About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X400-10
The AirTAC MBLCJ40X400-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 628 N push and 528 N pull at 0.5 MPa. The rear stopper allows you to trim up to 10 mm of travel, creating a usable 390-400 mm stroke window for precise end positioning.
Unlike the fixed rubber bumper on an MBLJ, the adjustable air cushion lets you screw-tune end-of-stroke deceleration to protect the end covers during fast 400 mm moves. The riveted rolling-packed barrel and grease-retaining piston seal keep operating friction low. Note this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X400-10 Is Used
Textile Loom Beater
Drives the 400 mm beater motion on a weaving loom, using the tunable air cushion to softly absorb the 628 N deceleration impact at high cycle rates without damaging the end covers.
Packaging Flap Folder
Folds heavy corrugated carton flaps where the 10 mm rear stroke trim perfectly dials in the exact 390-400 mm closing window for varying box sizes.
Bottling Line Diverter
Actuates a heavy diverter arm on a glass bottling line, relying on the 528 N pull force to reliably retract the 16 mm rod against conveyor vibration.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X400-10 the Right Cylinder?
If you need less force, the 32 mm bore yields 402 N push at 0.5 MPa; stepping up to the 50 mm bore provides 981 N. Choose this MBLCJ over the MBLJ when your moving load requires tunable end-of-stroke deceleration rather than a fixed bumper. The rear adjuster sets a travel stop, not a lock; the cushion only decelerates, so use an external locking device to hold a load. Mounting is limited to Basic, FA, or LB; no SDB pivot or back-cover code is available. For a drop-in replacement, match the 40 mm bore, 400 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and no magnet. Because the 400 mm stroke is long relative to the 16 mm rod, always use an external guide to prevent rod bending and seal wear.
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 MBLCJ40X400-10 FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The rear adjuster is a mechanical travel stop that trims the stroke by 10 mm (usable window 390-400 mm), but it does not lock the load in place. The adjustable air cushion is a separate screw-tunable feature that controls end-of-stroke deceleration to prevent impact damage.
