About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-50
The AirTAC SAIJ200X65-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 15 to 65 mm, enabling precise end-position tuning at commissioning without swapping out the entire unit. Built with a robust 40 mm carbon steel piston rod and a G3/4 PT tapered port, it delivers substantial thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
This extruded aluminum barrel design includes sensor grooves on both sides for CMSE or DMSE switches, though this specific configuration ships without a magnet. The rear adjustment mechanism acts strictly as a mechanical stop to decelerate the load, not as a lock; for load-holding without live air pressure, an external rod lock or a SAIL cylinder is required.

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 SAIJ200X65-50 Is Used
Variable End-Stop Tuning
Dial in the exact 15 to 65 mm travel window during machine commissioning to accommodate varying product sizes without replacing the cylinder.
Product Changeover Systems
Quickly adjust the retract end-position on packaging or handling lines during format changes, saving downtime compared to fixed-stroke alternatives.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-50 the Right Cylinder?
If your setup requires less energy, stepping down to a 160 mm bore still provides 10053 N at 0.5 MPa, whereas moving up is impossible within this standard range. The adjustable stroke is ideal for product changeovers, allowing operators to dial in the exact 15-65 mm travel window rather than machining external stops or relying on a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 65 mm nominal stroke, 50 mm adjustment range, G3/4 PT port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is short at 65 mm, side-loading risks are minimal, but the heavy 40 mm rod thread handles high side loads effectively. Note that the operating speed is 30-500 mm/s for this large bore.
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 SAIJ200X65-50 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 50 mm. For this 65 mm nominal stroke model, it creates a usable travel window of 15 to 65 mm, though it only decelerates the load and does not hold it without live air.
