Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-75S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-75S
The AirTAC SAIJ200X75-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, generating 15708N of push force and 15080N of pull force at 0.5 MPa. Because this specific SKU carries a 75 mm adjustment code on a 75 mm nominal stroke, you can dial the effective travel all the way back to a 0-75 mm window. This extreme adjustability allows you to set exact retract end-positions at commissioning without swapping out the entire actuator.
This model features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses PT tapered ports sized G3/4 and operates at speeds between 30-500 mm/s. The rear screw acts purely as a travel stop for end-position tuning, not as a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-75S Is Used
Heavy Press Tuning
Dial in the exact 0-75 mm retract position for high-tonnage pressing operations without adding external mechanical stops.
Product Changeover
Quickly readjust the stroke window on a packaging line when transitioning between differently sized large-format products.
Robotic End Effectors
Utilize the 15708N push force and SUS304 rod for robust, corrosion-resistant actuation in heavy automated tooling setups.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-75S the Right Cylinder?
Choose this 200 mm bore actuator when an application demands extreme force, requiring up to 3204 kgf at 1.0 MPa. If you need less thrust, stepping down to a 160 mm bore yields 10053N of push force at 0.5 MPa, which might better suit medium-heavy loads. The adjustable stroke is selected over a fixed SAI cylinder when a machine requires variable end-stops or frequent product-size changeovers. To match this ISO 15552 dimensionally interchangeable cylinder for a replacement, verify the 75 mm stroke, 75 mm adjustment, G3/4 PT port, and the -S magnet. For true load-holding without live air pressure, you must integrate an external rod lock or look to the SAIL or BSAI series, as the SAIJ adjuster cannot hold a load.
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 SAIJ200BX75-75S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa pressure, it can generate up to 3204 kgf.
The rear adjuster screw lets you trim the effective travel within a 0-75 mm window from the nominal 75 mm stroke. This stopper fine-tunes the end position during setup but does not lock or hold the load without continuous air pressure.
