About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX800-10S
The AirTAC SAIJ50X800-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a 790 to 800 mm usable travel window for precise end-position tuning. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa, making it well-suited for moderate-load automation. The integrated -S magnet enables direct position sensing with AirTAC CMSE reed or DMSE electronic switches.
This model features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads with a G1/4 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts strictly as a travel stop to dial in the 10 mm trim range, not a load-holding lock; for dead-air position holding, consider an external pilot-operated check valve or the SAIL lock variant.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX800-10S Is Used
Long-Stroke Material Handling
Drives extended transfer carriages on packaging lines, using the 10 mm rear stopper to fine-tune the exact 790-800 mm hand-off position without adding external bumpers.
Product Changeover Adjustment
Allows operators to quickly dial in the end-of-stroke position during format size changes on a conveyor, saving commissioning time versus fixed-stroke alternatives.
Corrosive Environment Actuation
The SUS304 stainless steel rod provides excellent moisture and chemical resistance for washdown manufacturing areas while maintaining standard ISO 15552 mounting dimensions.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX800-10S the Right Cylinder?
Select this 50 mm bore when an application requires approximately 982 N of thrust at 0.5 MPa, bridging the gap between the 40 mm (628 N) and 63 mm (1559 N) bore sizes. An adjustable stroke is ideal for machine setups requiring on-the-fly end-stop calibration without swapping out the entire cylinder. To match this ISO 15552 replacement exactly, specify: 50 mm bore, 800 mm stroke, 10 mm adjustment, PT port threads, SUS304 rod, and the -S magnet.
Because this cylinder features a long 800 mm stroke, the 20 mm diameter rod will experience amplified leverage forces under any side loading. An external guide rail should be installed to prevent rod binding and premature seal wear. Remember that the rear stopper and air cushions only decelerate the load; they do not function as a brake, so a SAIL or BSAI locking cylinder is required if mechanical load holding is necessary.
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 SAIJ50BX800-10S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If higher pressure is available, it can deliver up to 1374 N of push force at 0.7 MPa.
The rear adjusting screw acts as a mechanical stopper that allows you to trim the effective stroke back by up to 10 mm, creating a 790 to 800 mm usable travel window. It is designed for fine-tuning end positions at commissioning and does not lock the load in place without air pressure.
