About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-50

The AirTAC SAIJ200X800-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 750 to 800 mm. Built with a robust 40 mm carbon steel rod and an M36x2 thread, it delivers a substantial 15080 N pull force at 0.5 MPa. This size utilizes a G3/4 port and operates at speeds of 30-500 mm/s.

Because the adjuster acts purely as a mechanical stop, it cannot hold a load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet, meaning CMSE or DMSE switches cannot be used without adding the -S option. Mounting options are restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Heavy Assembly Press

Use the massive 15080 N pull force to draw components together, adjusting the final position by up to 50 mm for perfect alignment.

Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-50 the Right Cylinder?

If you need less force, stepping down to a 160 mm bore provides 9425 N of pull force at 0.5 MPa. For true load-holding without continuous air pressure, you must look to the SAIL or BSAI series, as the SAIJ adjuster is only a travel stop.

With an 800 mm stroke, the 40 mm rod is subject to significant side loads if the load is unsupported. An external guide is strongly recommended to prevent rod binding. This model is dimensionally interchangeable with ISO 15552 cylinders, configured with a PT tapered port, carbon steel rod, and no magnet.

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 SAIJ200X800-50 FAQ

At the maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf.

A rear screw stopper lets you shorten the nominal 800 mm stroke by up to 50 mm, creating a usable travel window of 750 to 800 mm. This stopper only sets the end position and does not lock the load without live air.
