About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-10
The AirTAC SAIJ80X190-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 180 to 190 mm usable travel window, allowing you to trim the effective stroke by up to 10 mm during commissioning without swapping out the entire unit. Built with an extruded aluminum barrel, it delivers robust thrust, pushing 4523 N at 0.9 MPa and pulling 2268 N at 0.5 MPa.
This 80 mm bore actuator uses a G3/8 port and a 25 mm carbon steel rod with an M20x1.5 thread, providing substantial side-load resistance for industrial handling. The rear stopper sets the retract end position, but it acts purely as a travel stop and does not hold the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-10 Is Used
Machine Setup Calibration
Dial in the exact 180 to 190 mm end position during initial commissioning to perfect part ejection without adding external mechanical stops.
Product Changeover
Quickly trim the stroke by up to 10 mm on a packaging line when switching to a slightly shorter carton format.
High-Force Forming
Leverage the 4523 N push force at 0.9 MPa for pressing operations while fine-tuning the bottom dead center for material thickness variations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-10 the Right Cylinder?
Choose this 80 mm bore when an application demands high thrust but requires micro-adjustments to the end-stop; if you need less force, stepping down to a 63 mm bore yields 2805 N push at 0.9 MPa. The 10 mm adjustment window is ideal for dialing in exact positions during machine setup or product changeovers, avoiding the need to bolt on external stops. For dead-end positioning, remember the adjuster is a stop, not a lock, so load-holding without live air requires a SAIL or BSAI variant.
To match this exact ISO 15552 dimensionally interchangeable replacement, confirm an 80 mm bore, 190 mm stroke, 10 mm adjustment range, PT tapered port threads, and standard carbon steel rod material. Because this unit lacks a magnet, it does not support CMSE or DMSE sensors without modification.
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 SAIJ80X190-10 FAQ
At 0.9 MPa operating pressure, this 80 mm bore cylinder provides a push force of 4523 N and a pull force of 3681 N. It reaches a maximum thrust of 513 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 190 mm nominal stroke anywhere down to 180 mm. It only sets the travel end and does not lock the load without continuous air pressure.
