About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-75
The AirTAC SAIJ80X160-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the effective travel down from 160 mm to a minimum of 85 mm. Delivering a substantial 4523 N of push force at 0.9 MPa, it handles heavy-duty positioning with ease. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This adjustable variant uses a 25 mm carbon steel piston rod and an M20x1.5 rod thread, providing excellent rigidity and side-load resistance. The rear adjuster acts purely as a mechanical stop to set the retraction end position during commissioning or product changeover, meaning it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-75 Is Used
Product Changeover
Dial in the 85-160 mm stroke window during line changeovers to accommodate different package lengths without replacing the actuator.
End-Stop Calibration
Fine-tune the retract position during initial machine commissioning, preventing hard mechanical crashes by precisely setting the travel limit.
Variable Diverter Arm
Adjust the stroke on-site to alter the reach of a sorting diverter arm as belt speeds or product dimensions shift.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-75 the Right Cylinder?
Choose this 80 mm bore if your application requires thrust between the 2805 N produced by a 63 mm cylinder and the 7068 N available from a 100 mm bore at 0.9 MPa. The 75 mm adjustment range is particularly useful when a machine must accommodate multiple product sizes without physically swapping cylinders, allowing operators to dial in the exact 85-160 mm travel window on the fly. When ordering an ISO 15552 replacement, confirm the 160 mm stroke, 75 mm adjuster, PT tapered G3/8 port, and your required mounting bracket from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ80X160-75 FAQ
The rear adjuster screw lets you shorten the 160 mm nominal stroke by up to 75 mm, creating a usable travel window of 85 to 160 mm. It functions as a mechanical stop for end-position tuning and is not a lock; it will not hold the load without continuous air pressure.
At 0.9 MPa, the SAIJ80X160-75 generates 4523 N of push force and 2268 N of pull force. At a standard 0.5 MPa, it provides 2513 N push and 2268 N pull.
