About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-40
The AirTAC SAIJ160X165-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 125 to 165 mm window. Utilizing a 160 mm bore, it delivers a substantial 10053 N push force at 0.5 MPa and 14074 N at 0.7 MPa, making it well-suited for heavy-duty positioning tasks.
This model incorporates a carbon steel piston rod with an M36x2 thread, paired with a PT tapered port and a 50 mm cushion length to manage high kinetic energy during deceleration. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the direct mounting of AirTAC CMSE reed or DMSE electronic sensors if a magnet is specified later, while the rear stopper simplifies product changeovers without requiring external physical stops.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-40 Is Used
Heavy Machinery Positioning
Provides robust 10053 N thrust at 0.5 MPa for moving heavy structural components, using the 125-165 mm adjustable window to dial in exact alignment during machine assembly.
Product Size Changeovers
Allows operators to quickly reconfigure the end-stop by up to 40 mm on packaging lines handling varying pallet heights, eliminating the need to physically swap cylinders.
Precision Clamping Setup
Delivers reliable clamping force with a 50 mm air cushion to absorb shock, while the rear screw fine-tunes the retraction point to accommodate different workpiece tolerances.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-40 the Right Cylinder?
Selecting this 160 mm bore cylinder is appropriate when an application demands high thrust, such as 10053 N at 0.5 MPa, but requires less than the maximum output of a 200 mm bore (15708 N at 0.5 MPa). The adjustable 40 mm travel window is ideal for production lines that undergo frequent product size changeovers, enabling precise end-position tuning at commissioning without swapping out the entire actuator. For applications needing a fixed end-of-stroke without any rear trim capability, the standard AirTAC SAI series would be a simpler alternative.
When matching this cylinder for an ISO 15552 replacement, verify the 165 mm stroke, the 40 mm adjustment range, the PT G3/4 port, and the appropriate mounting attachment from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the stroke is 165 mm, the robust M36x2 rod thread handles side loads well, though any long unsupported overhang still necessitates an external guide. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking without pressure, consider the AirTAC SAIL or BSAI series.

- ✓ 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 SAIJ160X165-40 FAQ
The rear adjuster acts as an external mechanical stopper that allows you to shorten the nominal 165 mm stroke by up to 40 mm, providing an effective adjustable travel window of 125 to 165 mm. It sets the end position and works with the 50 mm air cushion for deceleration, but it does not lock the load without continuous air pressure.
At a 0.5 MPa operating pressure, the SAIJ160X165-40 generates 10053 N of push force and 9425 N of pull force. If the pressure is increased to 0.7 MPa, the push force rises to 14074 N.
