About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-30
The AirTAC MBLCJ40X450-30 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. A G1/4 port feeds the Ø16 hard-chrome rod, generating 628 N push and 528 N pull at 0.5 MPa. The 30 mm rear trimmer yields a usable 420-450 mm travel window, ideal for long-transfer positioning.
Twin screw-tunable cushions absorb kinetic energy at each stroke end, protecting the covers where a fixed bumper would fail. This SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. Because the 450 mm stroke approaches the 500 mm limit, the small 16 mm rod needs an external guide to prevent side-load bending.

| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø40 mm |
| Nominal stroke | 450 mm |
| Adjustable window | 420–450 mm (trim 30 mm) |
| Acting type | Double acting |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 MBLCJ40X450-30 Is Used
Textile Tentering Frame
Drives the 450 mm chain tensioning gate in fabric stretching, using the 628 N force to maintain uniform weave tension during heat setting.
Pallet Conveyor Diverter
Tunes end-deceleration to softly pivot heavy wood pallets onto a side lane without jarring the bearings over the long 420-450 mm travel.
Board Trimming Saw
Feeds a cross-cut saw across a 450 mm span, where the adjustable cushion halts the blade smoothly at the end of the cut.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X450-30 the Right Cylinder?
For lighter 343 N push tasks, step down to the 32 mm bore; for heavier 981 N loads, step up to the 50 mm bore. Choose this MBLCJ over the MBLJ for heavy deceleration control, or the MBLC if fixed travel is acceptable. The rear stopper sets the 420-450 mm end position but does not hold the load—use an external lock. Mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. To replace: match 40 mm bore, 450 mm stroke, 30 mm adjust, G1/4 port, PT thread, and no 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 MBLCJ40X450-30 FAQ
At 0.5 MPa it delivers 628 N push and 528 N pull; at 0.7 MPa it pushes 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The rear screw physically stops the piston to set your 420-450 mm travel window, while the adjustable air cushion only regulates end-of-stroke deceleration. Neither mechanism locks or holds the load in place.
