About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X155-75
The AirTAC SAIJ80X155-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 155 mm stroke and a 75 mm adjustment range, it provides a wide usable travel window of 80 to 155 mm. This allows you to dial in the exact retract end-position during commissioning without swapping out the barrel. It delivers robust performance, generating 2513 N of push force and 2268 N of pull force at 0.5 MPa.
Equipped with a 25 mm carbon steel rod and an M20x1.5 thread, it handles substantial side loads, though long unsupported strokes still require external guide rails. The extruded aluminum barrel includes sensor grooves on both sides for fitting CMSE reed or DMSE electronic switches if needed. This adjustable model utilizes a focused mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X155-75 Is Used
Variable End-Stop Positioning
Ideal for assembly stations that need to change the retract distance on the fly, utilizing the 80-155 mm travel window to accommodate different part heights without changing cylinders.
Machine Changeover
Speeds up product line changeovers by allowing operators to fine-tune the end position via the rear screw rather than adding physical external spacers or stops.
Stroke Tuning
Perfect for dialing in the exact clamping or pressing distance during commissioning, ensuring the 4523 N push force at 0.9 MPa is applied at the precise required point.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X155-75 the Right Cylinder?
Choose this 80 mm bore when your application requires more thrust than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but does not need the full 3927 N push capacity of a 100 mm bore. The extensive 75 mm adjustment range is ideal for machinery that frequently handles multiple product sizes, acting as a variable end-stop. Remember that the rear adjuster is strictly a travel stop, not a locking device; it cannot hold a load without continuous air pressure. For true fail-safe load holding, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 155 mm stroke, 75 mm adjustment, PT tapered port thread, and mounting interface. Because the 155 mm stroke is under the 300 mm threshold, standard side-loading concerns are minimized, but the 25 mm rod still provides excellent rigidity for standard dynamics.

- ✓ 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 SAIJ80X155-75 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 75 mm. This creates a usable travel window between 80 and 155 mm, allowing precise retract end-position tuning without replacing the cylinder.
At 0.5 MPa operating pressure, it provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 4523 N.
