About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-50
The AirTAC SAIJ32X800-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 800 mm stroke that can be dialed back by up to 50 mm, creating a precise 750-800 mm usable travel window for fine-tuning end positions during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This model uses a SUS420J2 stainless steel rod for enhanced durability against side loads, paired with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. 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 SAIJ32AX800-50 Is Used
Machine Setup Tuning
Dial in the exact 750-800 mm retract end-position during initial machine commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adjust the stroke stop by up to 50 mm to accommodate varying package lengths on a packaging line.
Variable End Stops
Fine-tune the final position of a long-travel actuator to align perfectly with downstream equipment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-50 the Right Cylinder?
Choose this adjustable-stroke model when a fixed 800 mm SAI cylinder cannot accommodate minor mechanical variations or product changeovers, allowing you to dial in the exact 750-800 mm end-stop without adding external shims. If your application requires higher force, stepping up to a 40 mm bore provides 628 N of push force at 0.5 MPa. Because the total stroke is 800 mm, the unsupported rod length is significant; an external guide is highly recommended to prevent excessive side-loading and premature seal wear.
For ISO 15552 replacement matching, verify a 32 mm bore, 800 mm stroke, 50 mm adjustment range, PT port thread, and the required mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the SAIJ series omits FB, CA, CB, and CR mounts. The rear adjuster and variable air cushions only decelerate the load; for true load-holding without live air, select an SAIL or BSAI cylinder.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAIJ32AX800-50 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum pressure of 1.0 MPa, it can deliver up to 82 kgf.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective travel from the nominal 800 mm down to 750 mm. It sets the end position but does not lock or hold the load without continuous air pressure.
