About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-100S
The AirTAC SAIJ80X170-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position without swapping hardware. With a nominal 170 mm stroke and a 100 mm adjustment range, this model provides a highly flexible usable travel window of 70 to 170 mm. It delivers a robust 2513 N of push force at 0.5 MPa, making it well-suited for medium-to-heavy actuation tasks.
This unit includes a standard carbon steel piston rod and a PT tapered port thread. Equipped with a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed in the dual-side extruded aluminum barrel grooves. The rear adjuster acts purely as a travel stop for commissioning flexibility and does not lock the load in place without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-100S Is Used
Variable Product Changeover
Ideal for packaging lines processing different carton sizes, allowing operators to dial back the stroke from 170 mm down to 70 mm to accommodate varying package depths without changing cylinders.
Machine Setup Calibration
Perfect for dialing in exact end-of-stroke positions during commissioning, ensuring precise mechanical stops are met before finalizing the pneumatic setup.
Adjustable Ejector Station
Provides adaptable ejection force on an assembly line, letting maintenance fine-tune the retract distance to match varying product widths on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-100S the Right Cylinder?
Choose this SAIJ80X170-100-S when your application requires frequent product changeovers or variable end-stop positioning within a 70 to 170 mm travel window. If your process needs less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, whereas moving up to a 100 mm bore provides 3927 N for heavier loads. The integrated magnet allows precise end-of-stroke detection using CMSE or DMSE switches without external brackets.
For an ISO 15552 replacement match, ensure the target cylinder shares the 80 mm bore, 170 mm nominal stroke, G3/8 port, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR variants. Remember that the rear adjuster and air cushions only decelerate the stroke; they do not hold the load pneumatically. For fail-safe load holding without live air, consider an external pilot-operated check valve or the AirTAC SAIL or BSAI series.
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 SAIJ80X170-100S FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 3518 N.
It has a 170 mm nominal stroke with a 100 mm rear adjustment screw, creating a usable travel window of 70 to 170 mm. The rear screw acts as a stop to fine-tune the end position, but it does not lock the load without continuous air pressure.
