About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-40S
The AirTAC SAIJ200X165-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 165 mm nominal travel by up to 40 mm. This creates a precise 125-165 mm usable end-position window, ideal for fine-tuning machinery setup without swapping components. It delivers substantial thrust, providing 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the G3/4 port ensures high airflow for its 30-500 mm/s operating speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-40S Is Used
Heavy Machinery Setup
Provides 15708 N of push force for heavy press operations while allowing 40 mm of rear adjustment to perfectly dial in the 125-165 mm travel window during commissioning.
Product Size Changeover
Enables rapid line changeovers by adjusting the retract end-position on the fly, accommodating different product lengths without replacing the cylinder or adding external stops.
High-Force Positioning
Leverages the robust 40 mm rod and SUS420J2 stainless steel construction to handle substantial side loads in precision manufacturing fixtures.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-40S the Right Cylinder?
Select this 200 mm bore cylinder when an application requires extreme force combined with variable end-stops; if lower thrust is acceptable, stepping down to a 160 mm bore yields 10053 N push force at 0.5 MPa. The adjustable stroke is chosen over a fixed SAI cylinder when commissioning requires exact end-position tuning or frequent product-size changeovers. For any stroke at or above 300 mm, an external guide is recommended to prevent excessive side-loading on the rod.
To match this ISO 15552 dimensionally interchangeable cylinder, specify: 200 mm bore, 165 mm nominal stroke, 40 mm adjustment, PT tapered port threads, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, consider an external rod lock or the AirTAC SAIL/BSAI series.
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 SAIJ200AX165-40S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 165 mm nominal stroke by up to 40 mm, resulting in a usable travel window of 125-165 mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
