About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-40S
The AirTAC SAIJ160X175-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty automation. It features a carbon steel rod and a built-in magnet (-S) for use with CMSE reed and DMSE electronic sensors. With a 160mm bore, it generates 14074N of push force at 0.7 MPa, utilizing a G3/4 PT port to handle significant air volumes efficiently.
This model provides a usable travel window of 135-175mm, allowing you to trim the effective stroke by up to 40mm during commissioning without swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-40S Is Used
Heavy Press Tuning
Fine-tune the 135-175mm travel window during setup to precisely control heavy pressing operations without machining new hard stops.
Product Changeovers
Quickly adjust the rear stopper by up to 40mm to accommodate different product sizes on an automated assembly line.
Robotic End Effectors
Leverage the 14074N push force at 0.7 MPa and CMSE/DMSE sensor feedback for reliable heavy-part manipulation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-40S the Right Cylinder?
Choose this 160mm bore cylinder when an application demands high thrust, such as 14074N push at 0.7 MPa, but requires precise end-position tuning. If you need less force, stepping down to a 125mm bore yields 8590N push at 0.7 MPa. The adjustable stroke is ideal for product changeovers, letting you dial in the 135-175mm travel window via the rear screw rather than adding external stops. Remember that the adjuster is a travel stop, not a lock; for load-holding without live air, consider an AirTAC SAIL or BSAI cylinder.
Because this cylinder features a 175mm stroke, it is below the 300mm threshold that typically requires external guidance, but the substantial 40mm rod diameter and M36x2 thread provide excellent rigidity and side-load resistance. To match this SKU exactly for an ISO 15552 replacement, specify the 160mm bore, 175mm stroke, 40mm adjustment, G3/4 PT port, and the -S magnet option.

- ✓ 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 SAIJ160X175-40S FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke by up to 40mm. This creates a usable travel window of 135-175mm, enabling fine-tuning at commissioning without replacing the cylinder.
At an operating pressure of 0.7 MPa, the SAIJ160X175-40-S generates a push force of 14074N and a pull force of 9425N. It can deliver a maximum push force of 18095N at 0.9 MPa.
