About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX500-20
The AirTAC SAIJ200X500-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 15708N of push force at 0.5 MPa. Its external adjusting screw allows you to fine-tune the retract end-position, creating a usable travel window of 480-500mm. This eliminates the need to swap cylinders or bolt on external stops during machine commissioning.
This heavy-duty unit features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-500mm/s. It utilizes PT tapered port threads and includes variable air cushions at both ends to decelerate massive loads smoothly. The extruded aluminum barrel integrates sensor grooves on both sides, allowing for straightforward position feedback when paired with compatible switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX500-20 Is Used
Heavy Press Tuning
Dial in the exact 480-500mm end-stop during press setup to accommodate varying material thicknesses without changing the actuator.
Product Changeover
Adjust the retract position on the fly for different pallet sizes on a high-thrust conveyor transfer line.
Large Fixture Alignment
Fine-tune the clamping reach of heavy industrial fixtures during initial commissioning to ensure perfect alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX500-20 the Right Cylinder?
Choose this 200mm bore actuator when an application demands extreme thrust, such as 15708N push or 15080N pull at 0.5 MPa, alongside precise end-stop tuning. If your setup requires less force, stepping down to a 160mm bore yields 10053N of push force, which may better suit mid-heavy fixtures without oversizing. The adjustable 480-500mm window is ideal for product changeovers, whereas a fixed-stroke SAI cylinder is preferable if the end position never varies.
Because the 500mm stroke is substantial, the 40mm rod diameter requires external guiding to prevent excessive side-loading and premature seal wear. Remember that the rear adjuster functions strictly as a travel stop, not a locking device; it cannot hold a load without continuous air pressure. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. This model uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ200BX500-20 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 500mm stroke by up to 20mm, providing a usable travel window of 480-500mm. It only sets the end position and does not lock the load without live air pressure.
