About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX475-50
The AirTAC SAIJ200X475-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. It features a SUS304 stainless steel rod and PT tapered ports. The integrated 50mm adjustment screw allows you to dial back the 475mm nominal stroke, creating a precise 425-475mm usable travel window for fine-tuning end positions during commissioning.
This extruded aluminum barrel design includes sensor grooves on both sides for flexible switch placement. Operating at speeds of 30-500mm/s, it utilizes variable air cushions at both ends to decelerate heavy loads smoothly. The rear stopper sets the retracted end position, but remember it acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX475-50 Is Used
Heavy Press Tuning
Fine-tune the 425-475mm travel window on high-tonnage pressing equipment to accommodate different material thicknesses without mechanical rebuilds.
Large Assembly Changeover
Adjust the rear stopper during production line changeovers to handle varying large-component dimensions quickly and accurately.
Long-Stroke Positioning
Leverage the 475mm stroke and SUS304 rod for robust positioning of heavy fixtures, relying on external guides to manage side loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX475-50 the Right Cylinder?
Choose this 200mm bore cylinder when an application demands extreme force, stepping up from a 160mm bore that provides 10053N push force at 0.5 MPa. The adjustable stroke is ideal for product changeovers on large machinery, allowing you to shift the end-stop by up to 50mm without swapping the cylinder or adding external stops. For load-holding without live air pressure, you must integrate an external rod lock or look at the SAIL or BSAI series, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 200mm bore, 475mm stroke, 50mm adjustment, PT ports, and your required mounting style. Because the stroke is 475mm, the M36x2 rod and long travel distance require an external guide to prevent excessive side-loading and premature seal wear. Supported mounts include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200BX475-50 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 475mm nominal stroke by up to 50mm, providing a usable travel window of 425-475mm. It sets the end position but does not lock the load without continuous air pressure.
