About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-50S
The AirTAC SAIJ32X100-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a carbon steel piston rod and a built-in magnet (-S) compatible with CMSE reed and DMSE electronic sensors. Providing 402N of push force at 0.5 MPa, it delivers precise motion control for lighter-duty applications.
This model features a 100mm nominal stroke that can be dialed back by up to 50mm, creating a highly versatile 50-100mm usable travel window. The external rear adjusting screw acts as a mechanical stop to fine-tune the retract end-position during commissioning or product changeover without adding external stops. The SAIJ mounting set omits FB, CA, CB, and CR brackets, utilizing a focused subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-50S Is Used
Machine Setup & Changeover
Dial in the exact retract position within the 50-100mm window during line changeovers without swapping out the entire cylinder.
Variable End-Stop Positioning
Use the rear mechanical stop to fine-tune the end-of-stroke position at commissioning, eliminating the need to bolt on external spacers.
Product Size Flexibility
Accommodate varying product dimensions on a conveyor line by adjusting the effective stroke up to 50mm to push different sized parts.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-50S the Right Cylinder?
Choose this 32mm bore when your application requires 402N of thrust at 0.5 MPa, but you need flexibility in the final end-position. The 50mm adjustment range is exceptionally wide, allowing a single cylinder to serve multiple product sizes on a changeover line. If your setup needs more force, stepping up to the 40mm bore yields 628N at 0.5 MPa. Remember that the rear adjuster is a travel stop, not a lock; the cylinder will not hold its load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.
As a dimensionally interchangeable ISO 15552 cylinder, this model matches standard mounting footprints. To configure a replacement, match the 32mm bore, 100mm stroke, 50mm adjustment, PT tapered port threads, and the -S magnet option. The 12mm rod and M10x1.25 thread handle moderate side loads, though long unsupported strokes still require an external guide.
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 SAIJ32X100-50S FAQ
The SAIJ32X100-50-S has a 100mm nominal stroke with a rear adjusting screw that allows you to shorten the effective travel by up to 50mm. This provides a usable travel window of 50-100mm, enabling precise end-position tuning without changing the cylinder itself.
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
