About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-30
The AirTAC SAIJ160X185-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial back the 185mm nominal stroke by up to 30mm. This yields a usable travel window of 155-185mm, enabling exact end-position tuning at commissioning without swapping hardware or adding external stops. It delivers substantial force, pushing 14074N and pulling 9425N at 0.7 MPa.
This heavy-duty unit uses a 40mm carbon steel rod with an M36x2 thread to handle high side loads, and runs at 30-500 mm/s. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember the rear screw is a travel stop, not a lock; use SAIL or BSAI for load-holding without live air.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-30 Is Used
Machine Changeover
Fine-tune the 155-185mm stroke end-position rapidly during product size transitions on a packaging line without changing cylinders.
Heavy Pressing
Leverage the 14074N push force at 0.7 MPa for heavy-duty pressing and forming tasks requiring precise depth control.
Variable End-Stops
Use the rear screw to set exact retraction limits during commissioning, avoiding the need to bolt on external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-30 the Right Cylinder?
Select this 160mm bore when a 125mm bore (8590N push at 0.5 MPa) is insufficient, but a 200mm bore is excessive. The adjustable 155-185mm travel is ideal for machine setups requiring variable end-stops during product changeovers, unlike a fixed-stroke SAI. Because the 185mm stroke is under 300mm, side-load guidance is less critical than on longer strokes, though the 40mm rod still provides excellent rigidity.
For ISO 15552 interchangeability, match the 160mm bore, 185mm stroke, 30mm adjustment, PT G3/4 port, and your required mounting. This configuration lacks a magnet (-S), so position sensing requires a different setup or a custom rod. Note that the rear adjuster and air cushions only set the travel end, not a secure hold.
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 SAIJ160X185-30 FAQ
The rear adjuster acts as a mechanical stop that trims the effective travel back by up to 30mm, providing a 155-185mm usable stroke window. It sets the end position but does not lock the load without live air pressure.
At 0.7 MPa, it provides a push force of 14074N and a pull force of 9425N. At 0.5 MPa, the push force is 10053N.
