About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-50
The AirTAC MBLCJ25X200-50 is a compact double-acting mini cylinder featuring a rear adjustable stroke and an adjustable air cushion at both ends. It delivers 245 N push and 206 N pull force at 0.5 MPa via a G1/8 port. The rear stopper allows you to trim up to 50 mm of travel, creating a usable 150-200 mm stroke window ideal for varying machine format changes.
Unlike the base MBLJ with its fixed rubber bumper, this model uses screw-tunable air cushioning to decelerate heavier loads smoothly at the stroke ends, protecting the end covers. Note that this specific SKU lacks a built-in magnet (-S), meaning it cannot accept CMSG, DMSG, or EMSG position sensors. The adjuster is strictly a travel stop, not a lock; it sets the end position but does not hold the load pneumatically. Its riveted aluminum barrel and 20 µm hard-chrome plated Ø10 mm carbon-steel rod ensure reliable sealing and durability.

| 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 MBLCJ25X200-50 Is Used
Packaging Conveyor Diverter
Provides 245 N of push force to actuate a diverter gate on a continuous flow packaging line, using the 150-200 mm stroke window to adapt to varying carton widths.
PCB Depanelling Press
Utilizes the adjustable air cushion to softly decelerate the 206 N pull force during retraction, preventing sudden impacts that could crack fragile printed circuit boards.
Textile Tensioning Arm
Employs the 200 mm travel to maintain consistent fabric tension on a loom, relying on the riveted aluminum body for compactness in tight machine frames.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-50 the Right Cylinder?
If sizing around this 25 mm bore, stepping down to the 20 mm bore yields 157 N push force at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N. Choose this MBLCJ over the MBLJ when your application speed requires tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC if you need on-machine stroke length flexibility. Remember that neither the rear stroke adjuster nor the air cushion acts as a load-holding lock; drift will occur without live air pressure, so use an external guide for side loads. Mounting is limited to Basic, FA, or LB styles (no SDB or back-cover options). For an exact replacement, match the 25 mm bore, 200 mm stroke, 50 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 MBLCJ25X200-50 FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No, this specific SKU lacks the built-in magnet (-S code), so it cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches. You would need the MBLCJ25X200-50S variant for reed or solid-state electronic position detection.
