About the Airtac SAIJ125 Adjustable Cylinder SAIJ125BX600-10
The AirTAC SAIJ125X600-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 6136N of push force at 0.5MPa, utilizing a 32mm SUS304 stainless steel rod and G1/2 PT tapered ports. The integrated -10 adjustment code provides a 590-600mm usable travel window, allowing you to dial in the exact retract position without swapping hardware.
Because the adjuster functions strictly as a mechanical stop and not a lock, live air is required to maintain the load during operation. This extruded aluminum barrel includes sensor grooves on both sides, and the robust 32mm rod thread handles substantial side loads, though a 600mm stroke still necessitates external guiding to prevent rod deflection.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125BX600-10 Is Used
Precision Retract Tuning
Fine-tune the 590-600mm end-of-stroke position during machine commissioning to achieve exact component placement without re-machining hard stops.
Product Size Changeover
Quickly adjust the retract depth by up to 10mm on automated lines handling slightly varying product lengths, minimizing downtime between batches.
Heavy-Duty Positioning
Leverage the 6136N push force at 0.5MPa to move heavy pallets or fixtures, relying on the external adjuster to set the precise stopping point.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125BX600-10 the Right Cylinder?
Select this 125mm bore when 80mm falls short at 2513N or 100mm is insufficient at 3927N, both rated at 0.5MPa. An adjustable stroke is ideal for machine setups requiring precise retract limits during product changeovers, replacing the need for fixed external stops. For load-holding without continuous air pressure, integrate an external pilot-operated check valve or select the SAIL or BSAI series instead. To match this ISO 15552 footprint, specify the 125mm bore, 600mm stroke, 10mm adjustment, G1/2 PT ports, and SUS304 rod material.
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 SAIJ125BX600-10 FAQ
At 0.5MPa operating pressure, this 125mm bore cylinder provides 6136N of push force and 5734N of pull force. It can reach a maximum push force of 11045N at 0.9MPa.
The rear adjuster acts as a mechanical stop that shortens the 600mm nominal stroke by up to 10mm, creating a 590-600mm travel window. It only sets the end position and does not lock the load without live air pressure.
