Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-30
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-30
The AirTAC SAIJ80X1000-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 970 to 1000 mm usable travel window, allowing you to dial back the stroke by up to 30 mm during commissioning. With a 25 mm carbon steel rod and an M20x1.5 thread, it handles high side loads well, though a 1000 mm stroke still requires an external guide to prevent rod sag. It delivers 2513 N of push force at 0.5 MPa.
This model uses a PT tapered port thread and operates at speeds of 30-800 mm/s. The rear adjuster acts purely as a mechanical stop for end-position tuning; it does not hold the load without live air. For position holding, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, though a magnet is not included in this configuration.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-30 Is Used
Machine Changeover
Fine-tune the 970-1000 mm travel window during product size changes without swapping cylinders or adding external stopper blocks.
Variable End-Stop Positioning
Dial in the exact retract position on long-stroke material handling lines using the 30 mm rear adjustment screw.
Assembly Line Tuning
Achieve precise end-position tuning at commissioning to accommodate mechanical tolerance variations across long-stroke actuators.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-30 the Right Cylinder?
Choose this 80 mm bore when you need 2513 N of thrust at 0.5 MPa, stepping up from a 63 mm bore that offers 1559 N. The adjustable 30 mm window is ideal for product changeovers where exact end-positioning varies, eliminating the need to swap out a fixed-stroke SAI cylinder. When matching ISO 15552 replacements, verify the 1000 mm stroke, 30 mm adjustment, PT port thread, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke exceeds 300 mm, always use an external guide to manage side-load forces. The rod and air cushion only decelerate the travel end; they do not lock the load.
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 SAIJ80X1000-30 FAQ
It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw lets you shorten the effective travel from 1000 mm down to 970 mm. It acts as a mechanical stop for fine-tuning and does not lock the load without live air pressure.
