Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-10S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 185mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-10S
The AirTAC SAIJ160X185-10-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster. It delivers 10053 N of push force at 0.5 MPa and 18095 N at 0.9 MPa. The rear stopper screw allows you to trim the 185 mm nominal stroke back by up to 10 mm, creating a precise 175-185 mm usable travel window for exact end-position tuning during commissioning. This carbon-steel rod version includes a magnet for CMSE reed and DMSE solid-state sensors.
Because the adjuster acts purely as a travel stop and does not lock the load, live air pressure is required to hold position. For true load-holding without pneumatic pressure, consider the SAIL or BSAI series. This extruded aluminum barrel omits the FB, CA, CB, and CR mounts, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-10S Is Used
Press Tonnage Setup
Dial in the exact 175-185 mm end position during heavy pressing setup to accommodate material thickness variations without replacing the actuator.
Product Changeover
Quickly adjust the stroke end-stop by up to 10 mm on automated packaging lines when switching to a slightly different pallet or product size.
Heavy Material Handling
Leverage the 10053 N push force at 0.5 MPa to move heavy bulk materials, using the rear screw to fine-tune the retraction end point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-10S the Right Cylinder?
Choose this 160 mm bore when 125 mm (6136 N at 0.5 MPa) is too weak but 200 mm (15708 N) is oversized. The 10 mm adjustment range is ideal for fine-tuning a fixed end-stop during machine setup or product changeover without swapping the cylinder or adding external stops. When matching ISO 15552 replacements, confirm the 185 mm stroke, 10 mm adjuster, PT port threads, and the -S magnet requirement.
With a 185 mm stroke, side-load risks are moderate, but the robust 40 mm rod and M36x2 thread handle higher bending moments. If your application involves long unsupported loads, external guidance is still recommended. The operating speed is 30-500 mm/s.
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 SAIJ160X185-10S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the 185 mm nominal stroke by up to 10 mm, providing a usable travel window of 175-185 mm. It is a travel stop for fine-tuning, not a load-holding lock.
