About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X15-10
The AirTAC SAIJ80X15-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 5 to 15 mm. Part of the SAIJ adjustable-stroke family, it allows technicians to dial in the exact end position during commissioning without adding external stops. This 80 mm bore generates 2513 N of push force at 0.5 MPa and uses a robust 25 mm carbon steel rod with an M20x1.5 thread to handle high side loads.
It features variable air cushions at both ends and a tapered PT G3/8 port. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE or DMSE switches for position feedback. The rear adjuster acts purely as a mechanical stop for deceleration and positioning, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X15-10 Is Used
Short-Stroke Clamping
Provides a 5-15 mm travel window for clamping parts precisely during machining, allowing operators to fine-tune the grip without relocating physical stoppers.
Product Changeovers
Ideal for packaging lines where varying product sizes require quick end-position adjustments, using the rear screw to adapt the stroke on the fly.
Machine Setup
Used in automated assembly stations to dial in the exact retracted position during initial commissioning, ensuring perfect alignment without external spacers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X15-10 the Right Cylinder?
Choose this 80 mm bore when an application requires substantial force but only a very short, highly precise travel window. If you need less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, while moving up to a 100 mm bore provides 3927 N for heavier fixtures. The adjustable stroke is ideal for setups requiring frequent product changeovers or exact end-position tuning that a fixed-stroke SAI cylinder cannot provide.
For load-holding without continuous air pressure, this cylinder is insufficient since the rear adjuster is a stop, not a lock; you would need an SAIL or BSAI variant instead. To replace this ISO 15552 cylinder exactly, match the 80 mm bore, 15 mm stroke, 10 mm adjustment, PT G3/8 port, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting options.
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 SAIJ80X15-10 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjusting screw allows you to shorten the nominal 15 mm stroke by up to 10 mm, creating a usable travel window of 5 to 15 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
