About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X150-10S
The AirTAC MBLCJ50X150-10S is a compact double-acting mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers a push force of 981 N and a pull force of 881 N at 0.5 MPa, making it well-suited for heavier mid-range automation tasks. The built-in magnet (-S) allows for CMSG, DMSG, or EMSG sensor integration to track rod position.
This specific SKU provides a 10 mm rear stroke adjustment, creating a usable travel window of 140 to 150 mm. The riveted aluminum barrel and 20 µm hard-chrome plated carbon-steel rod offer durability, while the adjustable air cushion allows you to tune end-of-stroke deceleration for faster, heavier moves without slamming the end covers. The rear stopper sets the travel end but does not lock the load; external guides are recommended for side-load stability.

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 (Ø50mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 MBLCJ50X150-10S Is Used
Injection Mold Ejection
Provides 981 N of push force at 0.5 MPa to eject plastic parts from mid-sized injection molds, using the 140-150 mm stroke window to accommodate varying mold depths.
Wood Routing Clamp
Secures wooden workpieces against a CNC routing fence. The adjustable air cushion decelerates the 881 N pull force rapidly, preventing marring on softer woods.
Packaging Flap Folder
Folds heavy cardboard carton flaps at high cycle rates. The CMSG reed switch tracks the 150 mm extension, while the cushion absorbs the kinetic energy of the moving rod.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X150-10S the Right Cylinder?
When sizing this 50 mm bore cylinder, consider stepping down to the 40 mm bore if your load requires less force (628 N push at 0.5 MPa), or stepping up to the 63 mm bore for heavy applications needing 1558 N push at 0.5 MPa. Choose the MBLCJ over the MBLJ when you need screw-tunable deceleration rather than a fixed rubber bumper, or the MBLC variant if you prefer a fixed standard stroke without the rear adjuster.
Remember that neither the rear travel stopper nor the adjustable cushion acts as a mechanical lock; the rod will drift without live air pressure, so use an external holding device if position retention is critical. Mounting is limited to Basic, FA (flange), or LB (foot) styles, as this series omits SDB pivot and back-cover options. To match this exact replacement, specify bore 50, stroke 150, adjust code 10, G1/4 port, PT thread, and 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 MBLCJ50X150-10S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides a push force of 981 N and a pull force of 881 N. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The -10S code means you can trim up to 10 mm of travel at the rear stopper, giving a usable stroke window of 140-150 mm. The adjustable air cushion is a separate screw-tunable valve that controls end-of-stroke deceleration; neither the cushion nor the stopper locks the load in place.
