About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-50
The AirTAC SAIJ80X1000-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 950 mm from a 1000 mm nominal stroke. It delivers a robust 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it suitable for heavy actuation tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning of CMSE reed or DMSE solid-state switches.
This configuration uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The 25 mm rod diameter and M20x1.5 thread provide excellent rigidity, but at 1000 mm of stroke, an external guide is highly recommended to manage side loads. The rear adjuster acts solely as a travel stop for commissioning and product changeovers, not as a lock.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-50 Is Used
Format Changeovers
Dial in the exact 950 to 1000 mm end-position during product line size transitions without changing the cylinder.
Long-Stroke Pushing
Utilize the 2513 N push force at 0.5 MPa to move heavy pallets or workpieces across a 1 meter travel distance.
Washdown Actuation
Leverage the SUS304 stainless steel rod for reliable performance in corrosive or high-moisture manufacturing environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-50 the Right Cylinder?
Choose this 80 mm bore when the 50 mm bore class (982 N push at 0.5 MPa) is insufficient for your tooling weight. The 50 mm rear adjustment range is ideal for machinery requiring variable end-stops during format or product size changes, eliminating the need to physically swap cylinders or bolt on external stops. Because this is a long 1000 mm stroke, you must support the load with an external linear guide to prevent rod binding.
For dimensionally interchangeable ISO 15552 replacements, match the 80 mm bore, 1000 mm stroke, 50 mm adjustment, G3/8 PT ports, and SUS304 rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your application requires holding the load without live air pressure, note that the rear adjuster is only a stop; you must use an SAIL pneumatic lock, BSAI clamp-lock, or external rod lock instead.
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 SAIJ80BX1000-50 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjusting screw acts as an external stopper, allowing you to shorten the effective travel from 1000 mm down to 950 mm. This provides a 50 mm tuning window for end-position setup without replacing the cylinder.
