About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-40
The AirTAC SAIJ200X65-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 65 mm stroke back by up to 40 mm. This yields a highly versatile 25-65 mm usable travel window, enabling precise end-position tuning at commissioning without swapping the barrel or adding external stops. Built with a robust 40 mm carbon steel rod and a PT tapered G3/4 port, it delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
Because the adjuster acts purely as a mechanical stop on the retract end, it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. This model utilizes a variable air cushion at both ends (50 mm cushion length) and features an extruded aluminum barrel with sensor grooves on both sides, compatible with CMSE reed and DMSE electronic sensors if a magnet is specified later.

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 SAIJ200X65-40 Is Used
Heavy-Duty Pressing
Dial in the exact 25-65 mm travel window during machine setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the retract end-stop on a packaging line when switching to a different product size, saving hours of retooling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-40 the Right Cylinder?
If your application requires less thrust, stepping down to a 160 mm bore yields 10053 N, whereas moving up from a 125 mm bore (6136 N) to this size handles heavy-duty pressing. The 40 mm adjustment range is ideal for product-size changeovers on a line, allowing you to dial in the exact 25-65 mm travel window on the fly instead of machining custom spacers. When replacing an ISO 15552 cylinder, match the 200 mm bore, 65 mm stroke, 40 mm adjustment, G3/4 PT port, and your required mounting option. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, 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 SAIJ200X65-40 FAQ
The rear adjuster screw acts as a mechanical stop that shortens the retract stroke. For this model, you can trim the nominal 65 mm stroke back by up to 40 mm, giving an adjustable travel window of 25 to 65 mm.
The maximum thrust is 3204 kgf at 1.0 MPa.
