About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-75
The AirTAC MBLCJ40X150-75 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 75 mm of travel, creating a precise usable stroke window of 75 to 150 mm for varying machine spacing requirements. A G1/4 port and Ø16 carbon-steel rod handle the mid-range pneumatic demands effortlessly.
Unlike the fixed rubber bumper found on the base MBLJ series, this model uses screw-tunable end-of-stroke deceleration to absorb kinetic energy, protecting the end covers during faster cycles. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal prevent lubricant washout, extending operational life. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensing. The rear travel stopper sets the end position; it is not a mechanical lock and will not hold a load without live air pressure.

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 MBLCJ40X150-75 Is Used
Spindle Loaders
Positions raw bar stock into CNC lathe collets. The 628 N push force handles heavy steel bars, while the 75-150 mm stroke window dials in exact insertion depth without reprogramming the PLC.
Packaging Crimpers
Seals corrugated carton flaps. The adjustable air cushion slows the 16 mm rod before the end cap, preventing the crimping head from smashing the cardboard during high-speed packaging runs.
Woodworking Clamps
Holds cabinet door panels steady during routing. The PT-threaded G1/4 port delivers the 528 N pull force needed to resist router vibration, and the rear stopper sets exact clamp depth.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-75 the Right Cylinder?
When sizing this 40 mm bore actuator, consider stepping down to the 32 mm bore (402 N push @0.5 MPa) for lighter pick-and-place tasks, or stepping up to the 50 mm bore (981 N push @0.5 MPa) if you need to overcome heavy friction or move larger masses. Choose the MBLCJ over the MBLJ when your cycle speeds demand adjustable end-cover protection rather than a fixed rubber bumper, or over the MBLC if your machine design requires a variable end position rather than a fixed stroke length. To match this exact replacement, confirm the 40 mm bore, 150 mm nominal stroke, 75 mm adjuster code, G1/4 port, PT thread form, Basic/FA/LB mounting, and the absence of a magnet. Mounting is restricted to Basic, FA flange, or LB foot; there is no SDB pivot or back-cover option available for this body. Because the rear adjuster is a travel stop and the cushion only decelerates, any position-holding application requires an external locking device. The overall length equals A + 2 x 150 + 75; verify your axial space constraints.
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 MBLCJ40X150-75 FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N 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 standard stroke limit for this bore is 500 mm, so the 150 mm stroke is well within standard limits.
No to both. This SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the rear stroke adjuster is a travel stop that sets the end position, and the adjustable air cushion only decelerates the piston. Neither component is a mechanical lock, so the rod will drift if air pressure is removed; use an external locking device for position holding.
