About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X25-10
The AirTAC MBLCJ25X25-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. You can trim up to 10mm of travel at the rear, creating a usable stroke window of 15-25mm. Driven by a Ø10mm rod through G1/8 ports, it delivers 245N of push force and 206N of pull force at 0.5 MPa. This specific SKU omits the built-in magnet, meaning it cannot support a CMSG, DMSG, or EMSG position sensor.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable deceleration to absorb kinetic energy at the stroke extremes, protecting the end covers during rapid cycles. The riveted rolling-packed barrel and grease-retaining piston seal maintain consistent lubrication, while the 20um hard-chrome plating on the carbon-steel rod defends against wear. Remember that the rear stopper sets the travel end and the cushion governs speed; neither component mechanically locks or holds the load in place.

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 MBLCJ25X25-10 Is Used
PCB Pick-and-Place
Ideal for compact electronics assembly, using the 15-25mm stroke window to fine-tune the exact lowering distance for a vacuum gripper picking delicate PCBs, relying on the 245N push force to overcome spring-loaded nests.
Label Applicator Tamp
The tunable air cushion allows a smooth, non-destructive contact when tamping labels onto plastic bottles, adjusting the end-of-stroke deceleration to prevent label slippage during high-speed 30-800mm/s cycles.
Small Parts Sorter
Provides a precise 25mm ejection stroke for diverting small plastic fittings on a conveyor, where the adjustable stopper sets the exact push depth into the sorting chute without slamming the end cover.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X25-10 the Right Cylinder?
If you need to step down from this 25mm bore, the 20mm bore offers 157N push at 0.5 MPa, whereas stepping up to the 32mm bore provides 402N. Choose this MBLCJ variant over the MBLJ when your application's moving mass requires tunable end-of-stroke deceleration rather than a fixed bumper shock. To replace this unit exactly, match the 25mm bore, 25mm stroke, 10mm adjust code, G1/8 PT port, and lack of a magnet. Mounting is limited to Basic, FA flange, or LB foot brackets, as no SDB pivot or back-cover options exist for this series. Because the stroke is short, side-load risks are minimal, but an external guide is still recommended for heavy lateral loads.
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 MBLCJ25X25-10 FAQ
At 0.5 MPa, this 25mm bore cylinder provides 245N of push force and 206N of pull force. At 0.7 MPa, the push force increases to 343N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No, this specific MBLCJ25X25-10 SKU does not have a built-in magnet and therefore cannot support AirTAC CMSG, DMSG, or EMSG position switches. You would need the -S variant of this model to use electronic or reed sensors.
