About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X10-10S
The AirTAC MBLCJ25X10-10S is a compact double-acting mini cylinder featuring a 25mm bore and a 10mm stroke. It delivers 245N push and 206N pull force at 0.5 MPa. The rear adjuster allows you to trim up to 10mm of travel, providing a usable end-position window from 0 to 10mm for exact micro-positioning. Unlike the base MBLJ with its fixed rubber bumper, this MBLCJ variant features a screw-tunable adjustable air cushion at both ends to optimize end-of-stroke deceleration.
This model includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed switches or DMSG and EMSG solid-state sensors. The 10mm piston rod is hard-chrome plated (20um) to resist wear, while the riveted aluminum barrel keeps the body light for tight spaces. Note that the rear adjuster acts purely as a travel stop and does not lock the load in place; external guides are recommended if side loads are present.

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 MBLCJ25X10-10S Is Used
PCB Reject Gates
Uses the 0-10mm adjustable window to precisely time the pop-out of defective printed circuit boards on an SMT line without overshooting into the conveyor belt.
Micro-clamp Release
Leverages the tunable air cushion to softly decelerate the 245N push force, preventing damage to delicate plastic housings during unclamping.
Sensor Positioning
Pairs the built-in magnet with an EMSG solid-state switch to confirm rod extension in compact pneumatic indexing drums where physical space is highly restricted.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X10-10S the Right Cylinder?
With 245N of push force at 0.5 MPa, this 25mm bore is a middle-ground option. If your task requires less force, step down to the 20mm bore (157N push), or step up to the 32mm bore (402N push) for heavier loads. Choose the MBLCJ over the MBLJ when your application's speed or mass requires tunable pneumatic cushioning to prevent end-cover impact. Choose the MBLC if you need a fixed standard stroke without the rear adjustment mechanism.
When ordering a replacement, verify the 25mm bore, 10mm stroke, 10mm adjust code, G1/8 port (PT thread), and the -S magnet. Mounting is limited to Basic, FA (flange), or LB (foot) brackets; this series does not support SDB pivots or back-cover options. Remember that neither the stroke adjuster nor the air cushion will mechanically hold a load without continuous air pressure.
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 MBLCJ25X10-10S 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 theoretical maximum force is 50 kgf at 1.0 MPa.
The 10mm adjustable stroke is a rear mechanical stopper that lets you trim the end position within a 0-10mm window. The adjustable air cushion is a separate screw-tunable valve that controls exhaust flow to decelerate the piston near the stroke ends. Neither feature locks or holds the load mechanically.
