About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-30
The AirTAC MBLCJ50X225-30 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. You can trim up to 30mm of travel at the rear, creating a usable stroke window of 195-225mm. Driven by a Ø16 carbon-steel rod, it delivers 981N push and 881N pull force at 0.5 MPa, making it ideal for heavier mid-range automation tasks.
This model uses a riveted rolling-packed aluminum barrel and a grease-retaining piston seal for long service life. The screw-tunable air cushion decelerates heavy loads near the stroke ends, protecting the end covers better than a fixed rubber bumper. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. The rear adjuster acts as a travel stop, not a mechanical lock.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-30 Is Used
Pallet Diverters
With 981N push force at 0.5 MPa and a 225mm stroke, this cylinder cleanly diverts heavy wooden pallets on packaging lines, using the adjustable cushion to stop the load smoothly.
Press Stamper
The 195-225mm adjustable window provides exact travel for a secondary metal press stamper, while the tunable air cushion protects the tooling from heavy end-impact shock.
Carton Flap Folder
Delivers 881N pull force to fold heavy cardboard flaps on high-speed case erectors, relying on the cushion needle valve to brake the rod before it strikes the cover.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-30 the Right Cylinder?
Stepping down to the 40mm bore drops output to 628N push at 0.5 MPa, while stepping up to the 63mm bore increases it to 1558N. Choose the MBLCJ over the MBLJ when your moving mass requires tunable end-deceleration rather than a fixed bumper, or the MBLC if you need a fixed 225mm stroke without the rear adjuster. Remember that neither the cushion nor the adjuster holds the load in place; use an external lock for position holding. Mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. To replace this SKU exactly, match the 50mm bore, 225mm stroke, 30mm adjust code, G1/4 PT thread, and no-magnet configuration.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Adjustable window fits your end position
- ✓ Adjuster is a travel stop, not a lock
- ✓ Magnet (S) for sensors?
- ✓ Side load — add a guide on long strokes
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear stopper for the end position (a travel stop, not a lock).
- check Avoid side load; add an external guide on long strokes.
- check Mounting: Basic / FA flange / LB foot (no SDB, no back-cover code).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X225-30 FAQ
At 0.5 MPa, this 50mm bore cylinder provides 981N push and 881N pull force. At 0.7 MPa, the push force increases to 1374N. The maximum theoretical force is 200 kgf at 1.0 MPa operating pressure.
The rear adjuster lets you trim the stroke by 30mm (a 195-225mm usable window), acting as a mechanical travel stop. The adjustable air cushion uses a screw needle valve to tune end-of-stroke deceleration. Neither holds the load; the rod drifts without live air.
