About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-30
The AirTAC SAIJ160X165-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window between 135 and 165 mm. Belonging to a high-force class, it delivers 9425 N of pull force at 0.5 MPa and reaches a maximum of 2050 kgf at 1.0 MPa. This makes it highly effective for moving substantial masses while allowing exact end-position tuning during commissioning without adding external stops.
It features a robust 40 mm carbon steel rod with an M36x2 thread, which provides excellent rigidity under heavy loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though a magnetic piston (-S) is required to activate them. The rear adjuster acts purely as a travel stop to decelerate the piston, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-30 Is Used
Heavy Press Tuning
Dial in the exact 135 to 165 mm stroke during heavy pressing operations to accommodate material thickness variations without repositioning the entire fixture.
Pallet Changeover
Adjust the rear stopper on the fly to handle different pallet sizes on a heavy-duty conveyor line, ensuring precise end-positioning without cylinder removal.
Large Assembly Setup
Fine-tune the end-of-stroke position for large automated assembly jigs, using the 40 mm rod and M36x2 thread to maintain rigidity under high side loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-30 the Right Cylinder?
Select this 160 mm bore when your application requires shifting heavy payloads that exceed the 1402 N pull force of a 63 mm cylinder, but you need less travel than a standard 200 mm bore unit offers. The 30 mm adjustment range is ideal for product changeovers on packaging lines, allowing operators to dial in the exact 135 to 165 mm end-position without swapping the cylinder. For load-holding without continuous air pressure, this cylinder is insufficient since the adjuster is a stop and not a lock; consider an AirTAC SAIL or BSAI series instead. When replacing an ISO 15552 cylinder, match the 160 mm bore, 165 mm stroke, 30 mm adjustment, PT G3/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface.

- ✓ 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 SAIJ160X165-30 FAQ
At a standard 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 2050 kgf.
The rear adjuster screw allows you to shorten the nominal 165 mm stroke by up to 30 mm, creating a usable travel window of 135 to 165 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
