About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X1000-10
The AirTAC SAIJ125X1000-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 990 to 1000 mm usable travel window, allowing you to dial back the retract end-position by up to 10 mm without adding external stops. It delivers 6136 N of push force at 0.5 MPa and 8590 N at 0.7 MPa, making it suited for heavy automation tasks.
This model uses a carbon steel piston rod with an M27x2 thread and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a travel stop to fine-tune deceleration, meaning it will not hold a load safely without live air pressure.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X1000-10 Is Used
Long-Stroke Machining
Dials in the exact 990 to 1000 mm retract position for large fixture clamping without remounting the cylinder.
Product Diverting
Adjusts the stroke end-stop on the fly to handle varying package sizes on a heavy-duty transfer line.
Assembly Line Changeover
Provides a 10 mm tuning window for reconfiguring automated equipment setups during product transitions.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X1000-10 the Right Cylinder?
Choose this 125 mm bore cylinder when your application requires 6136 N of push force at 0.5 MPa. If you need less force, stepping down to an 80 mm bore yields 2513 N; if you need more, stepping up to a 160 mm bore provides 10053 N. The SAIJ125X1000-10 is selected over a fixed-stroke SAI specifically for commissioning flexibility, letting you fine-tune the end position on a 1000 mm stroke by up to 10 mm during product changeovers.
Because this is a 1000 mm stroke, the unsupported rod length requires an external guide to prevent side-load damage, as the 32 mm rod and M27x2 thread can only handle so much leverage. This SKU uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead.
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 SAIJ125X1000-10 FAQ
At 0.5 MPa, it provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel down from 1000 mm to 990 mm. It sets the deceleration point but does not lock or hold the load without live air pressure.
