About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-30
The AirTAC MBLCJ25X200-30 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 push and 206 N pull force at 0.5 MPa. The rear stopper lets you trim up to 30 mm of travel, creating a usable 170-200 mm stroke window for precise end-position tuning. A G1/8 port and Ø10 hard-chrome rod handle the 200 mm movement.
This SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG position sensors. The adjustable air cushion uses screw-tunable deceleration to absorb kinetic energy at stroke ends, preventing end-cover damage during fast 200 mm moves. Unlike the base MBLJ with its fixed rubber bumper, this twin-cushion system protects the riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal from impact shock.

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 MBLCJ25X200-30 Is Used
PCB Router Z-Axis
Drives a 200 mm vertical plunge on a printed circuit board routing spindle, using the 170-200 mm adjustable window to set exact cutting depth without moving mechanical hard stops.
Textile Takedown Roll
Actuates a fabric takedown mechanism; the twin adjustable air cushions absorb the 245 N push kinetic energy at the 200 mm stroke end, preventing sudden jerks that would tear synthetic fibers.
Filament Winding Pin
Positions a deflection pin in a composite filament winding machine, where the 30 mm rear adjustment fine-tunes the fiber lay angle without reprogramming the CNC carriage.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X200-30 the Right Cylinder?
Stepping down from this 25 mm bore (245 N push @0.5 MPa), the 20 mm bore offers 157 N push for lighter loads, while stepping up to the 32 mm bore yields 402 N for heavier work. Choose the MBLCJ over the MBLJ when your moving mass requires tunable end-deceleration rather than a fixed bumper, or over the MBLC if you need on-the-fly stroke trimming. The rear adjuster is a mechanical travel stop, not a lock; it will not hold a load pneumatically. For position holding, use an external locking device. Mounting is limited to Basic, FA flange, or LB foot brackets (no SDB pivot or back-cover options). To replace this unit, match the 25 mm bore, 200 mm stroke, 30 mm adjust code, PT thread, and no-magnet configuration.
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 MBLCJ25X200-30 FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, push force is 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, DMSG, or EMSG position sensors. Additionally, the rear stroke adjuster is a travel stop, not a lock, and the air cushion only decelerates; neither holds a load pneumatically. You need live air or an external lock for position holding.
