About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-10S
The AirTAC SAIJ100X65-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 65 mm nominal stroke that can be fine-tuned down by up to 10 mm, creating a precise 55-65 mm usable travel window for exact end-position calibration. Delivering a robust 3927 N of push force at 0.5 MPa, it handles heavy loads with ease.
This variant includes a standard carbon steel rod and a built-in magnet (-S) for position sensing. It works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches fitted into the dual-side sensor grooves on the extruded aluminum barrel. The rear screw acts purely as a travel stop for commissioning flexibility, so it will not hold the load dynamically without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-10S Is Used
Machine Setup Changeover
Dial in the 55-65 mm travel window during product line changeovers to accommodate slightly different part sizes without replacing the actuator.
Variable End-Stop Tuning
Use the rear adjusting screw to fine-tune the retraction end position during commissioning, ensuring perfect alignment of heavy clamping fixtures.
Heavy Assembly Positioning
Leverage the 3927 N push force at 0.5 MPa to move and position heavy components accurately along the production line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-10S the Right Cylinder?
Choose this 100 mm bore when you need substantial thrust that smaller neighbors cannot provide; stepping down to an 80 mm bore drops your 0.5 MPa push force to 2513 N. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers without physically swapping the cylinder or adding external stops. If your application requires true load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on this adjuster.
When matching your ISO 15552 replacement parameters, verify the 65 mm stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet option. Mounting choices are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300 mm, side-load stress on the 25 mm rod is minimal, though external guides are still recommended for heavy lateral loads.
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 SAIJ100X65-10S 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 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the 65 mm nominal stroke by up to 10 mm, providing a usable travel window of 55 to 65 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
