About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-10S
The AirTAC SAIJ200X450-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 450 mm stroke that can be fine-tuned down by up to 10 mm, creating a precise 440-450 mm usable travel window for commissioning flexibility. Belonging to the 200 mm bore class, it delivers a robust 15708 N of thrust at 0.5 MPa and features a SUS420J2 stainless steel rod (option A) for heightened corrosion resistance.
This adjustable variant utilizes a PT tapered G3/4 port and includes a magnet for position sensing via CMSE reed or DMSE solid-state switches. The rear adjuster functions strictly as a mechanical stop to dial in the end position without swapping cylinders, while the extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-10S Is Used
Heavy Machinery Setup
Fine-tune the 440-450 mm travel window during heavy equipment assembly to achieve precise end-positioning without fabricating custom external stops.
Product Changeover
Quickly adapt automated lines for new product sizes by dialing in the rear stopper, saving changeover time on high-force 200 mm bore actuators.
Large Press Deceleration
Utilize the variable air cushions at both ends alongside the rear adjuster to safely set the end-of-stroke deceleration for massive industrial loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-10S the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands heavy thrust up to 15708 N at 0.5 MPa, but requires on-the-fly end-position tuning during product changeovers. If you need less force, stepping down to a 160 mm bore yields 10053 N of push force; however, this SAIJ200X450-10-S is necessary for high-load tasks. Because the stroke is 450 mm, the 40 mm rod diameter requires external guidance to prevent excessive side-loading on the seals.
The rear adjusting screw allows you to trim the stroke within the 440-450 mm window without adding external stops. Remember that the adjuster and air cushions only decelerate the load; they do not hold it without live air. For true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ200AX450-10S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It can deliver up to 3204 kgf at 1.0 MPa.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 450 mm down to 440 mm. This creates a 440-450 mm usable window for fine-tuning without replacing the cylinder.
