About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-10S
The AirTAC MBLCJ25X175-10S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 245 N of push force at 0.5 MPa. The rear stopper allows you to trim up to 10 mm of travel, creating a precise 165-175 mm usable stroke window for exact end-positioning.
Unlike the fixed rubber bumper found on the base MBLJ series, the screw-tunable cushion valves on this unit let you dial in end-of-stroke deceleration for faster, heavier moves without slamming the end covers. The built-in magnet (-S) enables rod position detection using AirTAC CMSG reed or DMSG/EMSG electronic switches. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod ensure durable, low-friction operation.

| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø25 mm |
| Nominal stroke | 175 mm |
| Adjustable window | 165–175 mm (trim 10 mm) |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |

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 MBLCJ25X175-10S Is Used
PCB Depaneling Saw
Provides 245 N push to feed a circular saw blade through router material, using the 165-175 mm adjustable window to set the exact cut depth.
Dispenser Valve Dosing
Uses the adjustable air cushion to decelerate the 175 mm stroke, preventing fluid splashing when opening a high-viscosity adhesive valve.
Textile Loom Tensioner
Shifts a yarn guide rod precisely within the 165-175 mm range, relying on the DMSG electronic sensor to confirm thread positioning.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X175-10S the Right Cylinder?
Choose this 25 mm bore when you need 245 N push at 0.5 MPa over a 175 mm stroke with fine-tuned deceleration. If your application requires less force, the 20 mm bore provides 157 N push. If you need more power, the 32 mm bore offers 402 N push. For exact replacements, match the 25 mm bore, 175 mm stroke, 10 mm adjust code, G1/8 port, PT thread, and the -S magnet.
Remember that the rear adjuster is a travel stop, not a mechanical lock; it sets the end position but will not hold a load without live air pressure. Mounting is limited to Basic, FA, or LB styles, as no SDB pivot or back-cover options exist for the MBLCJ series. Because the stroke is 175 mm, the 10 mm piston rod is susceptible to side-load bending; always use an external guide rail to prevent cylinder damage.
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 MBLCJ25X175-10S FAQ
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The adjustable stroke uses a rear stopper to mechanically trim the travel window down to 165-175 mm. The adjustable air cushion uses needle valves to tune end-of-stroke deceleration speed. Neither feature locks the rod in place; holding a load requires continuous air pressure.
