About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-30
The AirTAC SAIJ32X220-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm. This yields a usable stroke window of 190 to 220 mm, enabling precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers 402 N of push force at 0.5 MPa and uses a SUS420J2 stainless steel rod for enhanced corrosion resistance.
The rear adjuster acts purely as a travel stop to set the retract end position and relies on the integrated air cushions for deceleration; it does not hold the load without live air pressure. For position holding without continuous air, consider the SAIL or BSAI series. This 32 mm bore model features a PT G1/8 tapered port, an M10x1.25 rod thread, and operates at speeds from 30 to 800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-30 Is Used
Machine Changeover
Dial in the exact 190-220 mm travel needed for different product sizes on a packaging line without replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke during commissioning to perfect sensor alignment and seating positions, using the rear screw rather than repositioning the whole assembly.
Variable End Stops
Adjust the travel end point dynamically on testing fixtures to accommodate varying part dimensions, leveraging the 30 mm adjustment range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-30 the Right Cylinder?
Choose this adjustable-stroke cylinder when your machine setup requires variable end stops or frequent product changeovers, as the 30 mm adjustment window allows fine-tuning without mechanical modifications. If your application requires greater thrust, stepping up to the 40 mm bore provides 628 N of push force at 0.5 MPa. Conversely, if you need a fixed travel without adjustment, the standard SAI series is a simpler alternative.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 32 mm bore, 220 mm stroke, up to 30 mm rear adjustment, PT G1/8 port thread, SUS420J2 stainless steel rod, and no magnet. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the 220 mm stroke is within standard limits, side-load concerns are minimal, but an external guide is recommended for heavy lateral loads.

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 Adjustable Cylinder SAIJ32 SAIJ32AX220-30 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. At the maximum pressure of 1.0 MPa, it achieves up to 82 kgf of push force.
The rear adjuster screw allows you to shorten the nominal 220 mm stroke by up to 30 mm, creating a usable travel window of 190 to 220 mm. The adjuster acts as a mechanical stop for the retract end and does not function as a lock or brake to hold the load without live air pressure.
