About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-10
The AirTAC SAIJ32X140-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 130-140 mm usable travel window, allowing you to dial back the nominal 140 mm stroke by up to 10 mm 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 variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic sensors if a magnet is added later. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-10 Is Used
Machine Changeover
Dial in the 130-140 mm travel window during product size changes without physically replacing the cylinder or bolting on external stop blocks.
End-Position Tuning
Fine-tune the retract end position at commissioning to compensate for mechanical tolerance stack-up in the fixture.
Light-Duty Positioning
Position light parts using the 402 N push force at 0.5 MPa, relying on external guides for side-load stability.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-10 the Right Cylinder?
Choose this 32 mm bore adjustable model when you need precise end-position tuning without swapping cylinders or adding external stops. If your application requires higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, this cylinder will not hold a load without live air—consider SAIL or BSAI variants for fail-safe load holding.
For an exact ISO 15552 replacement match, verify the 32 mm bore, 140 mm nominal stroke, 10 mm adjustment range, PT G1/8 port, and SUS304 (B) rod material. The standard speed range is 30-800 mm/s.
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 SAIJ32BX140-10 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 0.7 MPa, the push force increases to 563 N.
A rear adjuster screw lets you shorten the effective travel from the nominal 140 mm down to 130 mm. This creates a 130-140 mm usable window for fine-tuning the retract end position without changing the cylinder's physical mounting.
