About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X30-10S
The AirTAC SAIJ80X30-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal 30 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 20-30 mm for precise end-position tuning. It delivers 2513 N of push force at 0.5 MPa and reaches speeds up to 800 mm/s. The carbon steel rod and M20x1.5 thread provide robust side-load resistance, while the extruded aluminum barrel includes sensor grooves on both sides.
This -S variant includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position without adding external stops. It uses a PT tapered port and supports the SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X30-10S Is Used
Machine Setup Tuning
Dial in the exact 20-30 mm retract position during commissioning to perfect a clamping motion without machining external stopper blocks.
Product Changeover
Quickly adjust the stroke end-stop by up to 10 mm when switching the production line to a slightly different product size.
High-Force Positioning
Leverage the 2513 N push force at 0.5 MPa for firm pressing or holding, using the rear screw to set the precise travel limit.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X30-10S the Right Cylinder?
Choose this 80 mm bore when you need higher thrust than a 63 mm cylinder (which provides 1559 N at 0.5 MPa) but want to avoid the larger 100 mm footprint. The adjustable stroke is ideal for machine setup and product changeover, allowing you to dial in the exact end-stop without swapping the cylinder. For holding loads without live air pressure, select a SAIL or BSAI lock cylinder instead, as the SAIJ adjuster is a travel stop, not a brake. Ensure your ISO 15552 replacement matches the 80 mm bore, 30 mm stroke, PT port, and -S magnet.

- ✓ 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 SAIJ80X30-10S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. It can deliver up to 4523 N push at 0.9 MPa.
The nominal stroke is 30 mm, but the rear adjuster allows you to shorten the effective travel by up to 10 mm. This creates an adjustable 20-30 mm stroke window for fine-tuning the end position.
