About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X15-10S
The AirTAC MBLCJ25X15-10S is a compact double-acting aluminum mini cylinder featuring a built-in magnet (-S) and a rear stroke adjuster. It combines a 10mm rear travel stopper with an adjustable air cushion at both ends, giving you a usable stroke window of 5-15mm. Delivering 245N of push force at 0.5 MPa, it suits very short, high-cycle positioning tasks.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this MBLCJ variant uses screw-tunable end-of-stroke cushioning to decelerate heavier or faster moves, protecting the end covers. The riveted rolling-packed barrel and grease-retaining two-way piston seal ensure longevity, while the 20um hard-chrome plated carbon-steel rod resists wear. The rear stopper sets the travel end; it does not hold the load.

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 MBLCJ25X15-10S Is Used
PCB Component Insertion
Provides 245N of precise push force for pressing small connectors onto PCBs, using the 5-15mm stroke window to dial in exact insertion depth without bottoming out.
Micro-Clamp Damping
Tune the adjustable air cushion to softly decelerate a 15mm clamping motion on thin sheet metal, preventing workpiece denting and extending cover life.
Dispenser Valve Toggling
Leverages the -S magnet with a DMSG electronic sensor to trigger a high-speed adhesive dispenser valve exactly at the 5-15mm adjusted stroke endpoint.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X15-10S the Right Cylinder?
Stepping down to the 20mm bore yields 157N push at 0.5 MPa, whereas stepping up to the 32mm bore provides 402N. Choose this 25mm bore when your mechanism requires exactly 245N of push force within a tight 15mm envelope. Compared to the fixed-stroke MBLC, this model allows you to trim the travel down to a 5mm minimum. Remember that the adjuster is a travel stop, not a lock; the cylinder cannot hold position without live air. Mounting is limited to Basic, FA, or LB (no SDB or back-cover options), and the overall length equals A + 2x15 + 10. This SKU uses a PT port and includes the -S magnet for CMSG reed or DMSG/EMSG electronic sensors.
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 MBLCJ25X15-10S FAQ
At 0.5 MPa, this 25mm bore cylinder provides 245N push and 206N pull force. At 0.7 MPa, the push increases to 343N. The maximum theoretical force is 50 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
The adjustable stroke is a rear mechanical stopper that trims your usable travel window down to 5-15mm. The adjustable air cushion is a separate screw-tunable valve that regulates end-of-stroke deceleration. Neither holds the load; an external lock is needed for position holding.
