About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-40
The AirTAC SAIJ160X135-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 95 to 135 mm, allowing you to dial back the nominal 135 mm stroke by up to 40 mm during commissioning. Delivering a robust 14074 N of push force at 0.7 MPa, it handles heavy-duty positioning with ease.
This model features a 40 mm carbon steel rod with an M36x2 thread, providing high structural rigidity. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-40 Is Used
Product Changeover
Quickly fine-tune the retract end-stop by up to 40 mm when switching product sizes on a packaging line, eliminating the need to physically swap cylinders.
Heavy Press Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy assemblies, using the adjustable travel window to dial in the exact 95-135 mm contact point.
Machine Setup
Set precise mechanical end limits during initial commissioning without adding external stopper blocks to the machine frame.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-40 the Right Cylinder?
Choose this 160 mm bore cylinder when you need precise end-position tuning without swapping components; for lighter applications, a 125 mm bore offers 8590 N at 0.7 MPa. The adjustable rear stopper is ideal for product changeovers, but for true load-holding without live air, consider the SAIL or BSAI locking cylinders. To match this ISO 15552 replacement exactly, verify the 135 mm stroke, 40 mm adjustment, PT G3/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. While the 135 mm stroke is under the 300 mm threshold, the heavy 40 mm rod still requires external guidance to prevent side-loading damage.
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 SAIJ160X135-40 FAQ
At a standard 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can deliver up to 18095 N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke from the nominal 135 mm down to a minimum of 95 mm, creating a 95-135 mm travel window. This stopper only sets the end position and does not lock or hold the load without continuous air pressure.
