About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-10
The AirTAC SAIJ32X180-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 180 mm travel by up to 10 mm. This creates a precise 170-180 mm usable window, enabling exact end-position tuning at commissioning without swapping out the physical unit. As the smallest bore in the series, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
Built with a SUS304 stainless steel rod (option B), this variant is well-suited for environments where corrosion resistance is prioritized. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches, though this specific SKU is not equipped with a standard magnet. It features PT tapered port threads (G1/8) and uses a 12 mm rod with an M10x1.25 thread, which handles side loads adequately for its compact size, though long unsupported strokes still require an external guide.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-10 Is Used
Machine Changeover
Dial in the 170-180 mm stroke window precisely when switching product sizes on a packaging line, avoiding the need to physically swap cylinders or reposition hard stops.
Light Assembly
Provides 402 N of push force at 0.5 MPa for driving small presses or locating fixtures, with the rear screw allowing micro-adjustments to perfect the final end position.
Lab Automation
The SUS304 stainless steel rod offers excellent corrosion resistance for cleanroom or laboratory environments where minor stroke adjustments are frequently needed.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-10 the Right Cylinder?
Choose this 32 mm bore when your application requires light thrust up to 402 N at 0.5 MPa. If your setup demands more force, stepping up to the 40 mm bore increases push thrust to 628 N, while dropping to a smaller bore is not available within this ISO 15552 standard range. The 10 mm adjustment range is ideal for fine-tuning a 180 mm stroke during machine changeovers or compensating for mechanical tolerance stack-up without adding external stops.
Because the rear adjuster functions strictly as a travel stop and the air cushions manage end-of-stroke deceleration, neither feature will hold a load safely without live air pressure. If your process requires true load-holding in the event of pressure loss, consider the AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) series instead. This SAIJ model is dimensionally interchangeable with ISO 15552 cylinders, utilizing a mounting interface subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32BX180-10 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as an external stopper, allowing you to shorten the effective stroke from 180 mm down to a minimum of 170 mm. This provides a 170-180 mm usable travel window for fine-tuning the end position during setup without replacing the cylinder.
