About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-30
The AirTAC SAIJ200X175-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a massive 15708N push force at 0.5 MPa (up to 3204 kgf at 1.0 MPa), making it suitable for heavy-duty operations. The integrated adjuster allows you to trim the 175mm nominal stroke back by up to 30mm, creating a precise 145-175mm usable travel window for exact end-position tuning.
This variant features a SUS420J2 stainless steel rod (code A) and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic sensors. The rear adjustment mechanism acts purely as a travel stop to fine-tune the deceleration point and does not lock the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-30 Is Used
Heavy Machinery Setup
Dial in the exact 145-175mm end-stop during heavy machinery commissioning without installing external physical stops.
Product Changeover
Quickly adjust the retract position on production lines handling varying product sizes by turning the rear screw.
Press Fit Tuning
Fine-tune the stroke end-point for heavy pressing applications requiring precise depth control and 1500 kgf of force.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-30 the Right Cylinder?
Choose this 200mm bore cylinder when your application requires extreme thrust that exceeds the 10053N push force of the neighbouring 160mm bore at 0.5 MPa. The adjustable stroke is ideal for machine setup and product changeover, allowing you to dial in the exact end-stop without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, this cylinder cannot hold position on its own; you should look at the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match these exact specifications: 200mm bore, 175mm stroke, 30mm adjustment range, PT port threads, and no magnet (-S not specified). Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke is under 300mm, side-load concerns are minimal, but the heavy 40mm rod and M36x2 thread provide excellent rigidity for demanding tasks.
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 SAIJ200 Adjustable Cylinder SAIJ200AX175-30 FAQ
At a 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 175mm nominal stroke by up to 30mm, providing a usable travel window of 145-175mm. It only sets the end position and does not lock the load without live air.
