About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-30
The AirTAC SAIJ200X750-30 is a double-acting ISO 15552 profile cylinder featuring a 750 mm nominal stroke and a rear-mounted stroke adjuster. This external stopper allows you to dial back the effective travel by up to 30 mm, creating a precise 720-750 mm usable window for fine-tuning end positions during commissioning. As an extruded aluminum profile barrel design, it integrates sensor grooves on both sides and is dimensionally interchangeable per ISO 15552 standards.
Delivering massive thrust, this 200 mm bore generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa. The piston rod utilizes a 40 mm SUS420J2 stainless steel construction (code A) with an M36x2 thread, providing excellent rigidity and side-load resilience. Fluid must be filtered air, operating at pressures between 0.15 and 1.0 MPa, with PT tapered port threading (G3/4) for secure pneumatic connections.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-30 Is Used
Heavy Press Tuning
Fine-tune the 720-750 mm travel window during machine setup to dial in the exact pressing depth for heavy industrial components without external stopper blocks.
Product Changeover
Quickly adjust the end-stop position on an automated line to accommodate different large product sizes, reducing downtime between production runs.
Heavy Duty Ejection
Leverage the 15708 N push force at 0.5 MPa to eject heavy metal parts from molds, using the rear adjuster to time the full retraction distance accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-30 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme thrust that smaller bores cannot provide, such as stepping up from a 160 mm bore that yields 10053 N push force at 0.5 MPa. The adjustable stroke is ideal for variable end-stop requirements and product-size changeovers, eliminating the need to physically swap cylinders or bolt on external stops. For applications needing exact positioning, the rear screw acts purely as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series.
With a 750 mm stroke, the long unsupported piston rod requires an external guide to prevent excessive side-loading and premature seal wear. This model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Operating speed is capped at 30-500 mm/s for this large bore size.

- ✓ 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 SAIJ200AX750-30 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the 750 mm nominal stroke by up to 30 mm, giving a usable travel range of 720 to 750 mm. This stopper only sets the end position and deceleration; it does not lock or hold the load without continuous air pressure.
