About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-40
The AirTAC SAIJ160X175-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 10053N push force at 0.5 MPa and operates with a 135-175mm usable travel window, letting you trim up to 40mm off the 175mm nominal stroke. The standard carbon steel rod and PT tapered port threads ensure durable, high-flow pneumatic performance for heavy-duty cycles.
This extruded aluminum barrel design includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop for end-position tuning during commissioning or product changeover, meaning it cannot hold a load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-40 Is Used
Heavy Press Fine-Tuning
Dial in the exact 135-175mm retraction distance during machine setup to accommodate varying material thicknesses without mechanical modifications.
Product Changeover Stops
Quickly adjust the end-of-stroke position on a heavy assembly line when switching between different product sizes, using the 40mm trim window.
Large Fixture Actuation
Provide high-force clamping or positioning where the final 40mm of travel must be precisely set to avoid overstressing large workholding fixtures.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-40 the Right Cylinder?
Select this 160mm bore cylinder when your application requires substantial thrust—stepping down to a 125mm bore drops the 0.5 MPa push force to 6136N, while stepping up to 200mm yields 15708N. The SAIJ160X175-40 is chosen over a fixed-stroke SAI when you need a variable end-stop to fine-tune the retract position on the fly without swapping cylinders or adding external stops. When matching ISO 15552 replacements, verify the 175mm stroke, 40mm adjustment, PT port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ160X175-40 FAQ
At an operating pressure of 0.5 MPa, this 160mm bore cylinder provides a push force of 10053N and a pull force of 9425N. At 0.7 MPa, the push force increases to 14074N.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 40mm, creating a usable travel window of 135-175mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
