Airtac SAIJ50 Adjustable Cylinder SAIJ50AX800-10
The AirTAC Airtac SAIJ50 Adjustable Cylinder SAIJ50AX800-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 800mm stroke, G1/4 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 SAIJ50 Adjustable Cylinder SAIJ50AX800-10
The AirTAC SAIJ50X800-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 790 and 800 mm. It delivers a push thrust of 982 N at 0.5 MPa, making it well-suited for moderate-load automation. The extruded aluminum barrel includes sensor grooves on both sides, and the rod is constructed from SUS420J2 stainless steel for enhanced corrosion resistance.
This model uses PT tapered port threads and operates reliably at speeds from 30 to 800 mm/s. The rear adjuster acts purely as a mechanical stop to dial in the exact retract position during commissioning without adding external stops. It is important to note that this adjuster is not a locking device; the cylinder cannot hold a load without live air pressure, so applications requiring true load-holding should utilize an external pilot-operated check valve or a SAIL series cylinder.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX800-10 Is Used
Machine Setup Tuning
Dial in the exact 790 to 800 mm retract position during initial commissioning without machining custom external stopper blocks.
Product Changeover
Quickly adapt the end-stop distance by up to 10 mm on a packaging line when handling slightly different product lengths.
Long-Stroke Assembly
Execute 800 mm linear extensions for component placement, using the rear screw to absorb final position tolerances safely.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX800-10 the Right Cylinder?
Choose this 50 mm bore when you need a thrust output of 982 N at 0.5 MPa, which sits neatly below the 63 mm bore's 1559 N capacity. The 10 mm adjustment range is ideal for applications requiring precise end-position tuning over a long 800 mm stroke. Because the stroke is 800 mm, the 20 mm rod diameter and M16x1.5 rod thread will experience significant leverage forces; an external guide is strongly recommended to prevent side-load damage to the barrel seals.
For an exact ISO 15552 replacement match, verify the 50 mm bore, 800 mm stroke, 10 mm adjustment, PT port thread, and standard non-magnet configuration. The available mounting interface set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR foot and pivot options found on some standard cylinders.

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 SAIJ50 Adjustable Cylinder SAIJ50AX800-10 FAQ
At a 0.5 MPa operating pressure, the 50 mm bore provides a push thrust of 982 N and a pull thrust of 825 N. The maximum push thrust reaches 1767 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from 800 mm down to 790 mm. It only controls the end-of-stroke deceleration and does not lock the load without continuous air pressure.
