About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX25-10S
The AirTAC SAIJ200X25-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 15-25 mm, allowing you to dial back the 25 mm nominal stroke by up to 10 mm during commissioning without adding external stops. Built for heavy-duty tasks, it delivers 15708 N of push force at 0.5 MPa and utilizes a robust 40 mm SUS304 stainless steel rod with an M36x2 thread to handle substantial side loads.
This variant includes a magnet for position sensing via CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves. It features PT tapered ports sized G3/4, variable air cushions at both ends, and a seal package compatible with standard filtered air. The extruded aluminum barrel design omits tie-rods, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX25-10S Is Used
Press Tuning
Dial in the exact 15-25 mm travel end-stop during machine commissioning to perfect pressing operations without swapping cylinders.
Size Changeover
Quickly adapt the stroke for varying product sizes on a production line using the 10 mm rear adjustment screw.
Position Verification
Leverage the integrated magnet with DMSE electronic sensors to confirm end-of-stroke positions in automated setups.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX25-10S the Right Cylinder?
Choose this 200 mm bore when your application demands extreme thrust, such as 15708 N push at 0.5 MPa, but requires precise end-position tuning within a 15-25 mm window. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which may simplify your overall setup. The rear adjuster screw acts solely as a travel stop and cannot hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder, specify the 200 mm bore, 25 mm stroke, 10 mm adjustment, PT G3/4 ports, and the -S magnet.
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 SAIJ200BX25-10S 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 a maximum push force of 28274 N at 0.9 MPa.
The rear adjuster screw lets you mechanically shorten the effective travel from the 25 mm nominal stroke down to 15 mm. This creates a 15-25 mm usable window for fine-tuning the retract end-position at commissioning without adding external stops.
