About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-10
The AirTAC SAIJ200X270-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 260-270mm usable travel window for fine-tuning the retract end position. Delivering 15708N of push force at 0.5MPa, this massive 200mm bore unit is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance. It uses PT tapered port threads and operates without a magnet.
The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. Because the 270mm stroke is well below the 1500mm maximum standard stroke, this is a stock configuration. The rear adjuster acts strictly as a mechanical stop to dial in end positions during commissioning without adding external stops; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-10 Is Used
Heavy Press Tuning
Dial in the exact 260-270mm end position during heavy press commissioning to accommodate material thickness variations without re-engineering the fixture.
Product Changeover
Adjust the retract stop by up to 10mm on the fly when switching between different sized products on a high-thrust handling line.
Large Mold Setup
Fine-tune the end-of-stroke position for large molding or forming tools, leveraging the 15708N push force and SUS304 rod for rugged environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-10 the Right Cylinder?
Choose this 200mm bore cylinder when your application requires extreme thrust, such as 15708N push or 15080N pull at 0.5MPa. If you need less force, stepping down to a 160mm bore yields 10053N push at 0.5MPa, while moving up is impossible as 200mm is the largest standard SAIJ size. The adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers, allowing up to 10mm of retraction tuning without swapping the cylinder.
For ISO 15552 replacement matching, ensure the target unit shares the 200mm bore, 270mm stroke, PT G3/4 port, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This profile cylinder omits FB, CA, CB, and CR mounts. Since the 270mm stroke is under 300mm, side-load risks are moderate, but the 40mm rod and M36x2 thread handle high stresses well. For load-holding without live pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
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 SAIJ200BX270-10 FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder generates 15708N of push force and 15080N of pull force. It can reach a maximum of 3204 kgf at 1.0MPa.
The rear adjuster screw lets you shorten the 270mm nominal stroke by up to 10mm, providing a usable travel window of 260-270mm. This mechanical stop sets the end position but does not lock or hold the load without live air pressure.
