About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-10S
The AirTAC SAIJ100X175-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 5497N of push force at 0.7 MPa. It features a SUS304 stainless steel rod and a PT tapered port. By turning the rear screw, you can fine-tune the effective travel down by 10 mm, creating a precise 165-175 mm usable window for exact end-position tuning at commissioning without swapping the hardware.
This extruded aluminum profile cylinder includes a magnet for CMSE reed and DMSE electronic sensors, mounting via a reduced SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). The rear adjuster acts purely as a travel stop to set deceleration, not as a lock; for load-holding without live air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-10S Is Used
Variable End-Stop Tuning
Dial in the exact 165-175 mm travel window during machine commissioning to accommodate minor mechanical tolerances without machining new hard stops.
Product Changeover
Quickly adjust the rear screw by up to 10 mm when switching product sizes on a packaging line, reducing setup downtime.
Corrosion-Resistant Actuation
Leverage the 5497N push force and SUS304 stainless steel rod for heavy-duty positioning tasks in washdown or mildly corrosive environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-10S the Right Cylinder?
Choose this 100 mm bore when 50 mm (1374N at 0.5 MPa) lacks thrust but stepping up to 125 mm (8590N at 0.7 MPa) is overkill. The 10 mm adjustment range is ideal for applications needing slight end-position corrections during machine setup or product changeover, avoiding the need to bolt on external stops. The SUS304 rod provides excellent corrosion resistance for harsh environments.
To match this ISO 15552 cylinder for a replacement, verify the 100 mm bore, 175 mm stroke, 10 mm adjuster, PT port type, and the -S magnet. Since the nominal stroke is under the 1500 mm maximum, it is a standard configuration, though any stroke of 300 mm or more requires an external guide to manage side loads.
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 SAIJ100 Adjustable Cylinder SAIJ100BX175-10S FAQ
At 0.7 MPa operating pressure, this 100 mm bore double-acting cylinder provides 5497N of push force and 5149N of pull force. It can deliver up to 7068N push at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 175 mm nominal stroke by up to 10 mm, resulting in a 165-175 mm usable travel window. It sets the travel end and deceleration point but does not lock the load without live air pressure.
