About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-20
The AirTAC MBLCJ25X150-20 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers 245 N push and 206 N pull force at 0.5 MPa. The rear stopper allows you to trim up to 20 mm of travel, creating a usable 130-150 mm stroke window for exact end-position tuning.
Unlike the fixed rubber bumper on the MBLJ, this model uses screw-tunable end-of-stroke cushioning to decelerate faster or heavier loads, protecting the end covers. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod enhance durability. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 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 MBLCJ25X150-20 Is Used
PCB Router Z-Axis
Governs the plunge depth of a spindle on a PCB routing machine. The 245 N push force handles the Z-axis mass, while the 130-150 mm adjustable window dials in the exact cutting depth without mechanical spacers.
Label Applicator Wipe
Drives the wipe-down arm on a bottle labeling line. The tunable air cushion slows the 150 mm stroke just before the label contact point, preventing label slippage and ensuring a crease-free application.
Filament Guide Cut
Positions a cutting blade on a 3D filament extrusion line. The rear adjuster sets the precise 130 mm cut length, while the hard-chrome rod resists repetitive friction from the guide carriage.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-20 the Right Cylinder?
For lower force requirements, stepping down to a 20 mm bore yields 157 N push at 0.5 MPa, while moving up to a 32 mm bore provides 402 N push if your payload demands more. Choose this MBLCJ over the MBLJ when you need adjustable end-deceleration rather than a fixed bumper, or over the MBLC if you need the 130-150 mm travel window rather than a fixed 150 mm stroke. Remember that the rear adjuster is a travel stop and the cushion only decelerates; neither holds the load in place without continuous air pressure.
Mounting is limited to Basic, FA (flange), or LB (foot) brackets; this series does not support SDB pivots or back-cover options. When ordering a replacement, verify the 25 mm bore, 150 mm stroke, 20 mm adjust code, G1/8 port, PT thread form, and the absence of the -S magnet. The overall length extends to A + 2 x stroke + adjust, so plan your envelope accordingly.
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 MBLCJ25X150-20 FAQ
At 0.5 MPa, this 25 mm bore cylinder outputs 245 N push and 206 N pull. At 0.7 MPa, the push force is 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. The 150 mm stroke is within the 300 mm maximum standard stroke limit for this bore size.
No, this specific SKU (MBLCJ25X150-20) does not have the -S code, meaning it lacks a built-in magnet and cannot be used with CMSG, DMSG, or EMSG sensor switches. If position detection is required, you must select the MBLCJ25X150-20S variant.
