About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-50
The AirTAC SAIJ32X260-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the effective travel by up to 50 mm. This creates a usable 210-260 mm travel window, letting you fine-tune the retract end position at commissioning without swapping out the entire unit. It delivers 402 N of push force at 0.5 MPa, making it well-suited for compact automation tasks.
This model incorporates a SUS420J2 stainless steel rod for improved corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet, meaning position sensing via CMSE or DMSE switches is not supported without adding the -S option.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-50 Is Used
Machine Changeover
Quickly fine-tune the 210-260 mm retract position when switching between product sizes on a packaging line, avoiding the need to physically swap cylinders.
End-Stop Calibration
Dial in the exact end position during commissioning using the rear screw, allowing precise mechanical calibration without adding bulky external stoppers.
Light Assembly Automation
Utilize the 402 N push force at 0.5 MPa for compact assembly tasks where a 12 mm rod and variable stroke limits are sufficient for the workflow.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-50 the Right Cylinder?
Selecting the SAIJ32X260-50 is ideal when your machine setup requires variable end-stops or frequent product changeovers that demand precise retract positioning. If your application requires less force, stepping down is not an option below 32 mm, but if you need significantly more thrust, the 40 mm bore provides 628 N at 0.5 MPa. Because this cylinder features a 260 mm stroke, it is important to provide an external guide to support the load and prevent excessive side-loading on the 12 mm rod.
The rear adjuster acts strictly as a mechanical stop to set deceleration and travel limits; it does not hold the load without live air pressure. For applications requiring true load-holding in the event of pressure loss, consider the SAIL or BSAI series instead. To match this ISO 15552 interchangeable cylinder exactly, confirm the 32 mm bore, 260 mm stroke, 50 mm adjustment, PT G1/8 port, and mounting choices limited to Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAIJ32AX260-50 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 260 mm nominal stroke by up to 50 mm, providing a usable travel window of 210 to 260 mm. It only sets the travel end and does not lock the load without live air pressure.
