About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-75
The AirTAC SAIJ200X220-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the effective travel anywhere within a 145 to 220 mm window. Using a massive 200 mm bore, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to a maximum output of 3204 kgf at 1.0 MPa. This makes it ideal for heavy-duty pressing or moving substantial masses.
Equipped with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, this unit is built for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept electronic DMSE or reed CMSE switches if position feedback is later required. The rear adjuster acts purely as a travel stop to set deceleration and end positions, so it will not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-75 Is Used
Heavy-Duty Press Tuning
Dial in the exact 145 to 220 mm pressing depth during setup or material changes without swapping out the entire cylinder.
Variable End-Stop Positioning
Adjust the rear stopper on the fly to accommodate different product sizes moving down a heavy manufacturing line.
Large Assembly Calibration
Fine-tune the end-of-travel position for large-scale assembly stations, ensuring perfect alignment before final clamping.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-75 the Right Cylinder?
Select this 200 mm bore model when your application demands extremely high thrust that smaller bores cannot provide; for context, stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The 75 mm adjustment range is highly valuable during machine commissioning or product changeovers, allowing you to dial in the exact end-of-stroke position without adding external physical stops or replacing the cylinder. For any load-holding requirements without continuous air pressure, this standard SAIJ adjuster is not a lock—you should instead explore the AirTAC SAIL (air-released lock) or BSAI (clamp-lock) series.
Because this cylinder features a 220 mm stroke, the long unsupported piston rod requires an external guide to prevent excessive side-loading and premature seal wear. It mounts via a reduced SAIJ interface set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits the FB, CA, CB, and CR foot and pivot brackets. It operates at speeds of 30-500 mm/s and is dimensionally interchangeable per ISO 15552 mounting dimensions.

- ✓ 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 SAIJ200AX220-75 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. The maximum force at 1.0 MPa is 3204 kgf. It operates at a speed range of 30-500 mm/s.
The rear adjuster screw allows you to shorten the nominal 220 mm stroke by up to 75 mm, creating a usable travel window of 145 to 220 mm. It functions as a mechanical stop to tune the end position and does not lock the load without live air pressure.
