About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-75
The AirTAC SAIJ200X500-75 is a double-acting ISO 15552 profile cylinder featuring a 200mm bore and a 500mm stroke. An integrated rear adjusting screw allows you to dial back the travel by up to 75mm, creating a precise 425-500mm usable window for commissioning without external stops.
This heavy-duty extruded aluminum barrel includes sensor grooves on both sides and uses a substantial 40mm carbon steel rod with an M36x2 thread. It is equipped with variable air cushions at both ends measuring 50mm. Note that the rear adjuster acts solely as a travel stop to set deceleration endpoints; it does not hold the load without live air pressure.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-75 Is Used
Heavy Machinery Setup
Fine-tune the 425-500mm travel window during large equipment commissioning to dial in exact retract positions without machining custom external stoppers.
Product Size Changeover
Adjust the rear stopper by up to 75mm on packaging lines to accommodate different pallet or product sizes rapidly without changing the actuator.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-75 the Right Cylinder?
If you need less force, stepping down to a 160mm bore yields 10053N at 0.5 MPa. The 75mm adjustment range is ideal for product-size changeovers on a line, letting you fine-tune the retract end-position quickly instead of swapping the cylinder or adding mechanical stops.
For load-holding without continuous air pressure, this standard SAIJ is insufficient as the rear adjuster is not a brake; you should consider the SAIL series with an air-released lock, the BSAI clamp-lock, or an external rod lock. Because the 500mm stroke is substantial, the 40mm rod and M36x2 thread still require an external guide to prevent excessive side-loading on the piston. As a true ISO 15552 cylinder, it is dimensionally interchangeable with ISO 15552 cylinders and uses PT tapered G3/4 ports. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ200X500-75 FAQ
The rear adjuster acts as an external stopper that trims the effective travel. For this model, the 500mm nominal stroke can be dialed back by up to 75mm, providing a usable travel window of 425-500mm. It sets the end position but does not lock the load without live air.
The operating speed range is 30-500 mm/s, and it features 50mm variable air cushions at both ends to manage deceleration.
