Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-50
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 175mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-50
The AirTAC SAIJ160X175-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers substantial thrust, pushing with 14074N and pulling with 9425N at 0.7 MPa. By integrating a rear stopper mechanism, this unit allows you to shorten the effective travel from its 175 mm nominal length down to as little as 125 mm, providing a 50 mm tuning window. This means you can fine-tune the retract end position at commissioning without adding external stops.
Built with an extruded aluminum barrel and sensor grooves on both sides, it accommodates AirTAC CMSE reed and DMSE electronic sensors if a magnet is specified later. The robust 40 mm carbon steel rod and M36x2 thread handle high side loads, while standard PT tapered ports ensure secure pneumatic connections. It uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-50 Is Used
Machine Setup & Changeover
Fine-tune the retract end position during product size changes on a production line, using the 50 mm adjustment window to avoid remounting cylinders.
Variable End-Stop Positioning
Dial in exact retraction stops for heavy-duty tooling or press operations where a fixed 175 mm stroke would be too rigid for varying material thicknesses.
Heavy-Duty Assembly Lines
Leverage the 14074N push force at 0.7 MPa to move substantial masses while retaining the flexibility to adjust the stroke end-point on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-50 the Right Cylinder?
Choose this 160 mm bore when 100 mm (5497N push at 0.7 MPa) is insufficient but 200 mm (21991N) is excessive. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, letting you dial in the exact 125-175 mm travel window instead of swapping a fixed-stroke SAI cylinder. Speeds are 30-500 mm/s for this large bore.
Remember that the rear adjuster acts only as a travel stop, not a lock; it cannot hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. To match this ISO 15552 cylinder, specify a 160 mm bore, 175 mm stroke, 50 mm adjustment, PT ports, and your required mounting.

- ✓ 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 SAIJ160X175-50 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 9425N. At 0.9 MPa, the push force increases to 18095N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 175 mm nominal stroke by up to 50 mm. This creates a usable travel window of 125-175 mm, allowing precise end-position tuning during commissioning without swapping the cylinder.
