About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-40S
The AirTAC MBLCJ25X150-40S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 40 mm of travel, creating a precise 110-150 mm usable stroke window for varied positioning tasks.
Unlike the fixed rubber bumper found on the base MBLJ, the screw-tunable end cushions here decelerate faster, heavier loads to protect the end covers. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod ensure durability, while the built-in magnet (-S) enables position detection with CMSG reed or DMSG/EMSG electronic switches. Note that the adjuster acts only as a travel stop, not a load-holding lock.

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 MBLCJ25X150-40S Is Used
PCB Edge Router Loader
Depanels printed circuit boards by extending 120 mm into a router fixture, using the 245 N push force to hold the panel while the adjustable cushion prevents impact chatter.
Dispenser Valve Positioning
Trims the rear adjuster to a 110 mm window for applying precise beads of epoxy on electronic housings, relying on the DMSG electronic switch to trigger the valve open.
Textile Fabric Stopper
Acts as a movable end-stop for fabric rolls, where the tunable air cushion decelerates the 150 mm extension smoothly to prevent tearing the synthetic web.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-40S the Right Cylinder?
For applications needing less force, stepping down to a 20 mm bore yields 157 N push at 0.5 MPa; if your payload requires more thrust, stepping up to a 32 mm bore provides 402 N. Choose this MBLCJ over the MBLJ when your moving mass demands tunable end-of-stroke deceleration rather than a simple bumper, or over the MBLC if your cycle requires a variable 110-150 mm end position. The rear stopper and the cushions regulate travel and impact speed, but neither will hold a load statically under pressure loss—use an external lock for that.
Mounting is limited to Basic, FA (flange), or LB (foot) as there is no back-cover or SDB pivot option. The overall length extends by the adjustment amount (A + 2 x stroke + adjust). At 150 mm of travel, the 10 mm rod is susceptible to side-loading; an external guide rail is recommended to prevent bending. Replacement requires matching the 25 mm bore, 150 mm stroke, 40 mm 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 MBLCJ25X150-40S FAQ
At 0.5 MPa it provides 245 N push and 206 N pull. At 0.7 MPa the push force is 343 N. The maximum theoretical force is 50 kgf at the 1.0 MPa operating pressure limit.
The 40 mm adjustable stroke is a rear mechanical stopper that sets your usable travel window between 110 mm and 150 mm. The adjustable air cushion is a separate screw that tunes end-of-stroke deceleration. Neither component locks the load in place.
