About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X600-10
The AirTAC SAIJ125X600-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 6136N of push force at 0.5 MPa. It features a 32mm carbon steel rod and PT tapered G1/2 port. By turning the rear screw, you achieve a 590-600mm usable travel window, allowing precise end-position tuning without swapping out the entire actuator.
This 125mm bore actuator utilizes adjustable air cushions at both ends to decelerate heavy loads smoothly across its 600mm span. Because the rear stopper is a travel limit and not a locking device, it cannot hold loads without live air pressure; for secure load-holding, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X600-10 Is Used
Heavy Material Forming
Dial in the exact 590-600mm retraction point during press setup to accommodate different material thicknesses without external stop blocks.
Large Package Diverting
Fine-tune the actuator end-stop on the fly to handle varying pallet sizes on a 600mm transfer line, ensuring smooth product changeover.
Automated Assembly Stations
Leverage the 6136N push force to seat heavy components, using the 10mm adjustment window to perfect the final seating depth at commissioning.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X600-10 the Right Cylinder?
Select this 125mm bore model when an application demands high thrust combined with on-the-fly end-stop calibration, avoiding the rigid constraints of a fixed-stroke SAI cylinder. If 6136N at 0.5 MPa is excessive, stepping down to an 80mm bore yields 2513N; conversely, a 160mm bore provides 10053N for heavier payloads. To achieve a true ISO 15552 replacement match, verify the 600mm stroke, 10mm adjustment range, PT G1/2 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Since the 600mm stroke is substantial, the 32mm rod and M27x2 thread provide robust support, but an external guide rail is strongly recommended to prevent side-loading damage over long unsupported distances. The standard carbon steel rod handles general industrial environments, operating at speeds of 30-500mm/s.
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 SAIJ125 Adjustable Cylinder SAIJ125X600-10 FAQ
At 0.5 MPa operating pressure, this 125mm bore cylinder provides 6136N of push force and 5734N of pull force. At 0.7 MPa, the push force increases to 8590N.
The rear adjuster screw allows you to shorten the 600mm nominal stroke by up to 10mm, creating a 590-600mm usable travel window. This stopper only limits the travel end and does not lock the load without live air.
