About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-40
The AirTAC SAIJ80X60-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the 60 mm nominal travel by up to 40 mm. This creates a highly versatile 20-60 mm usable stroke window, perfect for dialing in exact end positions during machine commissioning without swapping out the physical actuator. It delivers robust thrust, generating 2513 N of push force and 2268 N of pull force at a 0.5 MPa operating pressure.
This specific SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, alongside PT tapered port threading (G3/8). The extruded aluminum barrel features sensor grooves on both sides for future integration of CMSE reed or DMSE solid-state switches if position feedback is later required. The rear adjuster acts strictly as a mechanical stop to set the travel end, meaning it does not lock or hold the load without continuous air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-40 Is Used
Product Changeover Dials
Quickly modify the effective travel from 20 to 60 mm when switching between product sizes on a packaging line, using the rear screw to set new end positions without changing the cylinder.
Commissioning End-Tuning
Fine-tune the exact retraction point during machine setup to avoid crushing delicate workpieces, relying on the 40 mm adjustment range to perfect the cycle.
Variable End-Stop Forming
Adjust the stroke end externally on the fly for light assembly or forming operations where material thickness varies, preventing the need for hard mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-40 the Right Cylinder?
Choose this 80 mm bore actuator when an application demands high force within a compact, variable end-stop range. If you need slightly less thrust, stepping down to a 63 mm bore yields 1559 N of push force at 0.5 MPa, whereas moving up to a 100 mm bore provides 3927 N. The adjustable rear stopper is ideal for product-size changeovers on a line, allowing operators to fine-tune the 20-60 mm travel window on the fly instead of installing fixed external stops or reverting to a standard SAI cylinder.
Because this is a double-acting cylinder, the rear adjuster and variable air cushions only decelerate the stroke end; they cannot hold a load safely without live air. For true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series instead. When matching ISO 15552 interchangeable replacements, verify the 80 mm bore, 60 mm stroke, 40 mm adjustment range, PT G3/8 port, and your required mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2).

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 SAIJ80AX60-40 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 need higher force, the 100 mm bore version offers 3927 N of push force at the same pressure.
The rear adjusting screw acts as a mechanical stop that trims the 60 mm nominal stroke back by up to 40 mm, giving you a usable travel window of 20 to 60 mm. It sets the end position but does not lock the load without continuous air pressure.
