About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-75S
The AirTAC SAIJ200X130-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 130 mm travel by up to 75 mm, yielding a highly flexible 55-130 mm usable end-position window. It delivers immense thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suitable for heavy-duty press operations. This variant incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a built-in magnet for position sensing.
The extruded aluminum barrel features sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE solid-state switches without requiring additional brackets. Because the rear screw acts purely as a mechanical stop to set the travel end, it does not hold the load without live air pressure. For load-holding requirements without continuous pneumatic supply, consider the related SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-75S Is Used
Heavy Press Tuning
Fine-tune the 55-130 mm travel window during heavy press commissioning to achieve exact material deformation without swapping physical cylinder bodies.
Product Size Changeover
Rapidly adapt the end-stop position on automated lines processing varying product sizes, utilizing the 75 mm adjustment range to accommodate different heights.
High-Force Assembly
Leverage the 15708 N push force at 0.5 MPa for intense joining operations, using the rear screw to dial in the perfect clamping depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-75S the Right Cylinder?
Select this 200 mm bore cylinder when your application requires extreme force, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The adjustable stroke is ideal for machine setups requiring precise end-position tuning during commissioning or product changeover, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. Ensure your fluid supply is filtered to 40 um and operates within the 0.15-1.0 MPa pressure range.
When integrating this model, note the PT (tapered) port threads and the G3/4 port size. It supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Although the 130 mm nominal stroke is below the 300 mm side-load threshold, the substantial 40 mm rod diameter and M36x2 thread handle high stresses well. For true fail-safe load holding without live air, specify an external pilot-operated check valve or a SAIL locking cylinder instead of relying on the adjuster.

- ✓ 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 SAIJ200AX130-75S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. It can reach a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the 130 mm nominal stroke by up to 75 mm, creating a 55-130 mm usable travel window. This stop only sets the end position and does not lock or hold the load without live air pressure.
