About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX145-40S
The AirTAC SAIJ200X145-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa, driven by its 200mm bore and G3/4 port. The integrated -40mm adjustment mechanism creates a usable travel window between 105 and 145mm, allowing you to dial in the exact retract end-position without swapping out the barrel.
Equipped with a SUS304 stainless steel rod (option B), this unit is built for corrosive environments and carries a 50mm cushion length to decelerate heavy loads. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it works seamlessly with AirTAC CMSE reed and DMSE solid-state sensors. The rear stopper acts purely as a travel limit and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX145-40S Is Used
Heavy Press Fine-Tuning
Dial in the exact 105-145mm retract distance during heavy-duty pressing operations to accommodate varying material thicknesses without changing the cylinder.
Product Line Changeover
Quickly adjust the rear end-stop on a packaging line when switching to a different product size, utilizing the 40mm adjustment range for rapid setup.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for high-thrust clamping tasks in washdown or chemical environments while tracking position with DMSE sensors.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX145-40S the Right Cylinder?
Choose this 200mm bore variant when your application requires extreme force that smaller bores cannot provide, such as stepping up from a 160mm cylinder which offers 10053N push force at 0.5 MPa. The adjustable stroke is highly beneficial during machine commissioning or product changeover, enabling you to fine-tune the 105-145mm travel window on the fly instead of machining external stops or installing a fixed-stroke SAI cylinder.
For load-holding requirements without continuous air pressure, note that this cylinder's adjuster is a stop, not a lock; you would need to specify a SAIL or BSAI series cylinder instead. When matching an ISO 15552 replacement, verify a 200mm bore, 145mm stroke, 40mm adjustment range, PT tapered port threads, SUS304 rod material, and the -S magnet option. Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200BX145-40S FAQ
At 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 screw allows you to mechanically shorten the nominal 145mm stroke by up to 40mm, creating a usable travel window of 105 to 145mm. This stopper only limits the travel end and requires live air to hold the load.
