About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-50S
The AirTAC SAIJ160X185-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 135 mm from the 185 mm nominal stroke. Built with a 160 mm bore, it delivers substantial thrust, pushing 14074 N at 0.7 MPa and reaching 18095 N at 0.9 MPa. The carbon steel rod and M36x2 thread provide a robust interface for heavy loads.
This variant includes a magnetic piston (-S) for position sensing, working seamlessly with AirTAC CMSE reed switches and DMSE electronic sensors housed in the dual-side barrel grooves. It uses a PT tapered port and operates at speeds between 30-500 mm/s. The rear adjustment screw acts purely as a travel stop for end-position tuning, not as a lock, meaning live air pressure is always required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-50S Is Used
Heavy Press Tuning
Dial in the exact 135-185 mm end-stop during heavy press commissioning to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the retract end-position on a packaging line when switching to a new product size, leveraging the 50 mm trim range to avoid mechanical rebuilds.
Automated Assembly
Use the magnetic piston with DMSE sensors to confirm end-of-stroke positions while fine-tuning the travel window for precise heavy-part placement.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-50S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (4523 N at 0.9 MPa) lacks the power for heavy positioning tasks, or step down from a 200 mm bore if you want to reduce physical size while still achieving 18095 N of push force at 0.9 MPa. The 50 mm adjustable stroke window is ideal for machine setup and product changeover, allowing you to dial in the exact end-stop without swapping out the cylinder or adding external stops. For load-holding without continuous air pressure, select the SAIL or BSAI series instead, as this adjuster only sets the travel end. The dimensionally interchangeable ISO 15552 mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ160X185-50S FAQ
At 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. At 0.5 MPa, the push force is 10053 N.
The rear adjuster screw lets you shorten the 185 mm nominal stroke by up to 50 mm, creating a usable travel window of 135-185 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without live air pressure.
