About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X20-10
The AirTAC SAIJ80X20-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 2513N of push force at 0.5 MPa. By turning the external stopper screw, you can trim the effective travel down by up to 10 mm, creating a highly precise 10 to 20 mm usable stroke window. This allows you to fine-tune the end position at commissioning without swapping hardware.
The 25 mm carbon steel piston rod and M20x1.5 rod thread provide robust resistance against side loads, while the PT tapered port ensures a reliable pneumatic seal. As an extruded aluminum profile cylinder, it is dimensionally interchangeable per ISO 15552 and utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X20-10 Is Used
Precision Clamping
Dial in the exact 10 to 20 mm clamping distance on the fly to accommodate material thickness variations without changing the cylinder.
Machine Setup
Fine-tune the retract end position during commissioning to prevent over-travel and optimize the mechanical cycle of your equipment.
Product Changeover
Quickly adjust the stroke window by up to 10 mm when switching a production line to a new part size or format.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X20-10 the Right Cylinder?
Choose this 80 mm bore when an application demands high thrust in a very short travel distance, such as heavy clamping or pressing. If you need less force, stepping down to a 63 mm bore yields 1559N of push force at 0.5 MPa, whereas a 100 mm bore offers 3927N for heavier loads. The adjustable stroke is ideal for machine setups requiring variable end stops, but note that the rear adjuster functions only as a travel stop; it does not lock the load without live air. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80X20-10 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513N of push force and 2268N of pull force. It can achieve up to 4523N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 20 mm nominal stroke by up to 10 mm, resulting in a usable travel window between 10 and 20 mm. It is a stop, not a lock, so live air is still required to hold the load.
