About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-30S
The AirTAC SAIJ100X30-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 0-30 mm, allowing you to fine-tune the retract end-position during commissioning without adding external stops. The 100 mm bore generates 3927 N of push force at 0.5 MPa, making it suited for heavy pressing and holding tasks.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE reed and DMSE electronic sensors. It uses a PT tapered G1/2 port and retains the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-30S Is Used
Product Changeover
Dial in the 0-30 mm retract window to switch between varying package sizes on a packaging line without swapping hardware.
Press Fit Tuning
Leverage the 3927 N push force and rear stopper to set precise end-of-travel limits for light assembly operations.
Machine Setup
Use the rear adjuster during commissioning to establish exact end positions instantly, avoiding external stopper brackets.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-30S the Right Cylinder?
Select this 100 mm bore when an 80 mm bore (2513 N push at 0.5 MPa) lacks the necessary thrust. An adjustable stroke is chosen over a fixed SAI when a machine requires variable end-stops for rapid product-size changeovers. Because the stroke is 30 mm, side-load risks are minimal, but always guide the load for straight travel. For position holding without live air pressure, select a SAIL or BSAI cylinder instead, as the rear adjuster here is a travel stop, not a lock. To match this ISO 15552 cylinder, verify the 100 mm bore, 30 mm stroke, 30 mm adjustment, PT G1/2 port, and -S magnet.
Quick checklist
- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100BX30-30S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N push at 0.9 MPa.
The rear adjuster screw acts as a travel stop, allowing you to shorten the effective stroke by up to 30 mm from the nominal 30 mm, yielding a 0-30 mm usable travel window. It does not lock the load without live air pressure.
