About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-10
The AirTAC SAIJ32X135-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 125 to 135 mm. Delivering 402 Newtons of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and features a PT tapered G1/8 port.
This adjustable-stroke model allows you to fine-tune the retract end position at commissioning without adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for position holding, consider the SAIL or BSAI series. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-10 Is Used
End-Position Tuning
Dial in the exact 125 to 135 mm retract distance during machine commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adjust the stroke stop on a packaging line to accommodate slight variations in incoming product sizes.
Light Assembly Duty
Utilize the 402N push force for precise pressing or locating tasks where a fixed end-stop would be too rigid.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-10 the Right Cylinder?
Select this 32 mm bore when an application requires precise end-position tuning within a 125 to 135 mm window, stepping down from a 40 mm bore (which yields 628N push at 0.5 MPa) for lighter duties. The 12 mm rod and M10x1.25 thread handle moderate side loads, but because the stroke is 135 mm, ensure an external guide supports any heavy lateral forces. To replace an ISO 15552 cylinder, match the 32 mm bore, 135 mm stroke, 10 mm adjustment, PT G1/8 port, and the specified mounting interface.
Choose this adjustable variant over a fixed-stroke SAI when you need machine setup flexibility or product-size changeovers. The adjuster screw and the 27 mm variable air cushion at both ends only decelerate the travel end; they do not function as a lock. If the mechanism requires true load-holding without live air pressure, integrate an external rod lock or pilot-operated check valve.
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 SAIJ32BX135-10 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 Newtons of push force and 345 Newtons of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 125 to 135 mm, but it only sets the end position and does not lock the load without live air.
