About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X30-10
The AirTAC MBLCJ40X30-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The 10 mm rear trimmer creates a usable stroke window of 20 to 30 mm, letting you dial in the exact end position. A G1/4 port feeds the Ø16 mm carbon-steel rod.
Unlike the fixed rubber bumper on a standard MBLJ, this model uses screw-tunable deceleration to protect the end covers during high-impact moves. The riveted rolling-packed barrel and grease-retaining piston seal ensure longevity. This SKU lacks a built-in magnet, meaning it cannot accept CMSG, DMSG, or EMSG position sensors.

| Nominal stroke | 30 mm |
| Adjustable window | 20–30 mm (trim 10 mm) |
| Acting type | Double acting |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

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 MBLCJ40X30-10 Is Used
PCB Router Z-Axis
Dials the 20-30 mm plunge depth for a spindle motor, using the tunable cushion to soften stops and protect the 628 N thrust bearings during rapid routing.
Bottle Capper Head
Applies precise downward pressure on aluminum cap dies, with the rear adjuster trimming the final 10 mm to compensate for varying bottle rim heights.
Leather Press Stamper
Drives a 40 mm bore die for embossing thick hides, relying on the adjustable air cushion to absorb the 528 N retraction shock and prevent frame vibration.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X30-10 the Right Cylinder?
If you need less force, the 32 mm bore provides 402 N push at 0.5 MPa, while stepping up to the 50 mm bore yields 981 N for heavier payloads. Choose this MBLCJ over the MBLJ when your cycle speed demands tunable end-of-stroke damping rather than a fixed bumper. Remember, the rear stopper sets travel limits and the cushion only decelerates; neither holds the load, so use an external lock for position holding.
Mounting is limited to Basic, FA flange, or LB foot styles; no SDB pivot or back-cover code applies. For an exact replacement, match the 40 mm bore, 30 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and note the absence of the -S magnet option.
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 MBLCJ40X30-10 FAQ
At 0.5 MPa, the 40 mm bore provides 628 N push and 528 N pull force. At 0.7 MPa, push increases to 880 N. The theoretical maximum force is 128 kgf at 1.0 MPa.
The 10 mm rear adjuster acts as a travel stop, setting your usable stroke window between 20 and 30 mm. The adjustable air cushion separately tunes end-of-stroke deceleration to reduce impact shock. Neither feature locks or holds the load mechanically.
