About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-30
The AirTAC SAIJ100X90-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 60-90 mm usable travel window from its 90 mm nominal stroke. Delivering 3927 N of push force at 0.5 MPa, it uses a 25 mm carbon steel rod and an M20x1.5 thread to handle high side loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This model allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-30 Is Used
Machine Changeover
Dial in the 60-90 mm travel window during product size transitions on packaging lines without bolting on external physical stops.
Variable End Stops
Fine-tune the retract position at machine commissioning to perfectly seat components using the 30 mm rear adjustment range.
Assembly Actuation
Leverage the 3927 N push force at 0.5 MPa for heavy pressing operations while trimming the stroke to match fixture limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-30 the Right Cylinder?
Choose this 100 mm bore when 80 mm is insufficient, as it jumps from 2513 N to 3927 N of push force at 0.5 MPa. An adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers, unlike a fixed-stroke SAI cylinder. The standard PT tapered ports and M20x1.5 rod thread ensure robust connections.
Because the rear adjuster and air cushions only manage travel ends, this cylinder will not hold a load without live air. For dead-air load holding, select a SAIL or BSAI cylinder. Operating speed ranges from 30 to 800 mm/s. No magnet is specified, so position sensing requires confirming sensor compatibility.
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 SAIJ100X90-30 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 reaches 7068 N.
The SAIJ100X90-30 has a 90 mm nominal stroke with a rear adjuster that allows you to trim the effective travel back by up to 30 mm. This creates a 60-90 mm adjustable window for fine-tuning the end position at commissioning.
