About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-100S
The AirTAC SAIJ32X650-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 650 mm nominal stroke that can be fine-tuned backward by up to 100 mm, yielding a practical usable travel window of 550 to 650 mm. Within its 32 mm bore, it delivers 402 Newtons of push force at 0.5 MPa and reaches speeds of 30-800 mm/s.
This variant features an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster functions strictly as a travel stop for end-position tuning rather than a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-100S Is Used
Changeover Calibration
Dial in the 550-650 mm travel window during product size changeovers to set exact retract positions without adding external physical stops.
Sorting Diverter
Adjust the stroke on the fly for a pneumatic diverter gate handling varying package lengths on a packaging line.
End-Stop Trimming
Fine-tune the final retract position of a tooling plate during machine setup to avoid mechanical binding.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-100S the Right Cylinder?
Select this 32 mm bore unit when an application requires precise end-position tuning during commissioning or product changeovers without swapping the cylinder. If the 402 Newtons of push force at 0.5 MPa is insufficient, stepping up to the 40 mm bore yields 628 Newtons. To replace this ISO 15552 cylinder accurately, match the 650 mm stroke, 100 mm adjustment range, PT tapered port thread, and the -S magnet requirement.
Because the 650 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 rod thread have limited side-load capacity; an external guide rail is recommended to support the load. For applications needing to hold a position without live air pressure, note that the rear stopper and air cushion cannot act as a brake—consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ32AX650-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 Newtons of push force and 345 Newtons of pull force. At the maximum 1.0 MPa pressure, it achieves 82 kgf.
The rear adjuster acts as a stopper that allows you to shorten the effective stroke by up to 100 mm, creating a usable travel window of 550 to 650 mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
