About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-30S
The AirTAC SAIJ200X400-30-S is a double-acting ISO 15552 profile cylinder engineered for high-force tasks. It features a robust 40mm piston rod and delivers 21991N of push force at 0.7 MPa. The defining feature is the rear adjusting screw, which provides a usable travel window of 370 to 400mm, allowing you to trim up to 30mm off the nominal stroke.
This unit includes a magnet for position sensing, pairing directly with AirTAC CMSE reed and DMSE electronic switches housed in the dual-side sensor grooves. It uses an SUS420J2 stainless steel rod for superior corrosion resistance and accepts PT tapered port threads. The rear stopper allows precise end-position tuning during commissioning without adding external stops, though it acts purely as a travel stop and does not hold the load without live air.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-30S Is Used
Heavy Press Tuning
Dial in the exact 370-400mm end position during machine setup to accommodate varying material thicknesses without installing external physical stops.
Product Line Changeover
Quickly adjust the retract distance on a high-force assembly line when switching to a new product size, using the rear screw rather than replacing the entire cylinder.
High-Force Positioning
Leverage the 21991N push force at 0.7 MPa for moving massive payloads, fine-tuning the travel window by up to 30mm during commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-30S the Right Cylinder?
Select this 200mm bore cylinder when an application demands extreme thrust that smaller bores cannot provide; stepping down to a 160mm bore drops your 0.7 MPa push force to 14074N. The 30mm adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops to accommodate product-size changes on a line without physically swapping the actuator. For any stroke of 400mm, the long unsupported rod travel requires an external guide to prevent excessive side-loading, despite the heavy 40mm rod diameter.
This SAIJ configuration uses PT tapered ports and a SUS420J2 stainless steel rod. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. If the machine requires true load-holding without continuous air pressure, a standard SAIJ will not suffice; you must pivot to an SAIL air-released lock or BSAI clamp-lock cylinder instead.

- ✓ 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 SAIJ200AX400-30S FAQ
At an operating pressure of 0.7 MPa, this 200mm bore cylinder generates 21991N 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 effective travel from 400mm down to 370mm. This allows precise end-position tuning at commissioning, but it is only a stop and does not lock or hold the load without live air pressure.
