About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-50
The AirTAC SAIJ160X475-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 425 to 475 mm, allowing you to dial back the 475 mm nominal stroke by up to 50 mm during commissioning. This bore delivers substantial force, generating 14074 N of push thrust at 0.7 MPa, making it suitable for heavy-duty manipulation.
Built with a SUS304 stainless steel rod, this unit resists corrosion while handling high side loads. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set the end position, so it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-50 Is Used
Heavy Press Setup
Fine-tune the 425-475 mm travel end-stop during machinery commissioning to precisely set the pressing depth without machining new spacers.
Product Changeover
Quickly adjust the retract position on a packaging line when switching to different pallet sizes, using the 50 mm trim window.
Large Material Handling
Move heavy workpieces using the 14074 N push force at 0.7 MPa, relying on the SUS304 rod for durability in harsh environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-50 the Right Cylinder?
Select this 160 mm bore when an application requires heavy force between the 100 mm bore (5497 N push at 0.7 MPa) and the massive 200 mm bore (21991 N push). The adjustable 50 mm travel window is ideal for product changeovers, letting you fine-tune the retract end-position without swapping the cylinder or adding external stops. Because the 475 mm stroke is relatively long, an external guide is recommended to prevent excessive rod side-loading.
To replace an ISO 15552 cylinder, match the 160 mm bore, 475 mm stroke, and 50 mm adjustment range. This model uses a PT G3/4 port and supports mountings Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your process requires the load to be held mechanically without continuous air, use a SAIL or BSAI cylinder instead, as this adjuster is not a lock.
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 SAIJ160 Adjustable Cylinder SAIJ160BX475-50 FAQ
A rear screw stopper lets you mechanically shorten the 475 mm nominal stroke by up to 50 mm, giving an effective travel range of 425-475 mm. It sets the end position but does not lock the load without air pressure.
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can deliver up to 2050 kgf at the maximum 1.0 MPa pressure.
