About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-50S
The AirTAC SAIJ160X65-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty applications. It features a 160mm bore generating 18095N of push force at 0.9 MPa, alongside a SUS304 stainless steel rod for superior corrosion resistance. The integrated -S magnet enables precise position detection using CMSE reed or DMSE electronic sensors housed within the dual-side extruded aluminum barrel grooves.
This specific configuration provides a nominal 65mm stroke that can be fine-tuned down by up to 50mm, creating a usable travel window of 15 to 65mm. This built-in adjustability allows operators to dial in exact retract end-positions during commissioning or product changeovers without adding external stops. It utilizes PT tapered port threading (G3/4) and includes adjustable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-50S Is Used
Heavy Press Tuning
Dial in the exact 15 to 65mm pressing depth during machine commissioning to accommodate varying material thicknesses without swapping out the entire actuator.
Product Changeover
Quickly adjust the retract end-stop on a packaging line to handle different container sizes, utilizing the 50mm travel window to adapt positions on the fly.
Robotic End Effectors
Leverage the SUS304 stainless steel rod and CMSE/DMSE sensor compatibility for reliable heavy-load positioning in washdown or corrosive manufacturing environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-50S the Right Cylinder?
Choose this 160mm bore cylinder when an application demands substantial force, yielding 14074N push at 0.7 MPa. If a smaller footprint is acceptable, stepping down to a 125mm bore provides 8590N push at 0.7 MPa, but the SAIJ160X65-50-S is necessary for high-thrust tasks requiring exact end-position tuning. The 50mm adjustment range is ideal for prototyping or lines running multiple product sizes, functioning as a hard travel stop rather than a load-holding lock. For applications requiring the cylinder to maintain position without live air pressure, an external pilot-operated check valve or the AirTAC SAIL locking cylinder is required.
When replacing an ISO 15552 cylinder, verify the 160mm bore, 65mm nominal stroke, 50mm adjustment requirement, PT G3/4 port, and the -S magnet option. The mounting hardware must match the SAIJ subset, which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting the FB, CA, CB, and CR styles. Because the stroke is relatively short at 65mm, side-load stress on the M36x2 rod thread is minimal, though external guidance is always recommended for optimal seal longevity.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX65-50S FAQ
At 0.5 MPa it provides 10053N of push force and 9425N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 2050 kgf.
The rear adjuster acts as a mechanical stop that shortens the 65mm nominal stroke by up to 50mm, providing a usable travel window of 15 to 65mm. It only sets the end position and does not lock the load without continuous air pressure.
