About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-75S
The AirTAC SAIJ80X200-75-S 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 75 mm. This yields a usable window of 125 to 200 mm, letting you dial in the exact retract position at commissioning without swapping out the unit. It delivers a robust 2513 N push force at 0.5 MPa and utilizes a PT tapered port thread.
Fitted with a magnet for position sensing, it supports AirTAC CMSE reed and DMSE electronic solid-state switches housed in the dual-side sensor grooves of the extruded aluminum barrel. The M20x1.5 piston rod provides high rigidity, but remember the rear adjuster acts purely as a mechanical stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-75S Is Used
Machine Setup Changeover
Quickly fine-tune the retract distance from 125 to 200 mm during product size changes on a packaging line without replacing the cylinder.
Variable End-Stop Forming
Dial in the exact end-of-stroke position for a pressing or forming application, using the 75 mm rear adjuster to accommodate material variances.
Adjustable Ejection Station
Eject parts at varying distances on a conveyor by adjusting the stroke window, utilizing the 2513 N push force to clear heavy components.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-75S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires high thrust (up to 2513 N at 0.5 MPa or 3518 N at 0.7 MPa) combined with flexible end-position tuning. If your setup needs less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa. The adjustable stroke is ideal for product changeovers, offering a variable end-stop rather than machining custom external stops. For load-holding without live pressure, choose the SAIL or BSAI series, as this adjuster is not a brake.
This model is dimensionally interchangeable with ISO 15552 cylinders, featuring a 200 mm stroke, 75 mm adjustment range, PT G3/8 port, and a -S magnet. It uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 200 mm, ensure proper guiding to prevent excessive side-loading on the M20x1.5 rod.
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 SAIJ80X200-75S FAQ
This 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 200 mm nominal stroke by up to 75 mm. This creates a usable travel window of 125 to 200 mm for fine-tuning end positions at commissioning.
