About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX60-30
The AirTAC SAIJ200X60-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations requiring exact end-position tuning. It integrates a rear stopper mechanism that allows you to shorten the effective travel from its 60 mm nominal stroke down to 30 mm, creating a highly versatile 30-60 mm usable stroke window. Delivering a formidable 28274N of push force at 0.9 MPa, it is built to handle substantial loads without requiring a cylinder swap during machine commissioning.
This configuration features a robust SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU is supplied without a magnet, adding an -S variant enables compatibility with AirTAC CMSE reed and DMSE solid-state sensors. The rear adjuster functions purely as a travel stop to set deceleration points, not as a locking device.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX60-30 Is Used
Heavy Press Tonnage Tuning
Dial in the exact 30-60 mm travel window during heavy press commissioning to ensure precise clamping force without over-traveling the tooling.
Variable Product Changeover
Quickly adapt the end-stop position on a packaging line when switching between different large-scale product sizes, eliminating the need to physically swap cylinders.
Large Assembly Positioning
Position heavy structural components accurately by using the rear adjuster to fine-tune the retraction point, ensuring perfect alignment before final mating.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX60-30 the Right Cylinder?
Selecting this 200 mm bore model is appropriate when your application demands immense thrust, offering 21991N push at 0.7 MPa, which dwarfs the 15708N available from the neighbouring 160 mm bore at the same pressure. You would choose this adjustable-stroke SAIJ over a fixed SAI when a process requires variable end-stops to accommodate product size changeovers on a line. Because the nominal 60 mm stroke is relatively short for this massive bore, side-loading is less of a concern than with longer strokes, but external guides are still recommended for heavy off-center loads. To replace an ISO 15552 cylinder, match the 200 mm bore, 60 mm stroke, 30 mm adjustment, PT G3/4 ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster and air cushions do not hold the load without live air; for true load-holding without pressure, use an AirTAC SAIL or BSAI cylinder.
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 SAIJ200BX60-30 FAQ
At its maximum operating pressure of 1.0 MPa, this 200 mm bore cylinder generates 15708N of push force and 15080N of pull force. At 0.7 MPa, it provides 21991N of push force.
The rear adjusting screw acts as an external stopper that trims the effective travel. For the SAIJ200X60-30, you can shorten the 60 mm nominal stroke by up to 30 mm, yielding a usable travel window of 30 to 60 mm. The adjuster sets the end position but does not lock the load without live air pressure.
