About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-50
The AirTAC SAIJ200X130-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 80 to 130 mm, letting you dial back the nominal 130 mm stroke by up to 50 mm during commissioning without adding external stops. It delivers massive thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa.
This heavy-duty bore uses a 40 mm carbon steel rod and a robust M36x2 rod thread to manage high side loads, though long unsupported strokes still require an external guide. The extruded aluminum barrel includes sensor grooves on both sides, and the rod is fitted with a SUS420J2 stainless steel (A) option for enhanced corrosion resistance.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-50 Is Used
Heavy Press End-Position Tuning
Dial in the exact 80-130 mm travel distance during machine commissioning to accommodate varying material thicknesses without swapping out the entire cylinder.
Product-Size Changeovers
Quickly adjust the retract end-stop on a production line to handle different product dimensions, leveraging the 50 mm adjustment range to maintain precise positioning.
Large Assembly Actuation
Provide up to 28274 N of push force at 0.9 MPa for heavy assembly operations while fine-tuning the stroke to prevent overtravel damage to the tooling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-50 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force, pushing up to 21991 N at 0.7 MPa. If your setup can operate efficiently on less thrust, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which may save space and air consumption. The SAIJ200X130-50 is selected specifically when you need precise variable end-stops for product changeovers rather than a fixed-stroke SAI cylinder.
Remember that the rear adjuster acts only as a travel stop to decelerate the load, not as a lock. A plain SAIJ cylinder will not hold its position or load without live air pressure. For true fail-safe load-holding, consider an external rod lock, a pilot-operated check valve, or related AirTAC types like the SAIL or BSAI. This model features PT tapered ports and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX130-50 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum operating pressure of 1.0 MPa, it delivers a maximum push force of 28274 N.
The rear adjusting screw allows you to shorten the effective travel from the nominal 130 mm down to 80 mm, creating an 80-130 mm usable window. This stopper fine-tunes the end position at commissioning but does not lock the load without live air pressure.
