About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-75
The AirTAC SAIJ200X190-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 190 mm travel by up to 75 mm, creating a precise 115-190 mm usable window. Built with a SUS304 stainless steel rod and PT tapered port threads, it delivers massive thrust up to 15708 N at 0.5 MPa. This extruded aluminum barrel design includes sensor grooves on both sides for straightforward positioning feedback.
Because this model uses a rear mechanical stopper rather than a lock, it relies on live air to hold position while the built-in air cushions decelerate the load at travel ends. The generous 75 mm adjustment range is ideal for product changeovers, letting you fine-tune the retract end-position at commissioning without swapping out the entire cylinder or adding external stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-75 Is Used
Heavy Press Positioning
Dial in the exact 115-190 mm retract distance for heavy pressing and forming operations without physically remounting the actuator.
Large Part Changeover
Adjust the end-stop on the fly to accommodate varying large product sizes moving down a heavy-duty conveyor line.
Machine Setup Tuning
Fine-tune the travel end-position during initial machine commissioning to perfectly time the 15708 N push force.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-75 the Right Cylinder?
Select this 200 mm bore actuator when an application requires extreme force combined with variable end-stop positioning, such as heavy material handling. If 15708 N of push force at 0.5 MPa is excessive, stepping down to a 160 mm bore yields 10053 N; conversely, this 200 mm bore is the maximum standard size available. The rear adjuster acts purely as a travel stop and does not hold the load without pneumatic pressure—if true fail-safe load holding is required, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 190 mm stroke, 75 mm adjustment, PT port threads, and standard mounting interface (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Since the usable stroke is 190 mm, ensure external guiding is provided to manage side loads on the 40 mm diameter rod during long travel.
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 SAIJ200BX190-75 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach up to 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 190 mm nominal stroke by up to 75 mm, providing a usable travel window of 115 to 190 mm. It functions as an end-stop to tune the retract position and is not a locking mechanism.
