About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-100
The AirTAC SAIJ80X115-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits on-the-fly end-position tuning. With a nominal 115 mm stroke and a 100 mm adjustment range, it provides a wide usable travel window of 15 to 115 mm. This flexibility allows you to dial in the exact retract distance during commissioning without swapping hardware or adding external stops. The 80 mm bore delivers 2513 N of push force at 0.5 MPa, scaling up to 4523 N at 0.9 MPa, making it well-suited for heavier positioning tasks.
This model features a carbon steel piston rod with an M20x1.5 thread, providing a robust interface that handles side loads better than smaller variants. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches, though this specific SKU is configured without a magnet. It uses a PT G3/8 port and offers variable air cushioning at both ends to manage deceleration across its 30-800 mm/s speed range.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-100 Is Used
Variable Product Changeover
Quickly reconfigure the retract distance from 15 to 115 mm on packaging lines handling different carton sizes without changing the cylinder.
Machine Setup Calibration
Fine-tune the end-stop position during initial commissioning to perfectly time a heavy 2513 N pressing or forming action.
Adjustable End-Positioning
Use the rear screw to set precise lower limits for assembly presses, allowing operators to adjust the depth without adding external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-100 the Right Cylinder?
Choose this 80 mm bore when your application requires substantial force—stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N, while stepping up to a 100 mm bore increases it to 3927 N. The massive 100 mm adjustment range is ideal for machines processing varying product sizes, acting as a variable end-stop that replaces complex mechanical shimming. Because the nominal stroke is under 300 mm, external side-load guides are less critical here than on longer units, though the 25 mm rod still benefits from a linear guide for optimal seal life.
When specifying a replacement, match the 80 mm bore, 115 mm nominal stroke, 100 mm adjustment code, PT G3/8 port, and carbon steel rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets. Remember that the rear adjuster is a travel stop, not a locking device; this cylinder cannot hold a load without live air pressure, so integrate a SAIL or BSAI cylinder if fail-safe holding is required.

- ✓ 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 SAIJ80X115-100 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw allows you to reduce the effective stroke by up to 100 mm from the 115 mm nominal length, creating a usable travel window of 15 to 115 mm. It acts purely as a travel stop and does not lock the load without continuous air pressure.
