About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-30
The AirTAC MBLCJ32X450-30 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 402 N of push force at 0.5 MPa through a 12 mm hard-chrome plated rod. The rear stopper allows you to trim up to 30 mm of travel, creating a precise 420-450 mm usable stroke window for varying end positions.
Because this 450 mm stroke approaches the 500 mm maximum limit for a 32 mm bore, the relatively small 12 mm rod requires external guidance to prevent side-load bending. The riveted aluminum barrel and grease-retaining piston seal ensure longevity. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without physical modification.

| Bore size | Ø32 mm |
| Nominal stroke | 450 mm |
| Adjustable window | 420–450 mm (trim 30 mm) |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 MBLCJ32X450-30 Is Used
Textile Loom Beam Indexing
Uses the 420-450 mm adjustable stroke window to precisely set the beam indexing distance, while the air cushion absorbs the kinetic energy of the heavy yarn beam at end-of-stroke.
Printed Circuit Board Conveyor
Transfers PCB racks along a 450 mm path; the tunable cushion prevents sudden jolts that could dislodge delicate components, and the external guide handles the long rod extension.
Packaging Carton Flap Folder
Folds heavy cardboard flaps on a packaging line, using the 402 N push force to overcome board stiffness while the rear adjuster dials in the exact fold depth.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-30 the Right Cylinder?
When sizing this 32 mm bore (402 N push @0.5 MPa), step down to the 25 mm bore if your load requires only 245 N, or step up to the 40 mm bore for 628 N of thrust. Choose this MBLCJ over the MBLJ when your moving mass requires screw-tunable end-of-stroke deceleration to protect the end covers, rather than a fixed rubber bumper. Compared to the MBLC, this model adds the rear travel stopper. Remember that the adjuster is a travel stop, not a lock; it does not hold the load, and the cushion only decelerates. Mounting is limited to Basic, FA, or LB (no SDB or back-cover options). The exact replacement match is a 32 mm bore, 450 mm stroke, 30 mm adjust code, G1/8 PT port, without a magnet.
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 MBLCJ32X450-30 FAQ
At 0.5 MPa it provides 402 N push and 346 N pull force. At 0.7 MPa the push increases to 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The rear adjuster trims up to 30 mm of travel, giving a usable stroke window of 420-450 mm.
No. This specific SKU does not have the -S code, meaning it lacks a built-in magnet. It cannot trigger AirTAC CMSG (reed) or DMSG/EMSG (electronic) switches. You would need the MBLCJ32X450-30S variant for position detection.
