About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-100
The AirTAC SAIJ32X550-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 450 to 550 mm. Delivering 402 N of push force at 0.5 MPa, it utilizes a 12 mm SUS304 stainless steel rod and features a PT tapered G1/8 port. The extruded aluminum barrel includes sensor grooves on both sides for straightforward positioning feedback.
This model allows operators to fine-tune the retract end-position during commissioning or product changeovers without swapping out the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and relies on the variable air cushion for end-of-stroke deceleration; it does not hold the load without live air pressure. For load-holding requirements without continuous air, a SAIL or BSAI series cylinder is recommended.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-100 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 450 and 550 mm during machine setup to handle varying material lengths without changing hardware.
Product Size Changeovers
Quickly adjust the stroke end-point on packaging or conveying lines to accommodate different carton or product dimensions on the fly.
Commissioning Fine-Tuning
Trim the nominal 550 mm stroke by up to 100 mm to perfectly time machine sequencing and avoid mechanical hard stops during initial integration.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-100 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa, but demands on-the-fly end-position tuning across a 450-550 mm window. If your process needs higher thrust, stepping up to the 40 mm bore yields 628 N at the same pressure. The 12 mm SUS304 rod provides excellent corrosion resistance and handles moderate side loads, though at 550 mm of travel, an external guide is strongly advised to prevent rod binding.
The adjustable rear stopper is ideal for accommodating multiple product sizes on a single line without mechanical rebuilds. This configuration features PT tapered ports, omits the magnet for sensors, and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. It is dimensionally interchangeable per ISO 15552 without relying on tie-rod construction.

- ✓ 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 SAIJ32BX550-100 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 550 mm down to 450 mm. This creates a 450-550 mm adjustable window for fine-tuning end positions at commissioning without replacing the cylinder.
