About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-20S
The AirTAC SAIJ200X100-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 100 mm nominal stroke to a precise 80-100 mm window. It delivers massive thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. This variant includes a magnet for position detection and uses a SUS304 stainless steel rod for superior corrosion resistance.
The integrated adjustment screw acts purely as a mechanical stop to set the retract end-position and works alongside the variable air cushions to decelerate the load. It does not lock or hold the load without live air pressure; for fail-safe load holding, you would need a related SAIL or BSAI series cylinder. This extruded aluminum profile barrel unit supports AirTAC CMSE reed and DMSE electronic sensors in its dual side grooves.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-20S Is Used
Product Changeover Tuning
Dial in the 80-100 mm travel window during machine setup to accommodate different product sizes without replacing the entire cylinder assembly.
Heavy Press Positioning
Leverage the 15708 N push force at 0.5 MPa to move heavy jigs into place, using the rear stopper to precisely set the final end-position.
Assembly Station Stops
Use the fine-tune adjustment to set exact retract distances on assembly lines, relying on the SUS304 rod for durability in varied environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-20S the Right Cylinder?
Choose this adjustable SAIJ model over a fixed-stroke SAI when your application requires variable end-stops or on-the-fly product changeovers without physically swapping the cylinder or adding external stopper blocks. When matching ISO 15552 interchangeable replacements, verify the 200 mm bore, 100 mm stroke, 20 mm adjustment range, PT tapered ports, and the -S magnet option. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N push force at 0.5 MPa, which might offer a more compact footprint.
Because the stroke is under 300 mm, the side-load risk from the 40 mm rod diameter is moderate, though long unsupported loads still require an external guide. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Operating speed is 30-500 mm/s.
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 SAIJ200BX100-20S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the 100 mm nominal stroke by up to 20 mm, creating an effective 80-100 mm travel window. It functions as a mechanical stop and does not lock the load without live air pressure.
