About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-10S
The AirTAC SAIJ100X165-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, generating 5497N of push force at 0.7 MPa and up to 7068N at 0.9 MPa. The integrated -10 adjustment mechanism allows you to fine-tune the effective travel within a 155-165 mm window, making it highly effective for product-size changeovers without swapping out the entire actuator.
This variant features a SUS304 stainless steel rod for excellent corrosion resistance and includes a magnet (-S) for position sensing. It is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The extruded aluminum barrel design maintains a true ISO 15552 mounting interface, dimensionally interchangeable with comparable profile cylinders.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-10S Is Used
Machine Changeovers
Dial in the 10mm stroke adjustment window during product-size changeovers to set exact retract positions without machining new hard stops.
Heavy Clamping Fixtures
Leverage the 7068N push force at 0.9 MPa to secure heavy workpieces, using the rear screw to fine-tune the clamping depth precisely.
Corrosive Environment Actuation
Rely on the SUS304 stainless steel rod and adjustable end-stop for positioning tasks in washdown or mildly corrosive manufacturing settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX165-10S the Right Cylinder?
Select this 100mm bore actuator when an application requires heavy thrust combined with precise end-position tuning at commissioning. If your setup needs less force, stepping down to an 80mm bore yields 3518N push at 0.5 MPa, whereas moving up to a 125mm bore provides 6136N. Choose this adjustable-stroke SAIJ model over a fixed SAI when you need a variable end-stop to dial in the exact retract position on the fly.
Because the nominal stroke is 165mm, external guidance is recommended to manage side loads. Remember that the rear adjuster functions purely as a travel stop and does not hold the load without live air pressure; for secure load-holding without continuous air, consider an AirTAC SAIL or BSAI cylinder. This configuration uses PT tapered ports and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100BX165-10S FAQ
At 0.5 MPa it provides 3927N push and 3681N pull. At 0.7 MPa it delivers 5497N push, and at 0.9 MPa it reaches 7068N push force.
A rear adjusting screw acts as a stopper, allowing you to shorten the 165mm nominal stroke by up to 10mm, creating a usable travel window of 155-165mm. It functions as a travel stop and does not lock the load without live air pressure.
