About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-20
The AirTAC SAIJ200X100-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708N push force at 0.5 MPa. It features a rugged 40mm SUS304 stainless steel rod (code B) for superior corrosion resistance, paired with a PT tapered G3/4 port. This model integrates a rear stroke adjuster that allows you to fine-tune the end position without swapping components.
With a 100mm nominal stroke and a 20mm adjustment range, this cylinder provides a usable travel window of 80-100mm. This built-in adjustability is ideal for product changeovers, letting you dial in the exact retract distance during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and while this SKU omits the magnet, adding an -S variant enables compatibility with AirTAC CMSE reed and DMSE electronic sensors.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-20 Is Used
Heavy Press Tuning
Dial in the exact 80-100mm travel window during heavy press setup to accommodate material thickness variations without changing the cylinder.
Product Changeover
Quickly adjust the retract end-stop on a packaging line when switching between different product sizes, ensuring precise positioning.
Machine Commissioning
Fine-tune the final end position during initial machine build to avoid adding external mechanical stops, streamlining the assembly process.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-20 the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application requires massive thrust, such as 15708N push or 15080N pull at 0.5 MPa. If your force requirements are lower, stepping down to a 160mm bore yields 10053N push force, saving space and air consumption. The adjustable stroke is chosen over a fixed SAI model when precise end-position tuning is necessary at commissioning or when accommodating slight product size variations on a line.
This SAIJ variant uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 100mm, side-load risks are manageable, but the heavy 40mm rod thread handles inherent loads well. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. For true load-holding, consider the SAIL or BSAI series, or an external pilot-operated check valve.
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 SAIJ200BX100-20 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can deliver a maximum push force of 28274N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 20mm. This creates a usable travel window of 80-100mm from the 100mm nominal stroke, allowing you to fine-tune the retract position without replacing the cylinder.
