About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX195-10S
The AirTAC SAIJ40X195-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 628N of push force and 528N of pull force at 0.5 MPa, utilizing a 16mm piston rod with an M12x1.25 thread. The integrated -10 adjustment screw allows you to trim the effective travel back by up to 10mm, creating a precise 185-195mm usable stroke window for exact end-position tuning.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel houses sensor grooves on both sides, and the standard PT tapered porting is G1/4. You can fine-tune the retract end-stop at commissioning without adding external physical stops or swapping the entire cylinder.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX195-10S Is Used
Machine Setup & Changeover
Dial in the exact 185-195mm end-stop during product size changes without physically swapping cylinders or reworking fixture positions.
Variable End Positioning
Fine-tune the retract stroke by up to 10mm at commissioning to perfect the seating pressure of delicate components.
Diversion Gate Control
Adjust the gate travel window precisely on-site to accommodate different package widths moving down the line.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX195-10S the Right Cylinder?
Select this 40mm bore when an application requires precise positioning that a fixed-stroke SAI cannot provide. If your setup needs less force, stepping down to a 32mm bore yields 402N at 0.5MPa; if more thrust is required, a 50mm bore provides 982N. The SAIJ40X195-10-S is ideal for product changeovers on a line, allowing operators to dial in the 185-195mm travel window on the fly.
Because the stroke is 195mm, the 16mm rod handles standard loads well, but always ensure external guiding for any heavy off-center loads. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold its load without live air. For true pneumatic locking without pressure, consider the SAIL or BSAI series. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It 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 SAIJ40 Adjustable Cylinder SAIJ40BX195-10S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 195mm nominal stroke by up to 10mm, providing a usable travel window of 185-195mm. It only sets the travel end and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, it provides 628N of push force and 528N of pull force. At 0.7 MPa, the push force increases to 879N.
