About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-100
The AirTAC SAIJ80X165-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5MPa, utilizing a 25mm carbon steel piston rod and G3/8 PT ports. By integrating an external 100mm adjustment screw, this model creates a usable travel window between 65 and 165mm, enabling exact end-position tuning without swapping out the entire actuator.
The rear stopper mechanism allows technicians to dial in the retract position directly during commissioning or product changeover. While the adjuster and variable air cushions at both ends decelerate the load effectively, neither component functions as a lock; the cylinder requires live air to maintain its position. This extruded aluminum barrel features dual sensor grooves for CMSE or DMSE switches, though this specific SKU is configured without a magnet.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-100 Is Used
Variable End-Stop Positioning
Ideal for automated lines processing different material lengths, allowing operators to dial back the stroke from 165mm down to 65mm via the rear screw without changing the physical cylinder mount.
Pressing Force Calibration
Provides 2513N of thrust at 0.5MPa for assembly presses, where the exact bottoming-out position must be fine-tuned on the fly to prevent damage to delicate components.
Machine Format Changeover
Speeds up equipment reconfigurations for new product runs by offering a wide 100mm adjustment range, replacing the need to physically swap out fixed-stroke actuators.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-100 the Right Cylinder?
Select this 80mm bore actuator when an application demands high thrust combined with variable end stops, such as pressing or clamping stations that process multiple part sizes. If the 2513N push force at 0.5MPa exceeds your requirement, stepping down to the 63mm bore yields 1559N; conversely, upgrading to the 100mm bore provides 3927N. The generous 100mm adjustment window makes the SAIJ80X165-100 highly versatile for machine setups requiring frequent format changes.
For an exact ISO 15552 replacement, match the 80mm bore, 165mm nominal stroke, 100mm adjuster code, G3/8 PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. Because the 25mm rod handles side loads well but cannot support unsupported travel alone, always incorporate an external guide for this 165mm stroke. If the machine requires true load-holding without continuous air pressure, utilize an AirTAC SAIL or BSAI cylinder instead of relying on the adjuster.

- ✓ 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 SAIJ80X165-100 FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. If operated at 0.7MPa, the push force increases to 3518N.
The rear adjuster acts as an external stopper that lets you trim the effective travel back by up to 100mm. This creates a usable stroke window of 65 to 165mm, allowing you to set the exact retract end-position during commissioning without adding external stops.
