About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX30-10
The AirTAC SAIJ32X30-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down from 30 mm to a 20 mm minimum, creating a 20-30 mm usable window. This fine-tuning capability is ideal for dialing in end positions during machine commissioning without swapping out the actuator. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and uses a PT tapered port.
The rear adjuster functions purely as a mechanical stop to set the retract end position, meaning it cannot hold a load without live air pressure. For load-holding requirements, a SAIL or BSAI series cylinder is required. This extruded aluminum profile barrel includes sensor grooves on both sides for CMSE or DMSE switches, and supports a mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX30-10 Is Used
Machine Commissioning
Dial in the exact retract end-position within the 20-30 mm window during initial equipment setup without adding external stops.
Product Changeover
Quickly adjust the stroke by up to 10 mm to accommodate slight variations in product size on a shared production line.
End-Stop Tuning
Fine-tune the travel limit on low-thrust tasks to prevent mechanical crashing, relying on the 402 N push force at 0.5 MPa.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX30-10 the Right Cylinder?
Choose this 32 mm bore if your application requires around 402 N of push force at 0.5 MPa, or step down if you need less thrust. The 12 mm rod and M10x1.25 thread provide adequate support for short 30 mm strokes, though longer unsupported strokes would need an external guide. An adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers or precise end-position tuning at setup. Because the stroke is under 300 mm, side-load risks are minimal, but always ensure the load is guided to prevent rod binding. To replace an ISO 15552 cylinder, match the 32 mm bore, 30 mm stroke, 10 mm adjustment, PT port, and your required mounting style.

- ✓ 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 SAIJ32BX30-10 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 push force reaches 724 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 30 mm nominal stroke by up to 10 mm. This creates a usable travel window of 20-30 mm for precise end-position tuning.
