About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-30S
The AirTAC SAIJ200X950-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end-position. It provides a usable travel window of 920-950 mm, enabling precise variable end-stops during machine setup or product changeovers without swapping the hardware. Built with a SUS420J2 stainless steel rod and a -S magnet for CMSE reed and DMSE electronic sensors, it delivers massive thrust up to 21991 N at 0.7 MPa.
This 200 mm bore profile cylinder uses PT tapered ports and dual-side sensor grooves. The rear adjuster acts strictly as a mechanical stop to set deceleration, meaning it will not hold a load safely without live air pressure. For true load-holding requirements, an external rod lock or an AirTAC SAIL/BSAI model is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-30S Is Used
Heavy Press Tuning
Dial in the exact 920-950 mm retract position on a heavy press during setup, ensuring perfect alignment without machining custom spacers.
Large Mold Changeover
Quickly adapt the end-stop for different large mold sizes on an automated line, using the rear screw to shift the 30 mm travel window.
Heavy-Duty Positioning
Position massive components accurately using the 21991 N force at 0.7 MPa, relying on the adjuster to set the precise resting point.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-30S the Right Cylinder?
Choose this 200 mm bore unit when your application requires extreme force, offering 21991 N push at 0.7 MPa, stepping up from a 160 mm bore that provides 14074 N. The 30 mm adjustment window is ideal for variable end-stop tuning at commissioning, avoiding the need to bolt on external stops or buy a fixed-stroke SAI cylinder. To match this ISO 15552 replacement exactly, specify: 200 mm bore, 950 mm stroke, 30 mm adjustment, PT ports, and the -S magnet.
Because this cylinder features a long 950 mm stroke, the 40 mm diameter rod and M36x2 thread will still experience leverage forces. An external guide is strongly recommended to prevent excessive side-loading and premature seal wear over this extended travel distance.
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 SAIJ200AX950-30S FAQ
At a 0.7 MPa operating pressure, this 200 mm bore cylinder generates 21991 N of push force and 21991 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw lets you mechanically shorten the 950 mm nominal stroke by up to 30 mm, creating a 920-950 mm travel window. It functions as an end-stop for position tuning and is not a lock, so live air is still needed to hold the load.
