About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-30S
The AirTAC SAIJ100X65-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. Its 65mm nominal stroke can be dialed back by up to 30mm, creating a precise 35-65mm usable travel window for fine-tuning retract end positions during commissioning. This adjustability eliminates the need to swap cylinders or bolt on external stops when aligning machinery.
This bore features a robust 25mm carbon steel rod with an M20x1.5 thread, paired with a G1/2 PT tapered port for optimal airflow. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic solid-state switches. It utilizes variable air cushions at both ends and offers a speed range of 30-800 mm/s.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-30S Is Used
Product Size Changeovers
Quickly dial in the 35-65mm stroke window when switching between product lengths on a packaging line, avoiding mechanical rebuilds.
Precision End-Position Tuning
Fine-tune the retract distance during machine commissioning to perfectly seat heavy 100mm bore components without adding external stops.
Adjustable Forming Stops
Set exact material engagement depths on the fly, using the rear adjuster to accommodate varying material thicknesses in pressing operations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-30S the Right Cylinder?
Select this 100mm bore when an 80mm cylinder (providing 2513N push at 0.5 MPa) lacks the thrust for your clamping or lifting task, but you want to avoid the larger 160mm footprint. Choose the SAIJ adjustable-stroke design over a fixed SAI cylinder when your machine setup requires variable end-stops or product-size changeovers. The rear adjuster acts strictly as a mechanical stop to set the travel end and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 SAIJ100X65-30S FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 5497N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the 65mm nominal stroke by up to 30mm, providing a usable travel window of 35-65mm. It sets the end position but does not lock the load without continuous air pressure.
