Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-30S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 500mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-30S
The AirTAC SAIJ100X500-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 7068N of push force at 0.9 MPa and provides a usable travel window of 470 to 500 mm, letting you dial back the nominal 500 mm stroke by up to 30 mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and this specific configuration features a SUS304 stainless steel rod for superior corrosion resistance.
Equipped with a magnet for position sensing, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. The G1/2 port and M20x1.5 rod thread handle substantial pneumatic flow, while the adjustable end-stop acts purely as a travel limiter and does not hold the load without continuous air pressure. For load-holding requirements without live air, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-30S Is Used
Machine Setup Tuning
Dial in the exact 470 to 500 mm end position during initial equipment commissioning without machining new stopper blocks.
Product Changeover
Quickly adjust the travel window on automated lines when product sizes change, minimizing downtime between runs.
Heavy Forming Press
Provides 7068N of push force at 0.9 MPa for pressing or forming operations requiring precise bottom-dead-center control.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-30S the Right Cylinder?
Choose this 100 mm bore when you need heavy thrust beyond the 80 mm class (which provides 4523N push at 0.9 MPa) but want to avoid the larger 125 mm footprint. The adjustable stroke is ideal for product changeovers or fine-tuning end positions without swapping the cylinder or adding external stops. Because the nominal stroke is 500 mm, the M20x1.5 piston rod is highly susceptible to side loads; always use an external guide to prevent binding and premature seal wear.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 500 mm stroke, 30 mm adjustment range, PT tapered port thread, and the -S magnet requirement. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR brackets found in some standard series.
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 SAIJ100BX500-30S FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder generates 7068N of push force and 6681N of pull force. Maximum thrust is 801 kgf at 1.0 MPa.
A rear external screw allows you to trim the effective travel back by up to 30 mm from the 500 mm nominal stroke, creating a 470 to 500 mm usable window. This adjuster acts only as a mechanical stop and does not lock the load without live air pressure.
