About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-50
The AirTAC SAIJ200X1000-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the 1000 mm nominal stroke by up to 50 mm for a precise 950-1000 mm usable travel window. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers massive thrust up to 28274 N at 0.9 MPa. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE or DMSE electronic switches.
Because the rear stopper acts solely as a travel end-limit and deceleration point, it will not hold a load without live air pressure. For applications requiring true load-holding safety, you must explore the SAIL or BSAI series, or integrate an external pilot-operated check valve. This heavy-duty model uses the reduced SAIJ mounting set, omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-50 Is Used
Long-Stroke Positioning
Dial in the 950-1000 mm travel window during machine setup to perfectly align long-travel conveyors or heavy pushers without adding external stops.
Product Changeover
Quickly adapt the end-stop position on a packaging line when product sizes change, using the 50 mm rear adjuster to trim the stroke on the fly.
Heavy-Duty Pressing
Leverage the 28274 N push force at 0.9 MPa for massive pressing or forming tasks, fine-tuning the final contact position to the millimeter.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-50 the Right Cylinder?
Choose this 200 mm bore when you need extreme push force (15708 N at 0.5 MPa) that smaller bores cannot provide, rather than stepping down to a 160 mm bore. The 50 mm adjustment range is ideal for fine-tuning the end position during machine commissioning or product changeover without swapping the cylinder. To match this ISO 15552 replacement exactly, verify the 1000 mm stroke, 50 mm adjustment, PT G3/4 ports, and the SUS304 (B) rod material. Since the stroke is 1000 mm, the long unsupported travel requires an external guide to prevent excessive side-load wear on the 40 mm rod and M36x2 thread.
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 SAIJ200BX1000-50 FAQ
This 200 mm bore cylinder delivers a push force of 15708 N at 0.5 MPa and reaches 28274 N at 0.9 MPa. The pull force is slightly lower due to the rod area, peaking at 15080 N at 0.5 MPa.
The rear adjuster screw lets you shorten the 1000 mm nominal stroke by up to 50 mm, creating a 950-1000 mm usable travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without air pressure.
