About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-50
The AirTAC SAIJ200X800-50 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. A rear adjustment screw allows you to trim the nominal 800 mm stroke back by up to 50 mm, creating a 750-800 mm usable travel window for exact setup at commissioning. Delivering 15708 N of push force and 15080 N of pull force at 0.5 MPa, this 200 mm bore unit handles massive loads without needing external stops.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and pairs with PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches. Because the 800 mm stroke is substantial, an external guide is strongly recommended to prevent excessive side-loading on the 40 mm rod, ensuring the internal cushions and rear stopper can effectively decelerate the mass.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-50 Is Used
Heavy Press Tuning
Fine-tune the end position of large presses during commissioning, using the 750-800 mm travel window to dial in the exact clamping distance without external shims.
Product Changeover
Adapt large-scale conveyor diverter arms to different package sizes on the fly by adjusting the rear stopper, eliminating the need to swap cylinders.
Large Assembly Jigs
Position heavy structural components accurately during assembly, relying on the 15708 N push force and the SUS420J2 rod for durable, repeatable cycling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-50 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires up to 15708 N of push force at 0.5 MPa. If your load requirements are lower, stepping down to a 160 mm bore provides 10053 N of push force, which may offer a more compact and economical solution. The adjustable stroke is ideal for production lines that undergo frequent product-size changeovers, allowing operators to fine-tune the end position without swapping out the entire cylinder or adding external mechanical stops.
When replacing an ISO 15552 cylinder, verify that the 200 mm bore, 800 mm stroke, 50 mm adjustment range, G3/4 PT ports, and standard mounting interface match your existing footprint. The SAIJ series supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster acts solely as a travel stop and does not hold the load without live air pressure; for true position holding, consider the SAIL or BSAI series. Operating speed for this bore is 30-500 mm/s.
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 SAIJ200AX800-50 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 800 mm nominal stroke by up to 50 mm, providing a usable travel window of 750 to 800 mm. It only sets the end position and must not be relied upon as a lock or brake to hold the load without continuous air pressure.
