About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-20S
The AirTAC SAIJ200X40-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing with 15708N and pulling with 15080N at 0.5 MPa. By integrating a rear adjustment screw, this model allows you to fine-tune the stroke end position during commissioning without bolting on external stops. The SUS420J2 stainless steel rod (option A) provides enhanced corrosion resistance for harsher environments.
This specific SKU provides a usable travel window of 20 to 40 mm, allowing you to dial back the nominal 40 mm stroke by up to 20 mm. It includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches. The extruded aluminum barrel features sensor grooves on both sides, and the unit uses PT tapered G3/4 ports. It supports a speed range of 30-500 mm/s and includes variable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-20S Is Used
Heavy-Duty Press Tuning
Dial in the exact 20-40 mm pressing distance during machine commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the end-stop position on a packaging line when switching between different product sizes, utilizing the 20 mm adjustment range.
Robotic End Effectors
Provide massive 15708N push force at 0.5 MPa for heavy clamping tasks while using the rear screw to fine-tune the retracted position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-20S the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force, such as 15708N push at 0.5 MPa. If you need less thrust, stepping down to a 160 mm bore yields 10053N of push force at the same pressure, which might better suit medium-duty tasks. The adjustable stroke is highly beneficial for product-size changeovers on a line, letting you set variable end-stops on the fly. Because the nominal stroke is 40 mm, you do not need an external guide for side loads, but remember that long unsupported strokes require external guidance.
For ISO 15552 replacement matching, ensure your setup aligns with a 200 mm bore, 40 mm nominal stroke, 20 mm adjustment range, PT G3/4 port, and a magnet for sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR. Note that the rear adjuster acts solely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ200AX40-20S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. It operates at a speed range of 30-500 mm/s and features variable air cushions at both ends to manage heavy deceleration.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back by up to 20 mm. For this SAIJ200X40-20-S model, this creates a usable travel window between 20 and 40 mm, allowing precise end-position tuning without replacing the cylinder.
