About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-75
The AirTAC MBLCJ25X100-75 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 force at 0.5 MPa. The rear stopper trims up to 75 mm of travel, yielding a usable 25-100 mm stroke window for exact positioning. The screw-tunable cushions absorb end-of-stroke kinetic energy, protecting the covers during fast 100 mm moves.
This SKU has no built-in magnet, so it cannot accept CMSG or DMSG position sensors. The riveted rolling-packed barrel and grease-retaining two-way piston seal prevent lubricant washout, while the Ø10 mm carbon-steel rod features 20 µm hard-chrome plating to resist scoring in abrasive settings. The rear adjuster sets the travel end but does not lock the load; external guides are advised for this 100 mm stroke to prevent rod side-loading.

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 MBLCJ25X100-75 Is Used
PCB Router Z-Axis
Adjusts the plunge depth of a spindle over a 25-100 mm window while the air cushion prevents end-cover shock during rapid 245 N retraction.
Dispenser Valve Dosing
Trims the exact stroke for a metering valve, using the 0.15-1.0 MPa pressure range to drive 206 N pull force for consistent adhesive shots.
Textile Tensioner Arm
Guides a fabric web over a 100 mm travel path, relying on the riveted aluminum body and 20 µm chrome rod to resist wear in lint-heavy environments.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-75 the Right Cylinder?
Stepping down, the 20 mm bore yields 157 N push at 0.5 MPa for lighter tasks; stepping up, the 32 mm bore provides 402 N for heavier payloads. Choose this MBLCJ over the MBLJ when your moving mass demands screw-tuned deceleration instead of a fixed rubber bumper, or over the MBLC when you need to trim the 25-100 mm travel window. Remember, the rear adjuster is a travel stop and the cushion only decelerates; neither holds position without live air pressure.
This cylinder is limited to Basic, FA flange, or LB foot mounts; SDB pivot and back-cover options are unavailable. The replacement match is bore 25, stroke 100, adjust 75, G1/8 port, PT thread, basic mount, and no magnet. Because this SKU lacks the -S code, it cannot host a sensor switch.
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 MBLCJ25X100-75 FAQ
At 0.5 MPa, the 25 mm bore provides 245 N push and 206 N pull force. At 0.7 MPa, push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
This specific SKU lacks the -S magnet, so it cannot host CMSG or DMSG sensors. The rear adjuster sets the travel end within the 25-100 mm window, and the air cushion decelerates the piston; neither mechanism locks or holds the load in place without continuous air pressure.
