About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X85-10
The AirTAC SAIJ200X85-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 75-85 mm usable travel window, allowing you to dial back the nominal 85 mm stroke by up to 10 mm.
The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. A standard carbon steel rod and PT tapered port threads are installed. The rear stopper acts purely as a travel end deceleration device, not a lock, so it will 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 SAIJ200X85-10 Is Used
Tooling Setup
Fine-tune the 75-85 mm travel window during machine commissioning to set precise end-stops without external shims.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slight variations in part sizes on the production line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X85-10 the Right Cylinder?
An adjustable stroke is selected over a fixed SAI cylinder when you need fine end-position tuning at commissioning or during product changeover without swapping the cylinder or bolting on external stops. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop.
To match this ISO 15552 cylinder exactly, specify a 200 mm bore, 85 mm stroke, 10 mm adjustment range, PT G3/4 ports, and mounting from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Although the stroke is short, always ensure external guides support the load to prevent excessive side-loading on the rod.
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 SAIJ200X85-10 FAQ
It can deliver a maximum thrust of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 85 mm down to 75 mm. This creates a 10 mm tuning window for exact end-position setup without replacing the cylinder.
