About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X20-10
The AirTAC MBLCJ25X20-10 is a compact double-acting mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 245 N push and 206 N pull force at 0.5 MPa. The 10 mm rear adjustment lets you trim the nominal 20 mm stroke down to a 10 mm minimum, creating a precise 10-20 mm usable travel window for exact end-positioning.
This model uses a G1/8 port and a Ø10 mm hard-chrome plated carbon steel rod. Unlike the fixed rubber bumper found on the MBLJ series, the screw-tunable end cushions here allow you to dial in deceleration for faster moving loads, protecting the end covers. Note this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG or EMSG position sensors.

| Series | MBL aluminum-barrel mini round cylinder (adjustable stroke) |
| Bore size | Ø25 mm |
| Nominal stroke | 20 mm |
| Adjustable window | 10–20 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 |

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 MBLCJ25X20-10 Is Used
Pick-and-Place Nozzle Lift
Drives the vertical Z-axis stroke on a PCB assembly nozzle, using the 10-20 mm window to dial in exact component placement height while the air cushion halts the 245 N thrust smoothly.
Micro-Clamp Actuation
Actuates a small pneumatic clamp in electronics packaging, where the adjustable end cushion softens the impact of rapid 20 mm clamping moves on delicate silicon wafers.
Label Applicator Tamp
Powers the short tamp stroke on a bottle labeling head, using the rear stopper to set a 15 mm precise label contact distance without bouncing the applicator plate.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X20-10 the Right Cylinder?
Choose this 25 mm bore when you need 245 N of thrust at 0.5 MPa within a tight 10-20 mm travel window. If your payload is lighter, step down to the 20 mm bore (157 N push); for heavier drives, step up to the 32 mm bore (402 N push). Compared to the fixed-stroke MBLC, this cylinder grants rear travel trimming, and over the MBLJ it adds tunable pneumatic damping instead of a rubber bumper.
Remember the rear adjuster acts only as a mechanical travel stop, not a lock, and the air cushion strictly decelerates without holding position. Mounting is limited to Basic, FA flange, or LB foot styles, with no SDB pivot or back-cover options. To replace this unit, match the 25 mm bore, 20 mm stroke, 10 mm adjust code, G1/8 PT thread, and confirm no magnet is required.
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 MBLCJ25X20-10 FAQ
At 0.5 MPa it provides 245 N push and 206 N pull force; at 0.7 MPa the push increases to 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. The 10 mm rear adjuster allows you to trim the 20 mm stroke down to a 10 mm minimum, yielding a 10-20 mm usable travel window.
This specific SKU lacks the -S code, so it has no internal magnet and cannot accept CMSG, DMSG or EMSG position switches. Additionally, the adjustable air cushion only tunes end-of-stroke deceleration and the rear adjuster is merely a travel stop; neither feature locks or holds the load in place.
