About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-50
The AirTAC SAIJ80X110-50 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 2513N push force at 0.5MPa and uses a G3/8 port. The integrated rear stopper allows you to fine-tune the effective travel down from the 110mm nominal stroke, creating a highly versatile 60 to 110mm usable window for precise end-position tuning during machine commissioning.
This 50mm adjustment range is engineered for rapid product changeovers, letting you shift the retract stop without physically swapping the cylinder or adding external stops. The extruded aluminum barrel features sensor grooves on both sides for CMSE reed and DMSE electronic switches. The carbon steel rod with its M20x1.5 thread offers excellent side-load resilience, while the adjustable air cushions at both ends manage deceleration. Note that this rear adjuster acts strictly as a travel stop, not a load-holding lock.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-50 Is Used
Product Changeover Setup
Dial in the 60-110mm travel window during packaging line format changes to accommodate different carton sizes without swapping hardware.
Variable End-Stop Positioning
Fine-tune the retract position precisely during machine commissioning to perfect the timing of a pressing or clamping operation.
Assembly Line Calibration
Adjust the rear stopper on the fly to synchronize multiple actuators on an automated assembly line without external shims.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-50 the Right Cylinder?
Choose this SAIJ80X110-50 when your application requires a 60-110mm stroke window and approximately 2513N of thrust at 0.5MPa. If your force requirements are lower, stepping down to a 63mm bore yields 1559N; if you need more power, a 100mm bore provides 3927N. The adjustable rear stop is ideal for setups needing variable end-stops, whereas a fixed SAI cylinder is better for dedicated unchanging strokes. For holding loads safely without live air pressure, select a SAIL or BSAI cylinder instead, as this adjuster does not lock the load.
When replacing an ISO 15552 cylinder, match the 80mm bore, 110mm nominal stroke, 50mm adjustment, PT tapered port thread, and your required mounting bracket (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because this unit features an 80mm bore and a 110mm stroke, always verify your mechanical guide supports to handle potential side loads, despite the robust 25mm rod diameter.
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 SAIJ80X110-50 FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It operates at speeds between 30 and 800mm/s.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke from the 110mm nominal length by up to 50mm, providing a usable travel window of 60 to 110mm. It functions as a travel stop only, not a lock.
