About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX95-10S
The AirTAC SAIJ40X95-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 95 mm nominal stroke that can be fine-tuned down by 10 mm, yielding a usable travel window of 85-95 mm to perfectly dial in retract end positions. Delivering 879 N of push force at 0.7 MPa, it fits mid-range automation tasks. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed or DMSE electronic switches.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and is fitted with PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides. Mounting options are restricted to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX95-10S Is Used
Machine Changeover
Quickly adjust the 85-95 mm travel window during product size changes without swapping the cylinder or repositioning hard stops.
End-Position Tuning
Fine-tune the retract stroke at commissioning to achieve exact clamping or seating depths, compensating for mechanical tolerances.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for reliable actuation in packaging or food-grade environments requiring washdowns.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX95-10S the Right Cylinder?
Select this 40 mm bore when you need precise retract positioning without adding external stops; the rear screw allows on-the-fly commissioning adjustments that a fixed SAI cylinder cannot. If your application requires less force, stepping down to a 32 mm bore yields 563 N at 0.7 MPa, while stepping up to a 50 mm bore provides 1374 N. The 16 mm rod and M12x1.25 thread handle moderate side loads, though any stroke over 300 mm necessitates an external guide. To match this ISO 15552 footprint, specify: 40 mm bore, 95 mm stroke, 10 mm adjust, PT port, SUS304 rod, and a -S magnet.
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 SAIJ40 Adjustable Cylinder SAIJ40BX95-10S FAQ
At 0.7 MPa operating pressure, this 40 mm bore cylinder provides 879 N of push force and 528 N of pull force. It operates efficiently in the 30-800 mm/s speed range.
The rear adjuster acts as a mechanical stop that shortens the 95 mm nominal stroke by up to 10 mm, creating an 85-95 mm travel window. It only sets the end position and does not lock the load without live air.
