About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-20
The AirTAC SAIJ200X750-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 28274N at 0.9 MPa. Its 750mm nominal stroke incorporates a 20mm adjustment range, providing a usable travel window of 730-750mm for precise end-position tuning during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This heavy-duty unit features a 40mm SUS420J2 stainless steel rod and PT tapered port threads. The rear adjuster acts purely as a travel stop to dial in the exact retract distance without swapping components, while the variable air cushions handle end-of-stroke deceleration across its 30-500mm/s speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-20 Is Used
Heavy Machinery Setup
Fine-tunes the 730-750mm retract end-stop during large equipment commissioning without machining new hard stops.
Product Line Changeover
Dials in the exact stroke distance for varying large product sizes on a conveyor line quickly and repeatably.
Large Press Positioning
Provides adjustable end-positioning for heavy pressing or lifting tasks requiring up to 28274N of force.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-20 the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when an application requires over 28000N of push force and exact end-position tuning, stepping up from a 160mm bore that yields 18095N at 0.9 MPa. The adjustable stroke is ideal for product changeovers on large machinery, allowing operators to fine-tune the 730-750mm travel window without adding external stops. For a direct ISO 15552 replacement match, verify the 750mm stroke, 20mm adjustment, PT G3/4 port, and mounting style.
Because the stroke is 750mm, the heavy load should be externally guided to prevent excessive side-loading on the 40mm rod. Note that the rear stopper and air cushions do not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX750-20 FAQ
At an operating pressure of 0.9 MPa, this 200mm bore cylinder generates a push force of 28274N and a pull force of 25272N. The maximum push force is 15708N at 0.5 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 20mm, creating a usable travel window of 730-750mm from the 750mm nominal stroke. It functions as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
