About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-75S
The AirTAC MBLCJ25X150-75S is a compact double-acting mini cylinder featuring a rear travel stopper and tunable air cushions at both ends. The 75mm adjuster creates a usable stroke window of 75-150mm, allowing precise positioning of a 245N push force at 0.5MPa. Its riveted aluminum barrel and 20μm hard-chrome plated Ø10mm carbon-steel rod handle speeds of 30-800mm/s. The built-in -S magnet enables CMSG, DMSG, or EMSG sensor tracking.
Unlike the fixed rubber bumper on an MBLJ, the screw-tunable cushions here decelerate fast moves to protect the end covers. The rear adjuster acts only as a mechanical travel stop, not a load-holding lock. With a 150mm stroke on a small 25mm bore, the overall length extends significantly, making an external guide rail advisable to prevent rod bending under side loads.

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 MBLCJ25X150-75S Is Used
PCB Depaneling Saw Feed
Uses the 75-150mm stroke window to set the exact cut depth on a circular saw blade, while the air cushion smoothly stops the 245N push force to prevent board micro-fracturing.
Label Applicator Tamp
Adjusts the rear stopper to tune the tamp stroke for varying box heights, relying on the end cushions to absorb the rapid extension without bouncing the applicator head.
Textile Yarn Guide
Shifts a yarn guide across a 150mm path; the DMSG solid-state sensor confirms the end position while the cushioning prevents sudden snaps that would break delicate threads.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-75S the Right Cylinder?
For lighter tasks, the 20mm bore yields 157N push at 0.5MPa; for heavier demands, the 32mm bore provides 402N. Choose this MBLCJ over an MBLJ when your cycle speed requires active deceleration rather than a fixed bumper, or over an MBLC if you need a variable end position. Remember that neither the cushion nor the rear stopper locks the load in place—use an external locking device for position holding. Mounting is limited to Basic, FA, or LB; SDB and back-cover options are not available. For exact replacements, match the 25mm bore, 150mm stroke, 75mm adjust code, G1/8 port, PT thread, and the -S 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 MBLCJ25X150-75S FAQ
At 0.5MPa, the push force is 245N and the pull force is 206N. At 0.7MPa, the push force reaches 343N. The maximum theoretical force is 50kgf at 1.0MPa.
The rear adjuster lets you trim up to 75mm of travel, creating a usable stroke window of 75-150mm. This stopper sets the end position but does not lock the load. The separate adjustable air cushion only controls end-of-stroke deceleration.
