About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X20-10
The AirTAC SAIJ160X20-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 10 to 20 mm, allowing you to dial back the nominal 20 mm stroke by up to 10 mm during commissioning without adding external stops. In this bore size, it generates a substantial 10053 N of pull force at 0.5 MPa and up to 18095 N of push force at 0.9 MPa.
This extruded aluminum barrel design includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. The robust 40 mm carbon steel rod and M36x2 thread handle high side loads well, while the PT tapered port threading ensures a tight pneumatic connection. The rear adjuster functions purely as a travel stop to set deceleration, not as a lock to hold the load without live air.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X20-10 Is Used
Short-Stroke Clamping
Applies up to 18095 N of push force at 0.9 MPa for securing heavy workpieces, with a 10-20 mm travel window to dial in the exact clamp position.
End-Stop Calibration
The rear adjusting screw allows operators to fine-tune the retract position on the fly during product changeovers without swapping out the cylinder.
Heavy Assembly Presses
Provides reliable, short-travel pressing action for heavy-duty assembly lines, utilizing the 40 mm carbon steel rod to manage demanding mechanical loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X20-10 the Right Cylinder?
Select this 160 mm bore adjustable-stroke cylinder when an application requires immense force combined with very short, finely-tuned travel. If you need less thrust, stepping down to the 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas moving up to the 200 mm bore provides 15080 N of pull. Choose the SAIJ adjustable version over a fixed SAI cylinder when you need variable end-stops for product changeovers or precise machine setup. To replace an ISO 15552 cylinder, match the 160 mm bore, 20 mm stroke, 10 mm adjustment, PT G3/4 port, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set. Since this model lacks a magnet (-S), it will not work with CMSE or DMSE sensors without a specification change.
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 SAIJ160X20-10 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 adjuster acts as a mechanical stop that lets you shorten the effective travel from 20 mm down to a minimum of 10 mm, creating a 10-20 mm usable window. It only sets the travel end point and does not lock or hold the load without continuous air pressure.
