About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X35-30S
The AirTAC SAIJ80X35-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 2513N of push force at 0.5 MPa and uses a PT tapered G3/8 port. Because this specific SKU carries a 30mm adjustment code on a 35mm nominal stroke, you can dial back the effective travel to establish a precise 5-35mm usable window during commissioning.
This rear stopper lets you fine-tune the end position without swapping the barrel or adding external stops. The extruded aluminum body includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, enabled by the -S magnet. The M20x1.5 carbon steel rod provides high side-load resistance, while the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omits FB, CA, CB, and CR.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X35-30S Is Used
Short-Stroke Clamping
Dial in the 5-35mm travel window to precisely set clamping force on varying part sizes without changing the cylinder.
Machine Setup Tuning
Fine-tune the retract end position during commissioning to perfect a short ejection stroke, avoiding external stop hardware.
Product Changeover
Quickly adjust the effective stroke on packaging lines when switching between different product profiles.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X35-30S the Right Cylinder?
Choose this 80mm bore when 50mm (982N at 0.5 MPa) is too weak and 100mm (3927N) is overkill. An adjustable stroke is ideal for machine setups requiring a variable end-stop to dial in a short clamping distance, unlike a fixed SAI cylinder. Remember the rear adjuster acts as a travel stop, not a lock; it will not hold the load without live air. For load-holding without pressure, select SAIL or BSAI. This SKU matches ISO 15552 mounting dimensions with a PT port and -S magnet.

- ✓ 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 SAIJ80X35-30S FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It operates at speeds up to 800 mm/s.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 30mm. This creates a usable 5-35mm travel window for fine-tuning without replacing the cylinder.
