About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-20S
The AirTAC SAIJ200X175-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the end position at commissioning without swapping the cylinder or adding external stops. It features a 200 mm bore, a PT tapered G3/4 port, and a SUS420J2 stainless steel rod (code A). With a nominal 175 mm stroke and a 20 mm adjustment range, it provides a usable travel window of 155-175 mm to perfectly dial in your machine changeovers.
Delivering 15708 N of push force and 15080 N of pull force at 0.5 MPa, this massive actuator is built for heavy-duty work. It includes a magnet for position sensing, compatible with AirTAC CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical travel stop to set deceleration and end-points; it is not a lock and cannot hold the load without live air pressure. For load-holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-20S Is Used
Heavy Machinery Changeover
Dial in the 155-175 mm travel window during heavy equipment product changeovers without replacing the actuator or bolting on external stops.
Press End-Stop Tuning
Use the rear adjuster to precisely set the deceleration point and final end-position for large pressing operations requiring up to 15708 N of force.
Large Load Positioning
Position heavy pallets or transfer carriages, relying on the 40 mm SUS420J2 stainless steel rod to withstand demanding industrial side-loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-20S the Right Cylinder?
Choose this 200 mm bore model when you need extreme thrust up to 15708 N at 0.5 MPa, stepping up from a 160 mm bore that provides 10053 N. An adjustable stroke is ideal for product-size changes on a line, letting you trim the travel window from 155 to 175 mm on the fly. To replace an ISO 15552 cylinder, match the 200 mm bore, 175 mm stroke, 20 mm adjustment, PT G3/4 port, and the -S magnet requirement. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets.
Because this cylinder uses a robust 40 mm diameter rod with an M36x2 thread, it handles high side-loads well, but for any application approaching the maximum stroke limits, an external guide is still recommended to prevent premature seal wear. The standard speed range for this large bore is 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 SAIJ200 Adjustable Cylinder SAIJ200AX175-20S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. The standard operating speed range for this large-bore actuator is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 175 mm down to 155 mm, giving a 155-175 mm usable travel window. It only sets the travel end and deceleration; it does not lock or hold the load without live air pressure.
