About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X45-40
The AirTAC SAIJ200X45-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. With a nominal 45 mm stroke and a 40 mm adjustment range, this model provides a usable travel window of 5 to 45 mm, allowing precise end-position tuning without swapping hardware.
This extruded aluminum profile cylinder features a robust 40 mm carbon steel rod with an M36x2 thread, designed to handle substantial side loads. It operates at speeds of 30-500 mm/s and includes variable air cushions at both ends to decelerate heavy masses smoothly. The tapered PT port and integrated sensor grooves on both sides ensure flexible and leak-free integration.

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 SAIJ200X45-40 Is Used
Heavy Press Tuning
Fine-tune the 5-45 mm travel window during machine commissioning to achieve the exact contact pressure needed for heavy pressing operations without mechanical modifications.
Product Changeover
Rapidly adjust the end-stop position on a production line when switching between components of varying thicknesses, utilizing the 40 mm adjustment range.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X45-40 the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when your application requires extreme force, but the exact end-stop distance varies by product type. Instead of adding external stops or changing cylinders during a changeover, the rear adjuster lets you dial in the 5-45 mm travel window on the spot.
For ISO 15552 interchangeability, match the 200 mm bore, 45 mm stroke, 40 mm adjustment, PT tapered port, and carbon steel rod. Because the stroke is under 300 mm, external guide requirements are relaxed, though the heavy mass still necessitates secure mounting. Note that the rear screw acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ200X45-40 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of push force.
The rear adjuster acts as an external stopper that lets you mechanically shorten the effective stroke from 45 mm down to 5 mm. This allows precise end-position tuning at commissioning without needing to replace the cylinder or add external stops.
