About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-10S
The AirTAC SAIJ32X550-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 540-550mm usable travel window, letting you dial back the nominal 550mm stroke by up to 10mm during machine commissioning without adding external stops. It delivers 402N of push force at 0.5MPa and uses a PT tapered G1/8 port.
This specific SKU includes a SUS304 stainless steel rod for superior corrosion resistance and comes pre-fitted with a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. While the rear adjuster fine-tunes the retract position, remember it acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-10S Is Used
Machine Commissioning
Fine-tune the 540-550mm retract end-stop precisely during setup, absorbing mechanical tolerance variations without hardware changes.
Product Changeover
Quickly adjust the stroke by up to 10mm to accommodate slightly different product sizes on a packaging line.
Gripping & Pushing
Utilize the 12mm SUS304 stainless steel rod for light-duty pushing tasks in environments where corrosion resistance is required.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-10S the Right Cylinder?
Choose this 32mm bore cylinder when your application requires 402N of push force at 0.5MPa but demands exact end-position tuning. The 10mm adjustment window is ideal for product changeovers on a line, preventing the need to physically swap cylinders for minor length differences. If you need higher force, stepping up to a 40mm bore yields 628N, whereas dropping to a smaller bore would reduce your thrust significantly.
For any stroke length of 550mm, side-load management is critical. The 12mm rod and M10x1.25 thread handle moderate loads, but you must use an external guide to prevent rod binding over this extended travel. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. If your application requires true load-holding without continuous air supply, consider the SAIL or BSAI series instead.
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 SAIJ32BX550-10S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 10mm, providing a 540-550mm travel window. It only sets the end position; it does not lock or hold the load without live air pressure.
At 0.5MPa, it provides 402N of push force and 345N of pull force. The operating speed range is 30-800mm/s, and it features variable air cushions at both ends to decelerate the piston.
