About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-100S
The AirTAC SAIJ160X185-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a highly flexible 85-185 mm usable travel window. Driven by a robust 40 mm carbon steel rod and a G3/4 PT port, it generates 14074 N of push force at 0.7 MPa. This makes it exceptionally suited for heavy-duty operations requiring exact end-position tuning without swapping out the entire actuator.
Because the adjuster acts purely as a mechanical stop, it does not lock the load without continuous live air pressure. For position holding, external pilot-operated check valves or a related BSAI clamp-lock cylinder are required. This -S variant includes a magnet for CMSE reed and DMSE electronic sensors, which seat neatly into the dual-side extruded aluminum barrel grooves.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-100S Is Used
Heavy Press Tuning
Dial in the exact 85 to 185 mm end-stop during heavy press commissioning to accommodate varying material thicknesses without replacing the actuator.
Product Changeover
Rapidly adjust the retract distance on automated assembly lines when switching between different large-scale product dimensions.
Large Fixture Setup
Fine-tune the clamping reach on heavy industrial fixtures, relying on the 40 mm carbon steel rod to withstand demanding operational stresses.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-100S the Right Cylinder?
Selecting this 160 mm bore actuator over a smaller 125 mm option provides a significant thrust upgrade, jumping from 8590 N to 14074 N at 0.7 MPa. The generous 100 mm adjustment range is ideal for product changeovers on large machinery, allowing operators to dial in the retract end-position on the fly rather than machining external stops. If your application requires a fixed travel distance with no variance, the standard SAI fixed-stroke cylinder is a simpler alternative.
When configuring an ISO 15552 replacement, match the 160 mm bore, 185 mm stroke, 100 mm adjuster, G3/4 PT ports, and the -S magnet requirement. The approved SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the 185 mm stroke is near the maximum standard limit for this bore, ensure adequate external guiding to handle side loads, and note that speeds are capped at 30-500 mm/s.
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 SAIJ160X185-100S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder produces 14074 N of push force and 9425 N of pull force. It can safely operate up to a maximum pressure of 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back by up to 100 mm from the 185 mm nominal stroke, creating an 85 to 185 mm usable window. It only sets the travel end and does not hold the load without live air.
