About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-20
The AirTAC SAIJ80X1000-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 980-1000 mm without adding external stops. Equipped with a 25 mm piston rod and PT tapered port threads, it delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa. The extended 1000 mm stroke operates at speeds of 30-800 mm/s and relies on adjustable air cushions at both ends to decelerate the payload.
This specific SKU utilizes a SUS304 stainless steel rod for superior corrosion resistance and includes dual sensor grooves on the extruded aluminum barrel. The rear adjustment screw acts purely as a mechanical travel stop for commissioning and product changeovers. It does not lock or hold the load without continuous air pressure; for true fail-safe load holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-20 Is Used
Machine Setup & Changeover
Dial in the exact 980 to 1000 mm end-position during line changeovers without physically replacing the cylinder or bolting on external stopper blocks.
Variable End Stops
Adjust the retract distance on the fly to accommodate different package sizes or pusher lengths on long-stroke material handling conveyors.
Long-Stroke Positioning
Leverage the 2513 N push force to move heavy pallets or fixtures over a 1000 mm travel path while using the rear screw for final alignment tuning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-20 the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust—stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N, while stepping up to a 100 mm bore yields 3927 N. An adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, saving the cost of swapping a fixed-stroke SAI cylinder. When replacing an ISO 15552 unit, match the 80 mm bore, 1000 mm stroke, 20 mm adjustment range, PT G3/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the stroke is 1000 mm, the unsupported length of the 25 mm rod makes the assembly highly susceptible to side-loading. An external guide rail is strongly recommended to prevent binding and premature seal wear. Furthermore, the rear adjuster and air cushions only manage end-of-stroke deceleration; they cannot hold a load statically without live air pressure.
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 SAIJ80 Adjustable Cylinder SAIJ80BX1000-20 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to mechanically shorten the nominal 1000 mm stroke by up to 20 mm, creating a usable travel window of 980-1000 mm. This screw acts as a travel stop for fine-tuning end positions and does not lock the load without continuous air pressure.
