About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X110-40S
The AirTAC SAIJ160X110-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 110 mm travel by up to 40 mm. This creates a precise 70-110 mm usable travel window, enabling fine end-position tuning at commissioning without swapping the barrel or adding external stops. It delivers a substantial 14074 N push force at 0.7 MPa.
The 40 mm carbon steel rod and M36x2 thread provide a robust interface capable of handling high side loads, though long unsupported strokes still require an external guide. The extruded aluminum barrel features sensor grooves on both sides, and the included magnet (-S) integrates directly with AirTAC CMSE reed and DMSE electronic solid-state switches. Sealing options include standard TPU, high-temperature Viton H, or NBR N to suit various environments.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X110-40S Is Used
Machine Changeover
Dial in the 70-110 mm travel window during product size changes on a packaging line without replacing the cylinder or bolting on external stops.
Heavy Pressing Operations
Leverage the 14074 N push force at 0.7 MPa for heavy pressing or clamping tasks, fine-tuning the exact end-position to avoid over-travel.
Variable End-Stop Setup
Use the 40 mm rear adjustment screw to set precise retract end-positions during machine commissioning, accommodating mechanical tolerance stack-ups.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X110-40S the Right Cylinder?
Choose this 160 mm bore when an application requires heavy thrust between the 63 mm bore (2182 N push at 0.7 MPa) and the 200 mm bore (21991 N push). The adjustable stroke is ideal for variable end-stops or machine changeovers, whereas a fixed SAI cylinder is preferred when the exact travel is known and locked. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
When matching an ISO 15552 replacement, verify the 110 mm stroke, 40 mm adjuster, PT tapered port thread, and the -S magnet. Because the stroke is 110 mm, a side-load guide is not explicitly mandated but is recommended for heavy lateral loads. Remember that the rear adjuster acts as a travel stop and does not hold the load without live air; for position holding without pressure, consider an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock.
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 SAIJ160X110-40S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm from the nominal 110 mm, providing a 70-110 mm adjustable travel window. It acts as a mechanical stop to fine-tune the retract end position without needing a different cylinder.
At a 0.7 MPa operating pressure, the SAIJ160X110-40-S generates a push force of 14074 N and a pull force of 9425 N. It can deliver up to 18095 N push force at 0.9 MPa.
