About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-20
The AirTAC SAIJ32X200-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 200 mm nominal stroke that can be dialed back by up to 20 mm, giving you a precise 180-200 mm usable travel window for product changeovers or fine end-position tuning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant is built with a SUS420J2 stainless steel rod for enhanced durability against moisture and minor side loading. It uses a PT tapered port thread, omits a piston magnet, and relies on adjustable air cushions at both ends to decelerate the load. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-20 Is Used
End-Position Tuning
Dial in the exact 180-200 mm retract distance during machine commissioning to perfect part seating without fabricating custom shims.
Product Changeover
Quickly shorten the effective stroke by up to 20 mm on a packaging line when switching to a slightly shorter product format.
Variable End Stops
Use the built-in rear stopper to create a precise mechanical limit for light-duty 402 N assembly tasks requiring flexible travel bounds.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-20 the Right Cylinder?
Choose this 32 mm bore model when your application requires 402 N of thrust at 0.5 MPa but demands on-the-fly stroke adjustments; if you need higher force, stepping up to the 40 mm bore yields 628 N. An adjustable stroke is selected over a fixed SAI cylinder when machine setups frequently change product sizes and require a variable end-stop rather than swapping the entire actuator. Because the stroke is 200 mm, an external guide is recommended to prevent excessive side-load wear on the rod.
To match this ISO 15552 interchangeable cylinder, specify a 32 mm bore, 200 mm stroke, 20 mm adjustment range, PT G1/8 port, and no magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. For load-holding without live air pressure, consider the SAIL or BSAI series instead, as this rear adjuster is not a lock.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32AX200-20 FAQ
The rear adjuster screw lets you shorten the 200 mm nominal stroke by up to 20 mm, creating a 180-200 mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
At a 0.5 MPa operating pressure, the SAIJ32X200-20 provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
