About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X225-100
The AirTAC MBLCJ40X225-100 is a compact double-acting mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 100 mm of travel, creating a usable extension window of 125 to 225 mm. This is ideal for applications requiring precise end-position tuning without swapping the entire actuator. The riveted aluminum barrel and 20 µm hard-chrome plated carbon-steel rod ensure durability in tight spaces.
Unlike the fixed rubber bumper found on the MBLJ series, this model uses screw-tunable pneumatic cushioning to decelerate heavy loads smoothly before the end of stroke. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The G1/4 port and M12x1.25 rod-end thread are standard for this 40 mm bore. The rear adjuster acts purely as a mechanical travel stop and does not lock or hold the load in place.

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X225-100 Is Used
Packaging Conveyor Diverter
Pushes heavy cartons at 628 N force, using the 125-225 mm stroke window to tune the diverter arm reach precisely without moving the mounting block.
Woodworking Feed Stop
Acts as an adjustable end-stop for a moving timber carriage, relying on the dual air cushions to absorb the 880 N impact force at 0.7 MPa without damaging the end covers.
Textile Loom Tensioner
Regulates fabric tension in a loom, using the 100 mm rear stroke adjustment to fine-tune the tensioning roller position while handling high dynamic loads.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X225-100 the Right Cylinder?
Select this 40 mm bore when you need substantial push force (628 N at 0.5 MPa) with fine end-position tuning. If your load is lighter, stepping down to the 32 mm bore reduces force to 402 N push while saving space. For heavier dynamics, stepping up to the 50 mm bore provides 981 N push. Choose the MBLCJ over the MBLJ when your moving mass requires adjustable end-of-stroke deceleration to protect the end covers, or over the MBLC if you need to trim the 225 mm stroke down to 125 mm. The rear stopper sets the travel end but is not a lock; the air cushion only decelerates, so an external locking device is required to hold position without live air.
Mounting is limited to Basic, FA (flange), or LB (foot) styles; no SDB pivot or back-cover options exist for this series. The overall length extends by the 100 mm adjuster dimension. This SKU uses a default PT tapered port thread and has no -S magnet, so it cannot accept electronic or reed switches. To replace this actuator, match the 40 mm bore, 225 mm stroke, 100 mm adjust code, PT thread, and non-magnet configuration. Because the stroke is 225 mm, ensure external guidance is used to prevent side-load bending on the Ø16 mm rod.
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 MBLCJ40X225-100 FAQ
At 0.5 MPa it provides 628 N push and 528 N pull force. At 0.7 MPa the push force is 880 N, with a maximum theoretical output of 128 kgf at 1.0 MPa. The 100 mm rear adjuster allows you to trim the 225 mm stroke down to a minimum usable stroke of 125 mm.
This specific SKU does not have a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. Additionally, the adjustable air cushion only regulates end-of-stroke deceleration, and the rear adjuster is a travel stop; neither component locks or holds the load in place without continuous air pressure.
