About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX155-75
The AirTAC SAIJ200X155-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 80-155 mm from its 155 mm nominal stroke. Built with a SUS304 stainless steel rod and a PT tapered port, it delivers a substantial 15708 N push force at 0.5 MPa and safely operates within a 30-500 mm/s speed range. The extruded aluminum barrel features sensor grooves on both sides for straightforward position feedback.
This adjustable-stroke variant allows operators to fine-tune the retract end position during commissioning or product changeovers without adding external stops. The rear adjuster acts purely as a mechanical travel stop to set the end-of-stroke deceleration alongside the standard air cushions; it is not a lock and cannot hold a load without live air pressure. For load-holding requirements without continuous pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX155-75 Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 80-155 mm window during machine commissioning to perfect a pressing operation without swapping cylinders.
Product Changeover
Quickly adapt the stroke length on a packaging line when processing different sized heavy materials requiring up to 15708 N of push force.
Heavy Assembly Press
Leverage the 200 mm bore thrust to seat large components, using the rear stopper to prevent over-travel and ensure consistent joint closure.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX155-75 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires massive thrust, such as 15708 N push or 15080 N pull at 0.5 MPa, combined with a variable end-stop. The 75 mm adjustment range is ideal for setups requiring frequent product-size changeovers on a line. If you need less force, stepping down to a 160 mm bore yields 10053 N push at 0.5 MPa. Unlike a fixed-stroke SAI cylinder, the SAIJ rear screw mechanism lets you dial in the exact travel limit on the fly.
Because the 155 mm stroke falls below the 300 mm threshold, side-load risks are moderate, but the robust 40 mm rod and M36x2 thread handle significant off-center loads. The mounting interface is dimensionally interchangeable per ISO 15552, utilizing a reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR brackets. This specific configuration includes a PT port thread and a SUS304 stainless steel rod, but lacks a piston magnet, meaning it is not compatible with CMSE or DMSE sensors without modification.
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 SAIJ200BX155-75 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that can shorten the 155 mm nominal stroke by up to 75 mm, creating an 80-155 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
