About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X150-10
The AirTAC MBLCJ20X150-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. A 10mm rear trimmer yields a usable 140-150mm travel window, delivering 157N push and 132N pull at 0.5MPa. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal lock in lubrication for long life.
Unlike the base MBLJ which relies on a fixed rubber bumper, this SKU uses screw-tunable end-of-stroke deceleration to protect the covers during faster moves. The Ø8mm hard-chrome plated carbon-steel rod withstands wear, but at 150mm of travel, external guidance is recommended to prevent side-load bending on the small piston rod. This specific configuration omits the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position sensors.

| Bore size | Ø20 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 140–150 mm (trim 10 mm) |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 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 MBLCJ20X150-10 Is Used
PCB Router Z-Axis
Drives the vertical plunge of a PCB depaneling router, using the 140-150mm stroke window to fine-tune cutting depth while the air cushion softens rapid retraction stops.
Label Applicator Tamp
Applies pressure-sensitive labels to cartons, where the 157N push force securely tamps the film without crushing the package structure.
Textile Yarn Guide
Traverses yarn guides across a weaving loom, benefiting from the cushioned end-caps to reduce vibration and prevent thread snap-back at stroke limits.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X150-10 the Right Cylinder?
Stepping down yields the same 157N force, while stepping up to the 25mm bore provides 245N push at 0.5MPa for heavier demands. Choose the MBLCJ over the MBLJ when your cycle speed requires tuned deceleration rather than a fixed rubber bumper, or select the MBLC if you need fixed standard stroke lengths. Remember the rear adjuster is a travel stop and the cushion only decelerates; neither holds position pneumatically, so use an external lock for drift prevention. Mounting is limited to Basic, FA flange, or LB foot (no SDB or back-cover options). For exact replacement match: 20mm bore, 150mm stroke, 10mm adjust, G1/8 port, PT thread, 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 MBLCJ20X150-10 FAQ
At 0.5MPa it provides 157N push and 132N pull; at 0.7MPa the push increases to 220N. The maximum theoretical force is 32kgf at 1.0MPa. Operating pressure ranges from 0.15 to 1.0MPa.
The rear 10mm stroke adjuster acts as a mechanical travel stop to set your exact 140-150mm end position, while the adjustable air cushion screw-tunes end-of-stroke deceleration. Neither component locks or holds the load pneumatically; the rod will drift without live air pressure.
