About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-10S
The AirTAC SAIJ160X375-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 365 to 375 mm, allowing you to dial back the stroke by up to 10 mm during commissioning without swapping the unit or adding external stops. Built for heavy tasks, the 160 mm bore generates 14074 N of push force at 0.7 MPa.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop to set the retract end position; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-10S Is Used
Heavy Assembly Pressing
Dial in the exact 365-375 mm end-stop during machine setup to apply precise 14074 N clamping force on large fabricated components.
Product Size Changeover
Quickly adjust the retract position by up to 10 mm to accommodate slightly different product lengths on a high-tonnage conveyor line.
Corrosive-Resistant Forming
Leverage the SUS304 rod and 18095 N pull force at 0.9 MPa for metal bending operations where moisture or corrosive coolants are present.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-10S the Right Cylinder?
Selecting this 160 mm bore over a smaller 125 mm bore steps your 0.5 MPa pull force up from 5734 N to 9425 N, providing the necessary thrust for high-load forming or clamping. The adjustable 10 mm window is ideal for fine-tuning end stops during product changeovers on an assembly line. For position holding without continuous air pressure, this cylinder is not a lock; you would need an external pilot-operated check valve or an AirTAC SAIL pneumatically released lock cylinder.
To match this ISO 15552 footprint for a direct replacement, verify a 160 mm bore, 375 mm stroke, up to 10 mm adjustment, PT tapered ports, and the -S magnet. Because the 375 mm stroke is relatively long, the 40 mm diameter rod and M36x2 thread handle substantial loads, but an external guide is recommended to prevent side-load damage on unsupported extensions.
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 SAIJ160BX375-10S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides 18095 N of push force and 16965 N of pull force. The maximum thrust at 1.0 MPa is 2050 kgf.
A rear mechanical screw stopper lets you shorten the effective travel from the nominal 375 mm down to 365 mm. This allows fine-tuning the retract end position at commissioning without adding external stops.
