About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX1000-40
The AirTAC SAIJ50X200-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 960-1000 mm usable travel window. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa, utilizing a 20 mm carbon steel rod with an M16x1.5 thread. The barrel is extruded aluminum with sensor grooves on both sides for straightforward positioning feedback.
This variant uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes PT tapered port threads (G1/4). The rear stopper screw allows you to fine-tune the retract end position during commissioning without adding external stops. The adjuster acts solely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX1000-40 Is Used
Product Changeovers
Dial in the 960 to 1000 mm travel window during line changeovers to accommodate different product lengths without physically swapping the cylinder.
Long-Stroke Indexing
Pushes or positions pallets along an extended conveyor section, using the rear stopper to fine-tune the exact resting position.
Commissioning Setup
Adjusts the retract end-stop precisely during machine commissioning to align tooling, preventing the need for machined spacer shims.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX1000-40 the Right Cylinder?
Choose this 50 mm bore when 40 mm bore thrust (628 N push at 0.5 MPa) is insufficient, but you want to avoid the larger 63 mm footprint (1559 N). The 40 mm adjustment range is ideal for product changeovers requiring variable end stops. For a fixed end position, the standard SAI cylinder is simpler. If the machine requires holding a load without live air, use a SAIL or BSAI cylinder instead of relying on this adjuster.
With a 1000 mm stroke, the unsupported 20 mm rod is susceptible to side-loading and sagging; an external guide rail is strongly recommended. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts (omitting FB, CA, CB, CR). It operates at 30-800 mm/s and uses PT ports.
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 SAIJ50 Adjustable Cylinder SAIJ50AX1000-40 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 200 kgf.
The rear adjuster screw lets you trim the effective travel back by up to 40 mm, creating a 960-1000 mm usable stroke window. It acts as a physical travel stop for end-position tuning and does not lock the load without live air.
