About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-10S
The AirTAC MBLCJ25X150-10S 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 and 206 N of pull force at 0.5 MPa. The built-in magnet (-S) supports CMSG reed and DMSG or EMSG electronic sensors for position detection. The 10 mm rear adjuster creates a usable travel window of 140 to 150 mm, letting you fine-tune the end position without mechanical shims.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable pneumatic cushioning to decelerate heavier or faster moving loads smoothly, protecting the end covers. The riveted rolling-packed aluminum barrel and 20 µm hard-chrome plated carbon-steel rod withstand harsh environments. Remember the rear stopper sets the travel end but does not lock the load; external guides are recommended for this 150 mm stroke to prevent rod bending side loads.

| 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 MBLCJ25X150-10S Is Used
PCB Routing Conveyor
Positions edge guides on a PCB routing conveyor using the 140-150 mm adjustable window, while the tunable air cushion decelerates the 245 N push to prevent board snapping at stroke end.
Textile Tensioner
Trims a fabric tensioning arm in a textile loom; the 10 mm rear stopper dials in exact material sag without shims, and the cushion absorbs the rapid 150 mm retraction.
Bottle Divert Gate
Actuates a divert gate on a packaging line where the DMSG solid-state sensor confirms the 150 mm extension, allowing high-speed sorting without end-cover impact damage.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X150-10S the Right Cylinder?
Choose this 25 mm bore when you need 245 N push force at 0.5 MPa. If your application requires less force, step down to the 20 mm bore which provides 157 N push. If you need more power, step up to the 32 mm bore yielding 402 N. The MBLCJ is preferred over the MBLJ when your cycle speeds demand tunable end-cushioning rather than a fixed bumper. It differs from the MBLC by offering the rear stroke adjuster.
The 10 mm adjustable stroke sets a 140-150 mm usable window. The adjuster is a travel stop, not a load lock; the cushion only decelerates and neither holds position without live air. Mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. For exact replacement matching, verify bore 25 mm, stroke 150 mm, adjust 10 mm, 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 MBLCJ25X150-10S FAQ
At 0.5 MPa it 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.
The 10 mm rear adjuster mechanically trims the travel end to a 140-150 mm window, acting as a physical stop. The adjustable air cushion uses a screw to tune pneumatic deceleration near the stroke end. Neither holds the load in place without live air.
