About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-10S
The AirTAC SAIJ160X300-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 290 to 300 mm. It delivers substantial thrust, generating 10053 N of pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
This model features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear stopper allows precise end-position tuning during commissioning without adding external stops. Remember that this adjuster acts only as a travel stop and does not hold the load without continuous air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-10S Is Used
Heavy Press Tuning
Fine-tune the 290-300 mm end-stop on heavy pressing equipment to dial in exact material deformation without swapping cylinders.
Product Changeover
Adjust the rear stopper by up to 10 mm during packaging line size changeovers to accommodate different carton depths rapidly.
Machine Setup
Use the rear adjuster during initial commissioning to set the precise retracted position of heavy industrial machinery components.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-10S the Right Cylinder?
Select this 160 mm bore when an 80 mm cylinder lacks force (the 80 mm bore yields 2268 N pull at 0.5 MPa) and you need precise mechanical trimming at the end of a 300 mm stroke. Because the stroke is 300 mm, the 40 mm diameter rod and M36x2 thread handle significant loads, but an external guide is recommended to prevent excessive side-loading on the piston. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
For a drop-in ISO 15552 replacement, match the 160 mm bore, 300 mm stroke, 10 mm adjustment, PT ports, and the -S magnet. If your application requires true load-holding without live air pressure, this cylinder's adjuster will not act as a brake; consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock instead.
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 SAIJ160BX300-10S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force at 0.7 MPa. It reaches a maximum thrust of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 10 mm, creating a 290 to 300 mm usable travel window. It sets the end position but does not lock or hold the load without live air pressure.
