About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-10S
The AirTAC SAIJ200X170-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end-position without swapping the unit. By turning the external stopper screw, you can dial back the nominal 170 mm travel by up to 10 mm, creating a precise 160-170 mm usable window for exact machine setup. This 200 mm bore generates a massive 15708 N of thrust at 0.5 MPa, making it suited for heavy-duty pressing and clamping.
This SKU features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works directly with AirTAC CMSE reed and DMSE electronic solid-state switches. It utilizes variable air cushions at both ends to decelerate the high kinetic energy of this large bore, operating at speeds of 30-500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-10S Is Used
Heavy Press Tuning
Dial in the exact 160-170 mm end-stop for heavy pressing tasks, allowing precise depth control without machining custom external stoppers.
Machine Changeover
Quickly adjust the retract position by up to 10 mm during product size changes on the line, minimizing downtime and tooling swaps.
Large Clamp Positioning
Fine-tune the clamping reach on large fabricated parts, using the 15708 N thrust to secure heavy workpieces while setting the exact travel limit.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-10S the Right Cylinder?
Selecting this 200 mm bore model is appropriate when your application requires extreme force, such as 15708 N of push force at 0.5 MPa, and you need the flexibility to trim the travel window down to 160 mm during commissioning. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which saves space and air consumption. The rear adjuster acts purely as a mechanical travel stop to set the end position; it does not lock or hold the load without live air pressure. For true fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 170 mm nominal stroke, 10 mm adjustment range, PT G3/4 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts. Because the 170 mm stroke is relatively short for this massive bore, side-load risks are minimal, but the 40 mm rod diameter and M36x2 thread provide excellent rigidity for off-center loads.
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 SAIJ200AX170-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can deliver a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 170 mm nominal stroke by up to 10 mm, providing a usable travel window of 160 to 170 mm. It sets the travel end-position but does not lock or hold the load without continuous air pressure.
