About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-100
The AirTAC SAIJ80X180-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a highly flexible 80-180 mm usable stroke window, enabling precise end-position tuning at commissioning without swapping out the entire cylinder. In the 80 mm bore class, it delivers a robust 2513 N pull force at 0.5 MPa and utilizes a G3/8 port for pneumatic supply.
The carbon steel piston rod features an M20x1.5 thread, providing a durable interface for mounting attachments. As an extruded aluminum profile cylinder, it includes sensor grooves on both sides for CMSE reed or DMSE electronic solid-state switches. It uses variable air cushions at both ends to decelerate the load, but the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-100 Is Used
Product Changeover
Dial in the 80-180 mm travel window on packaging lines when switching to a different carton size, using the rear stopper to fine-tune the retract distance rapidly.
Machine Setup
Trim the stroke during initial commissioning to perfect the end-position without machining custom spacer blocks or changing the cylinder's physical mounting.
Variable End Stops
Adjust the effective stroke dynamically for assembly processes that require testing multiple extend distances on the same fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-100 the Right Cylinder?
Choose this 80 mm bore when your application requires substantial force (up to 2513 N pull at 0.5 MPa) alongside a highly variable end-stop. If you need less force, stepping down to a 63 mm bore yields 1402 N pull, while moving up to a 100 mm bore provides 3681 N pull. The 100 mm adjustment range is ideal for machines handling frequent product-size changeovers, replacing the need to bolt on external physical stops. For load-holding without live air, this cylinder is not a lock; you would need to specify a SAIL (air-released lock) or BSAI (clamp-lock) variant instead.
When matching an ISO 15552 replacement, verify the 80 mm bore, 180 mm nominal stroke, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this specific SKU has a 180 mm stroke, it falls under the 30-800 mm/s standard speed range and does not strictly require external guiding for side loads, though the M20x1.5 rod handles standard side-loading well.

- ✓ 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 SAIJ80X180-100 FAQ
The rear adjuster acts as an external mechanical stop that lets you shorten the 180 mm nominal stroke by up to 100 mm, creating a usable travel window of 80 to 180 mm. It sets the end-position but does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ80X180-100 provides 2513 N of pull force and 3518 N of push force. It can deliver a maximum push force of 4523 N at 0.9 MPa.
