Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-30S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 900mm 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 SAIJ100X900-30S
The AirTAC SAIJ100X900-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 870-900 mm. It delivers a robust 3927 N push force at 0.5 MPa, scaling up to 7068 N at 0.9 MPa, making it highly suitable for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for precise detection using CMSE reed or DMSE electronic switches.
Equipped with a 25 mm carbon steel rod and an M20x1.5 thread, it handles substantial side loads, though the 900 mm stroke length necessitates an external guide to prevent rod sag. The rear adjuster acts solely as a mechanical stop to fine-tune the retract position without needing external blocks, but it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-30S Is Used
Heavy Press Tuning
Dial in the exact 870-900 mm retract position during machine setup to accommodate varying workpiece heights without changing out the entire cylinder assembly.
Product Diversion
Adjust the stroke end-stop on the fly during line changeovers to handle different package sizes, ensuring the 7068 N push force meets the new payload requirements.
Automated Assembly
Fine-tune the end position of heavy tooling fixtures, using the rear stopper to compensate for mechanical wear over time while relying on DMSE sensors for confirmation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-30S the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (providing 2513 N push at 0.5 MPa) is insufficient for your tooling payload. The 30 mm adjustment range is ideal for fine-tuning the end-stop during machine commissioning or product changeover, avoiding the need to physically swap a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
When specifying a replacement, verify the 900 mm stroke, 30 mm adjustment range, G1/2 port with PT threads, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the stroke is 900 mm, always pair it with an external linear guide to manage deflection and protect the rod seals.

- ✓ 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 SAIJ100X900-30S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to trim the effective travel back by up to 30 mm, creating a usable stroke window of 870-900 mm. It functions as a mechanical stop for end-position tuning and is not a locking device.
