About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X650-10
The AirTAC SAIJ32X650-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract position. With a nominal 650 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 640 to 650 mm. This adjustability enables precise end-position calibration at commissioning or during product changeovers without swapping the cylinder or adding external stops. In the 32 mm bore class, it delivers 402 N of pull force at 0.5 MPa and 563 N of push force at 0.7 MPa.
The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. This configuration uses a standard carbon steel piston rod with an M10x1.25 thread and a PT tapered G1/8 port. The rear adjuster acts strictly as a travel stop for end-position tuning and does not hold the load without live air pressure. For applications requiring position holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X650-10 Is Used
Machine Setup Calibration
Dial in the exact retract position within the 640-650 mm window during initial machine commissioning without machining new stopper blocks.
Product Size Changeovers
Quickly adapt the end-of-stroke position on packaging lines when switching between different product sizes or formats.
Variable End-Stop Positioning
Fine-tune the retract distance by up to 10 mm to accommodate varying material lengths or tooling depths on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X650-10 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires exact end-position tuning within a 640-650 mm travel window. If you need higher force, stepping up to the 40 mm bore provides 528 N of pull force at 0.5 MPa, but increases the footprint. The SAIJ32X650-10 is selected over a fixed-stroke SAI model when machine setups involve variable end-stops or frequent product size changeovers. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. For ISO 15552 replacement matching, verify the 650 mm stroke, 10 mm adjustment, PT G1/8 port, and carbon steel rod. Because the stroke is 650 mm, an external guide is recommended to prevent excessive side-loading on the rod.

- ✓ 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 SAIJ32X650-10 FAQ
At 0.5 MPa, the 32 mm bore provides 402 N of pull force and 402 N of push force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 640-650 mm travel window. It functions as a travel stop and does not lock the load without live air pressure.
