About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-10
The AirTAC SAIJ32X550-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position. With a nominal 550 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 540-550 mm. This adjustability enables precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers a push force of 402 N at 0.5 MPa, scaling up to 724 N at 0.9 MPa.
This model features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for load-holding applications, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-10 Is Used
Machine Changeovers
Dial in the exact 540-550 mm retract position during product size transitions without machining new hard stops.
Variable End Stops
Fine-tune the stopping point of a transfer carriage on a conveyor line by adjusting the rear screw.
Assembly Calibration
Trim the stroke up to 10 mm during commissioning to perfectly seat parts without applying excessive force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-10 the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires exact end-position tuning within a 540-550 mm travel window. If your setup needs less force, stepping down is not an option below 32 mm in this series, but if higher force is required, a 40 mm bore provides 628 N at 0.5 MPa. The adjustable stroke is ideal for product-size changeovers on a line, whereas a fixed SAI cylinder lacks this commissioning flexibility.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 550 mm stroke, 10 mm adjustment, PT G1/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the stroke is 550 mm, the 12 mm rod requires external guiding to prevent excessive side-loading on the seals. This model does not include a magnet; adding a -S suffix enables CMSE reed or DMSE electronic sensors.

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 SAIJ32AX550-10 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. At 0.9 MPa, the push force increases to 724 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a 540-550 mm usable travel window. It functions as a mechanical stop for end-position tuning and is not a locking device.
