About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX475-30S
The AirTAC SAIJ200X475-30-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications. It features a robust 40 mm piston rod and delivers exceptional force, generating 15708 N of thrust at 0.5 MPa and up to 28274 N at 0.9 MPa. A built-in rear adjustment screw allows you to fine-tune the stroke, creating a usable travel window between 445 and 475 mm without requiring external stops. This model includes a SUS304 stainless steel rod for superior corrosion resistance and is equipped with a magnet for position sensing.
Designed for demanding environments, this cylinder omits the FB, CA, CB, and CR mounting interfaces, offering a focused mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The dual-sided sensor grooves support AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection. Operating at speeds of 30-500 mm/s, it utilizes variable air cushioning at both ends to decelerate massive loads smoothly. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX475-30S Is Used
Heavy Pressing
Dial in the exact 445-475 mm end-stop for high-force pressing and forming tasks, ensuring perfect crush depth without adding external stopper blocks.
Machine Changeover
Quickly adjust the retract position during product size transitions on a line, using the rear screw to fine-tune the 475 mm stroke to match new part dimensions.
Large Tooling Handling
Move heavy industrial tooling safely, relying on the 40 mm SUS304 rod and smooth air cushions to decelerate massive payloads at the end of travel.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX475-30S the Right Cylinder?
Choosing this 200 mm bore model makes sense when your application requires the upper limits of pneumatic force, as stepping down to a 160 mm bore reduces your 0.5 MPa thrust to 10053 N. The 30 mm rear adjuster is ideal for fine-tuning end positions during machine commissioning or product changeover, providing a 445-475 mm travel window without swapping out the entire cylinder. For applications needing true load-holding without continuous air pressure, a standard SAIJ is insufficient—you should look to the SAIL or BSAI series instead. When replacing an ISO 15552 cylinder, verify your 475 mm stroke, 30 mm adjustment, PT G3/4 port, and the required -S magnet. Given the 475 mm stroke, ensure you use an external guide to manage side-load and prevent rod binding.
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 SAIJ200BX475-30S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. This gives you a usable travel window of 445 to 475 mm, allowing precise end-position tuning at commissioning without replacing the cylinder.
