About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-50
The AirTAC SAIJ200X100-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, designed to fine-tune the end-of-travel position during machine commissioning. It provides a usable travel window of 50 to 100 mm, allowing you to dial back the nominal stroke by up to 50 mm without bolting on external stops or swapping the barrel. Built with a robust 40 mm carbon steel rod and a PT G3/4 port, it delivers immense thrust up to 15708 N at 0.5 MPa and 21991 N at 0.7 MPa.
This heavy-duty actuator features an extruded aluminum barrel with sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjustment mechanism acts strictly as a travel stop to set deceleration endpoints, not as a load-holding brake. For applications requiring position retention without live air pressure, you must integrate an external pilot-operated check valve or select a related AirTAC locking cylinder like the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-50 Is Used
Heavy Pressing Operations
Delivers up to 21991 N of thrust at 0.7 MPa for heavy assembly and pressing tasks, with a 50-100 mm travel window to fine-tune the exact pressing depth.
Product Changeover Setup
The rear adjuster allows operators to quickly shorten the stroke by up to 50 mm during product size transitions without replacing the cylinder or adding mechanical stops.
Automated Heavy Machinery
Ideal for large-scale automated machinery requiring a durable double-acting profile cylinder with variable end-stops to accommodate multiple fixture heights.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-50 the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when your machinery requires extreme pushing power combined with variable end-stop positioning. If your application needs slightly less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, whereas this 200 mm model provides maximum holding and thrust capabilities. Choose the SAIJ adjustable-stroke variant over the fixed SAI series when you need precise end-position tuning during product changeovers. To match this ISO 15552 interchangeable cylinder, verify your parameters: 200 mm bore, 100 mm nominal stroke, 50 mm adjustment, PT G3/4 port, and standard SUS420J2 stainless steel rod material. Because the nominal stroke of 100 mm is below the 300 mm threshold, side-loading risks are minimized, though the heavy 40 mm rod thread inherently handles greater side loads than smaller bores.
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.
