About the Airtac SAIJ50 Adjustable Cylinder SAIJ50X600-50
The AirTAC SAIJ50X600-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 550-600 mm usable travel window, allowing you to dial back the 600 mm nominal stroke by up to 50 mm during commissioning. In the 50 mm bore class, it delivers 982 N of push thrust and 825 N of pull thrust at 0.5 MPa.
This extruded aluminum barrel design includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, though this non-magnet SKU requires adding a -S piston for detection. The M16x1.5 rod thread and 30 mm cushions handle variable end-deceleration. Remember that the adjuster acts as a travel stop, not a lock; it cannot hold loads without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50X600-50 Is Used
Variable End-Stop Positioning
Set precise 550 to 600 mm travel endpoints on a conveyor sorting mechanism to handle different package sizes without mechanical rebuilds.
Machine Changeover
Dial in the exact retraction stop during product format changes, using the 50 mm adjustment screw to fine-tune the tooling position rapidly.
Assembly Press Tuning
Adjust the effective stroke on an assembly press to compensate for material thickness variations, ensuring consistent clamping force.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50X600-50 the Right Cylinder?
Choose this 50 mm bore when 982 N push force at 0.5 MPa is sufficient, stepping down from a 63 mm bore (1559 N) to save air volume, or up from a 40 mm bore (628 N) for higher work output. The 50 mm adjustment range is ideal for product changeovers on a packaging line, letting you fine-tune the end position without swapping cylinders or adding external stops. For load-holding without live air, select a SAIL or BSAI cylinder instead. As a dimensionally interchangeable ISO 15552 unit, it matches standard mounting footprints using PT tapered G1/4 ports and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 600 mm stroke is long and unsupported, an external guide is recommended to prevent rod side-loading.
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 SAIJ50 Adjustable Cylinder SAIJ50X600-50 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push thrust and 825 N of pull thrust. At the maximum 1.0 MPa pressure, it achieves up to 200 kgf.
The rear adjuster screw lets you shorten the 600 mm nominal stroke by up to 50 mm, creating a 550-600 mm usable travel window. It functions as a mechanical stop to fine-tune end positions and does not lock the load without live air.
