About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X30-10
The AirTAC MBLCJ25X30-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The 10 mm rear adjuster yields a usable travel window of 20 to 30 mm, ideal for short-travel positioning. Because this SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor.
Unlike the fixed rubber bumper on an MBLJ, the adjustable air cushion lets you screw-tune end-of-stroke deceleration for faster, heavier moves without slamming the covers. The riveted rolling-packed barrel and grease-retaining piston seal keep it compact, while the Ø10 carbon-steel rod with 20 µm hard-chrome plating resists wear. Remember the rear stopper sets the travel end but does not lock the load; external guides are recommended for side-load stability.

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 MBLCJ25X30-10 Is Used
PCB Router Z-Axis Stop
Tunes the 20-30 mm travel window to set precise router depth, while the air cushion prevents snap-back impact on high-speed retraction.
Microfluidic Valve Actuation
Uses the 245 N push force to open manifold valves, with the adjustable end-position trim ensuring the valve stem is not over-traveled.
Small-Part Ejector
Ejects stamped electronics parts at speed, relying on the tunable cushion to decelerate the 30 mm stroke quietly without machine shake.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X30-10 the Right Cylinder?
If you need less force, step down to the 20 mm bore (157 N push @0.5 MPa); if your payload requires more, step up to the 32 mm bore (402 N push @0.5 MPa). Choose this MBLCJ over the MBLJ when you need tunable end-deceleration instead of a fixed bumper, or over the MBLC when you need to trim the end position by 10 mm. The rear adjuster acts as a travel stop, not a lock; the rod will drift without live air pressure. Mounting is limited to Basic, FA flange, or LB foot (no SDB or back-cover options). For a direct replacement, match bore 25, stroke 30, adjust 10, G1/8 port, 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 MBLCJ25X30-10 FAQ
At 0.5 MPa, the 25 mm bore 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. Operating pressure ranges from 0.15 to 1.0 MPa.
This specific SKU lacks the -S code, so no magnet is fitted and it cannot accept CMSG, DMSG, or EMSG sensors. The 10 mm rear adjuster trims the usable stroke to 20-30 mm but acts only as a travel stop; it does not lock or hold the load without continuous air pressure.
