About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-30S
The AirTAC SAIJ80X65-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 65 mm nominal travel to a precise 35-65 mm usable window during commissioning. Delivering 2513 N of push force at 0.5 MPa, it handles demanding short-stroke tasks without needing external stops. This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE or DMSE sensor integration.
Because the rear screw acts purely as a travel stop and the standard air cushions manage end-of-stroke deceleration, this cylinder cannot hold a load without live air pressure. For positive load-holding, you would need an external rod lock or a related SAIL pneumatic lock cylinder. The extruded aluminum barrel provides standard ISO 15552 mounting interchangeability.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-30S Is Used
Product Changeover
Quickly fine-tune the 35-65 mm travel window when switching between part sizes on a packaging line, using the rear adjuster instead of re-mounting hardware.
Clamping Force Setup
Leverage the 2513 N push force to secure heavy workpieces, dialing in the exact clamping position at commissioning without over-stroking the mechanism.
Sensor-Driven Positioning
Utilize the integrated magnet with DMSE solid-state sensors to confirm the adjusted end-stop position in automated assembly fixtures.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX65-30S the Right Cylinder?
Choose this 80 mm bore when a 50 mm cylinder's 982 N push force at 0.5 MPa is insufficient, but a 100 mm bore (3927 N) would be physically oversized for your machine. The 30 mm adjustment range is ideal for product changeovers where the exact end-of-stroke position must be fine-tuned on the fly, avoiding the need to swap out a fixed-stroke SAI cylinder. To match this exact ISO 15552 replacement, specify the 80 mm bore, 65 mm stroke, 30 mm adjuster, PT tapered port threads, and the -S magnet option.
Although the 65 mm stroke is relatively short, the robust 25 mm rod diameter handles moderate side loads effectively. Always ensure your mounting choice—whether Basic, FA, LB, TC, FTC, TCM1, or TCM2—properly supports the load to prevent binding, as the SAIJ series omits FB, CA, CB, and CR mounts.

- ✓ 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 SAIJ80BX65-30S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At a maximum 1.0 MPa, the push force reaches 513 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 65 mm nominal stroke by up to 30 mm. This creates a usable travel window of 35 to 65 mm for precise end-position tuning without replacing the cylinder.
