About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-20
The AirTAC SAIJ200X55-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers immense thrust, pushing 15708N and pulling 15080N at 0.5 MPa, making it suitable for heavy-duty pressing. The integrated rear stopper allows you to fine-tune the effective travel within a 35-55 mm window without adding external physical stops.
This model features a robust 40 mm carbon steel piston rod and a G3/4 PT tapered port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Because the rear adjuster acts purely as a travel stop and the built-in air cushions manage deceleration, this cylinder cannot hold a load dynamically without continuous 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 SAIJ200X55-20 Is Used
Machine Commissioning
Allows operators to fine-tune the rear stopper during initial machine setup, achieving precise end-position tuning without installing external bumpers.
Product Changeover
Ideal for production lines running varied product sizes, letting technicians quickly adjust the cylinder's effective stroke by up to 20 mm on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-20 the Right Cylinder?
Select this 200 mm bore cylinder when an application requires massive force—up to 15708N at just 0.5 MPa—and benefits from dialing in the exact end-of-stroke position during commissioning. If your setup needs slightly less push force, stepping down to a 160 mm bore yields 10053N at 0.5 MPa. The adjustable stroke is ideal for product changeovers where the precise end-stop distance varies slightly, avoiding the need to physically swap out a fixed-stroke SAI cylinder.
For ISO 15552 replacement matching, ensure your parameters align: 200 mm bore, 55 mm stroke, 20 mm adjustment range, G3/4 PT port, and standard carbon steel rod. Note that SAIJ supports a specific mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your machinery requires fail-safe load holding without live air, consider the SAIL or BSAI series instead, as this adjuster is not a locking mechanism.
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 SAIJ200X55-20 FAQ
The rear adjuster acts as a mechanical stopper that lets you shorten the nominal 55 mm stroke by up to 20 mm. This provides a usable travel window of 35-55 mm, allowing precise end-position tuning without swapping the cylinder.
It operates at speeds between 30-500 mm/s.
