About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-30S
The AirTAC SAIJ160X105-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 105 mm travel by up to 30 mm. This creates a highly specific 75-105 mm usable stroke window, allowing precise end-position tuning during commissioning without swapping out the physical cylinder. Built with a robust 40 mm carbon steel rod and M36x2 thread, it handles heavy loads with substantial side-load resilience.
Delivering 14074 N of push force at 0.7 MPa, this bore size is designed for heavy-duty positioning. The extruded aluminum barrel features sensor grooves on both sides, and because this is the -S variant, it includes a magnet for use with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster functions strictly as a travel stop to fine-tune deceleration, not as a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-30S Is Used
Heavy Press Tuning
Dial in the exact 75-105 mm travel distance for a heavy stamping or pressing operation without machining new hard stops.
Multi-Product Lines
Quickly reconfigure the cylinder's end position on a conveyor line when switching between different product sizes or packaging formats.
Machine Commissioning
Fine-tune the final resting position of heavy actuators during machine setup to perfectly align tooling without cylinder removal.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-30S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore (providing 5497 N push at 0.7 MPa) is insufficient for your tooling weight, but a 200 mm bore (15708 N at 0.5 MPa) would be excessive overkill. The adjustable stroke is ideal for production lines that require variable end-stops for different product sizes, avoiding the need to maintain a massive inventory of fixed-stroke SAI cylinders for every possible travel length.
Because the nominal stroke is 105 mm, you bypass the need for external side-load guides required on longer 300 mm+ strokes. If your application requires the load to be held mechanically in place without live air pressure, note that this cylinder's adjuster will not do that; you should look at the SAIL air-released lock or BSAI clamp-lock series instead. This model features PT tapered ports and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAIJ160X105-30S 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 safely operate up to a maximum pressure of 1.0 MPa.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 30 mm. For this specific SAIJ160X105-30-S model, this means you can tune the usable travel window anywhere between 75 mm and 105 mm.
