About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X85-30
The AirTAC SAIJ200X85-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing with 15708N and pulling with 15080N at a 0.5 MPa operating pressure. By turning the rear stopper screw, you achieve a usable travel window of 55-85mm, allowing precise end-position tuning without adding external stops.
This 200mm bore unit uses a PT G3/4 port and a robust 40mm carbon steel rod with an M36x2 thread. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ200X85-30 Is Used
Press Tonnage Tuning
Dial in the exact 55-85mm contact distance for heavy pressing operations, adjusting the end-stop on the fly without replacing the cylinder.
Product Size Changeover
Quickly reconfigure the stroke window when switching between different product sizes on a heavy-duty assembly line.
Heavy Fixture Positioning
Fine-tune the retracted position of large manufacturing fixtures to accommodate varying material thicknesses safely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X85-30 the Right Cylinder?
Select this adjustable model when your setup requires variable end-stops for product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder during commissioning. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ cannot hold loads without live air, so consider an SAIL or BSAI cylinder for fail-safe load holding.
For an exact ISO 15552 replacement, match the 200mm bore, 85mm nominal stroke, 30mm adjustment range, PT G3/4 port, and standard carbon steel rod without a magnet. Although the stroke is short, the 40mm rod handles high side loads, but any long unsupported travel still requires an external guide to prevent binding.
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 SAIJ200X85-30 FAQ
It can deliver up to 3204 kgf at the maximum 1.0 MPa operating pressure.
The rear adjuster screw lets you trim the effective travel back by up to 30mm from the 85mm nominal stroke, creating a 55-85mm usable window. This stopper only sets the travel end and does not lock the load without live air pressure.
