About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-40S
The AirTAC SAIJ160X475-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 14074N push force at 0.7 MPa. Its integrated SUS304 stainless steel rod provides superior corrosion resistance, while the PT tapered port ensures a tight pneumatic seal. By turning the rear screw, you achieve a usable travel window of 435-475 mm, allowing precise end-position tuning without swapping hardware.
This extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. Operating at 30-500 mm/s, it relies on variable air cushions at both ends to decelerate heavy loads. Remember that the rear adjuster functions strictly as a travel stop, not a lock; it cannot hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-40S Is Used
Heavy Press Tuning
Dial in the exact 435-475mm retract position during heavy press commissioning to accommodate different material thicknesses without external shims.
Product Changeover
Adjust the end-stop on the fly for varying package sizes on a high-thrust conveyor line, utilizing the 10053N pull force at 0.5 MPa.
Large Fixture Setup
Securely position large machining fixtures using the SUS304 rod, fine-tuning the stroke by up to 40mm to perfect the clamping depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-40S the Right Cylinder?
Select this 160mm bore when a 100mm cylinder (5497N push at 0.7 MPa) lacks the thrust for heavy positioning, or step down if 125mm (8590N) is sufficient. The 40mm adjustment window is ideal for product-size changeovers, letting you fine-tune the retract end on the fly instead of adding external stops. For a direct ISO 15552 replacement, match the 475mm stroke, 40mm adjust code, PT G3/4 port, and -S magnet.
Because the 475mm stroke is long and unsupported, the 40mm rod diameter must carry significant side loads, requiring an external guide to prevent rod bending. If your process demands true load-holding without continuous air pressure, the rear stopper here will not suffice; instead, specify an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX475-40S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 13236N of pull force. At 0.5 MPa, it delivers 10053N push and 9425N pull.
The rear adjuster acts as a mechanical stop that trims the effective travel. For this 475mm nominal stroke cylinder, you can reduce the stroke by up to 40mm, creating a usable travel window of 435-475mm to fine-tune the end position.
