About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-100
The AirTAC SAIJ160X185-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 85-185 mm, allowing you to dial back the 185 mm nominal stroke by up to 100 mm during machine commissioning. In the 160 mm bore class, it delivers substantial thrust, generating 18095 N of push force and 9425 N of pull force at a 0.9 MPa operating pressure.
This adjustable variant uses a carbon steel piston rod with an M36x2 thread, designed to handle heavy loads. The extruded aluminum barrel includes sensor grooves on both sides, and the standard PT G3/4 porting matches the bore size. The rear stopper mechanism lets you fine-tune end positions without swapping out the entire cylinder or adding external stops.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-100 Is Used
Heavy Press Tuning
Fine-tune the 85-185 mm stroke window on heavy presses to accommodate different material thicknesses without changing the cylinder.
Machine Changeover
Use the 100 mm rear adjuster to rapidly set new end-stops during production line changeovers, eliminating the need for external stopper hardware.
Large Assembly Jigs
Leverage the 18095 N push force at 0.9 MPa for large-scale assembly jigs where exact positioning and heavy clamping are required.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-100 the Right Cylinder?
Choose this 160 mm bore model when your application requires extreme force—stepping down to a 125 mm bore drops the 0.5 MPa push force to 6136 N, whereas this SAIJ160X185-100 provides 10053 N at the same pressure. The 100 mm adjustment range is ideal for product changeovers on heavy machinery, letting operators set variable end-stops on the fly instead of machining custom spacers. The cylinder supports speeds of 30-500 mm/s.
As an ISO 15552 interchangeable profile cylinder, it uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. The rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. Because the stroke is 185 mm, external guiding is recommended to prevent rod side-loading.
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 SAIJ160X185-100 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 100 mm, providing a usable travel window of 85-185 mm. The adjuster acts as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
At 0.9 MPa, the SAIJ160X185-100 generates 18095 N of push force and 9425 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 2050 kgf.
