About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX350-10
The AirTAC SAIJ200X350-10 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa and pulling 15080N at 0.5 MPa. The integrated adjustment screw allows you to trim the nominal 350 mm travel back by up to 10 mm, creating a precise 340-350 mm operational window for exact end-position calibration.
Built for harsh environments, this variant uses a SUS304 stainless steel rod (option B) for superior corrosion resistance. It features a G3/4 PT tapered port and dual-side sensor grooves. Note that the rear stopper and variable air cushions only decelerate the load; they do not function as a mechanical lock. For true load-holding without live air pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX350-10 Is Used
Heavy Press Tuning
Dial in the exact 340-350 mm end-of-stroke position during machine commissioning to ensure perfect pressing force without machining new spacers.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm on a packaging line when transitioning between slightly different heavy product sizes.
Long-Stroke Alignment
Fine-tune the extended position of heavy lifting fixtures on a 350 mm stroke actuator to perfectly align large components before clamping.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX350-10 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application demands maximum force within a standard ISO 15552 mounting footprint. If you need less thrust, stepping down to a 160 mm bore yields 9425N pull at 0.5 MPa, whereas this 200 mm bore provides 15080N. The 10 mm adjustable range is specifically useful for final commissioning tweaks or minor product changeovers, avoiding the need to physically swap cylinders or add external stop blocks.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 350 mm stroke, G3/4 PT port, and the chosen mounting accessory from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 350 mm, the long unsupported piston rod requires an external guide to prevent excessive side-loading and premature seal wear. This unit lacks a magnet, so position sensing requires external switches rather than embedded CMSE or DMSE sensors.
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 SAIJ200BX350-10 FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder generates a push force of 28274N and a pull force of 22612N. At 0.5 MPa, it provides 15708N push and 15080N pull.
A rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 350 mm nominal stroke by up to 10 mm, resulting in a usable travel window of 340-350 mm. This stopper only sets the end position and does not lock the load without live air pressure.
