live air. For load-holding without pressure, consider the SAIL or BSAI series. This model supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-50 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 170 and 220 mm during machine setup, allowing for rapid product-size changeovers without replacing the entire cylinder.
Commissioning Fine-Tuning
Use the rear adjusting screw to trim the stroke by up to 50 mm, compensating for mechanical tolerance buildup without the need to bolt on external stops.
Heavy-Duty Forming Press
Leverage the 5497 N push force at 0.7 MPa for robust clamping or forming operations, while maintaining the flexibility to adjust the end position on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-50 the Right Cylinder?
Select this 100 mm bore when an application requires substantial thrust, such as the 5497 N push force at 0.7 MPa, but still needs precise end-position tuning. If your force requirements are lower, stepping down to an 80 mm bore yields 3518 N, whereas moving up to a 125 mm bore provides 8590 N. The adjustable stroke is ideal for product-size changeovers on a line, letting you dial in the exact 170-220 mm travel window on the fly instead of machining custom spacers.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 220 mm nominal stroke, 50 mm adjustment range, PT G1/2 port thread, and the appropriate mounting bracket. Because the total travel exceeds 300 mm, ensure you use an external guide to prevent excessive side-loading on the SUS304 rod, as the adjuster only sets the travel end and does not bear lateral loads.

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100BX220-50 FAQ
The rear adjuster allows you to shorten the effective stroke by up to 50 mm, creating a usable travel window of 170 to 220 mm. It acts as a mechanical stop to set the end position, but it is not a lock and requires live air to hold the load.
At an operating pressure of 0.7 MPa, the SAIJ100X220-50 provides a push force of 5497 N and a pull force of 3681 N. The maximum push force is 7068 N at 0.9 MPa.
