About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX105-50
The AirTAC SAIJ200X105-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, engineered for heavy-duty applications requiring precise end-position tuning. By turning the external stopper at the rear, you can shorten the effective stroke by up to 50 mm, creating a usable travel window of 55 to 105 mm without swapping the barrel. This profile cylinder integrates a robust 40 mm SUS304 stainless steel rod and a PT tapered port thread, providing excellent resistance to side loads and environmental corrosion.
Delivering substantial thrust, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa. The extruded aluminum barrel features sensor grooves on both sides for straightforward position feedback. It is important to note that the rear adjuster acts solely as a travel stop to decelerate the load alongside the air cushions; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX105-50 Is Used
Heavy Press Tuning
Dial in the exact 55 to 105 mm travel window during heavy press setup to accommodate varying material thicknesses without mechanical rework.
Product Changeover
Quickly adjust the end-stop on automated assembly lines when switching product sizes, leveraging the 50 mm trim range for rapid format resets.
High-Force Positioning
Utilize the 15708 N push force at 0.5 MPa to move heavy pallets or tooling, relying on the rear stopper to set precise retract positions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX105-50 the Right Cylinder?
Select this 200 mm bore cylinder when your machinery demands high force combined with variable end-stops for product changeovers. If your application requires less thrust, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, whereas staying with the 200 mm bore ensures maximum power. The adjustable stroke is chosen over a fixed SAI cylinder when you need fine end-position tuning at commissioning without adding external stops.
For load-holding without continuous live air pressure, this plain SAIJ cylinder is insufficient, as the adjuster is a stop and not a lock; consider the SAIL or BSAI series for pneumatic locking. When replacing an ISO 15552 cylinder, verify the 200 mm bore, 105 mm stroke, 50 mm adjustment, PT port thread, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke exceeds 300 mm in longer variants, an external guide is recommended to manage side loads, though this 105 mm unit handles moderate offsets well via its 40 mm rod.

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 SAIJ200BX105-50 FAQ
The rear adjusting screw acts as an external stopper that lets you shorten the nominal 105 mm stroke by up to 50 mm, providing a usable travel window of 55 to 105 mm. This allows fine-tuning of the retract end-position at commissioning without adding external stops.
At 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers a peak force of 3204 kgf.
