About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-40S
The AirTAC MBLCJ40X150-40S is a compact double-acting mini cylinder featuring a single Ø16mm carbon-steel rod and a riveted aluminum barrel. It generates 628N of push force and 528N of pull force at 0.5MPa. A rear travel stopper lets you trim up to 40mm of rearward motion, creating a usable stroke window of 110-150mm for precise positioning.
Unlike the fixed rubber bumper on an MBLJ, this model uses a screw-tunable adjustable air cushion at both ends to decelerate heavier moving masses before contact. The 20µm hard-chrome plating on the rod resists scuffing, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. The built-in magnet (-S) supports CMSG reed and DMSG/EMSG electronic sensors for position detection.

| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø40 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 110–150 mm (trim 40 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 MBLCJ40X150-40S Is Used
Injection Mold Extraction
Provides 628N of push to positively eject plastic parts from mold cavities, using the 110-150mm window to dial in the exact ejection reach without moving the cylinder mount.
Printed Circuit Board Pressing
Applies controlled 528N pull force to seat connectors onto PCBs, using the tunable air cushion to prevent impact damage to delicate traces during the 150mm travel.
Textile Beam Indexing
Shifts heavy warp beams into loom position using the full stroke, relying on the adjustable rear stopper to halt the 40mm over-travel and lock the beam alignment mechanically.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-40S the Right Cylinder?
If 628N is too much force, step down to the 32mm bore offering 402N push at 0.5MPa; if you need more power, step up to the 50mm bore providing 981N. Choose this MBLCJ over the MBLJ when your dynamic loads require tuned end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need that 110-150mm adjustable travel window. Remember, the rear stopper sets the end position and the cushion only decelerates; neither holds the load, so use an external guide for side-load protection.
For exact replacement matching, verify the 40mm bore, 150mm nominal stroke, 40mm adjust code, G1/4 port, default PT thread, and the -S magnet. Mounting is limited to Basic, FA flange, or LB foot styles; SDB pivot and back-cover options are not available on this series.
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 MBLCJ40X150-40S FAQ
At 0.5MPa it provides 628N push and 528N pull. At 0.7MPa the push increases to 880N. The maximum theoretical force is 128kgf at 1.0MPa, with a proof pressure of 1.5MPa.
The 40mm adjustable stroke is a mechanical rear stopper that physically limits travel to a 110-150mm window. The adjustable air cushion is a screw-tunable valve that regulates exhaust air to decelerate the piston near the end covers; neither system locks or holds the load in place.
