About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX165-40
The AirTAC SAIJ200X165-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive push and pull forces of 15708N and 15080N at 0.5 MPa. By integrating a 40mm adjustment mechanism at the retract end, this unit allows you to fine-tune the effective travel down from the 165mm nominal stroke to a minimum of 125mm. This built-in adjustability enables precise end-position calibration during commissioning without the need to swap out the entire cylinder or bolt on external stops.
Built for demanding environments, this configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance, paired with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for straightforward mounting of CMSE or DMSE switches. Remember that the rear adjuster functions strictly as a travel stop and deceleration point; it does not hold the load without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX165-40 Is Used
Heavy-Duty Press Tuning
Dial in the exact 125-165mm pressing depth during machine setup to accommodate different material thicknesses without replacing the cylinder.
Variable End-Stop Positioning
Use the rear adjuster screw to modify the retract end-position on the fly, ensuring precise mechanical stops for changing product dimensions.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and massive 15708N force to drive heavy assembly operations in wash-down or corrosive environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX165-40 the Right Cylinder?
Choose this 200mm bore when your application requires the highest standard force class in the SAIJ range, as stepping down to a 160mm bore reduces your 0.5 MPa push force to 10053N. The 40mm adjustable window is particularly valuable for heavy machinery that processes varying product sizes, allowing operators to dial in the exact end-stop during changeovers rather than machining new hard stops. For any application requiring position holding without air pressure, this cylinder is insufficient as the adjuster is not a lock; you should instead explore the SAIL air-released lock or BSAI clamp-lock series. Additionally, while the 40mm rod and M36x2 thread provide excellent rigidity, an unsupported 165mm stroke still necessitates an external guide to prevent excessive side-loading on the seals.

- ✓ 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 SAIJ200 Adjustable Cylinder SAIJ200BX165-40 FAQ
The nominal stroke is 165mm, but the rear adjuster allows you to shorten the effective travel by up to 40mm. This provides a usable adjustable stroke window of 125-165mm for fine-tuning the end position.
At 0.5 MPa operating pressure, the SAIJ200X165-40 provides a push force of 15708N and a pull force of 15080N. It can deliver up to 3204 kgf at the maximum 1.0 MPa pressure.
