About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X25-10S
The AirTAC MBLCJ25X25-10S is a compact double-acting mini cylinder featuring a 25mm bore and a 25mm stroke. It generates 245N of push force at 0.5MPa and 343N at 0.7MPa. A rear stroke adjuster allows you to trim up to 10mm of travel, creating a usable end-position window of 15-25mm. Unlike the base MBLJ, this series replaces the fixed rubber bumper with a screw-tunable ADJUSTABLE AIR CUSHION at both ends, letting you dial in deceleration for faster moves. The -S code indicates a built-in magnet for position detection.
This model uses a G1/8 port and a Ø10mm hard-chrome plated carbon-steel rod. The riveted aluminum barrel and two-way grease-retaining piston seal maintain smooth operation. Remember that the rear adjuster is a travel stop, not a load lock; the cushion only decelerates. Neither feature holds the rod in place without live air pressure. Overall length equals A + 2 x stroke + adjust, and mounting is strictly limited to Basic, FA, or LB.

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 MBLCJ25X25-10S Is Used
PCB Edge Routing Dampening
Deploys the 245N push to hold PCB panels during routing, using the 15-25mm stroke window to fine-tune clamp depth and the air cushion to absorb rapid retraction shocks.
Lab Dispenser Stop
Actuates a 25mm travel stopper for fluid dispensing heads, leveraging the tunable cushion to prevent fluid splashing from sudden end-impacts at high speeds.
Small Parts Ejector
Pushes lightweight plastic components out of an injection mold cavity, using the 10mm rear adjustment to perfectly time the ejection reach without repositioning the whole cylinder.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X25-10S the Right Cylinder?
If you need less force, step down to the 20mm bore (157N push at 0.5MPa); if your payload requires more, step up to the 32mm bore (402N push at 0.5MPa). Choose this MBLCJ over the MBLJ when your cycle speed demands tunable end-cushioning to protect the end covers. Choose the MBLC if you prefer a fixed stroke without the rear adjuster. Because the cushion and the adjuster are not locks, use an external guide or locking device if the load must hold position without air. At 25mm stroke, side-load is minimal, but the 10mm rod still requires axial alignment. Replacement match: 25mm bore, 25mm stroke, 10mm adjust, PT thread, Basic mounting, magnet fitted.
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 MBLCJ25X25-10S FAQ
At 0.5MPa it provides 245N push and 206N pull force; at 0.7MPa push increases to 343N, with a maximum theoretical output of 50kgf at 1.0MPa. The -S code means it has a built-in magnet compatible with AirTAC CMSG (reed), DMSG, and EMSG (electronic) sensor switches.
The 10mm adjustable stroke is a mechanical rear stopper that trims the end position to a 15-25mm usable window. The adjustable air cushion is a separate screw valve that controls end-of-stroke deceleration. Neither holds the load in place without air; they only set travel limits and absorb impact.
