About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-30S
The AirTAC MBLCJ25X100-30S 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 30 mm rear trimmer allows you to set a precise usable travel window of 70 to 100 mm, ensuring exact end-positioning for dynamic tasks.
This model includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed switches or DMSG and EMSG solid-state sensors. Unlike the standard MBLJ bumper, the adjustable air cushion uses screw-tunable deceleration to protect the end covers during high-speed operations. The riveted rolling-packed barrel and 20 µm hard-chrome carbon-steel rod provide durable, low-friction operation in tight spaces.

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 MBLCJ25X100-30S Is Used
PCB Depaneling Saw
Feeds a circular saw blade at a controlled rate. The 70-100 mm stroke window sets the exact cut depth, while the air cushion prevents jarring stops that could fracture the board.
Textile Loom Tensioner
Shifts a yarn guide bar across the warp beam. The 245 N push force at 0.5 MPa overcomes friction, and the cushioned ends absorb the rapid reversals of the weaving cycle.
Bottle Capping Head
Lowers a spin-on capping chuck onto plastic containers. The tunable cushion applies the cap smoothly without shattering the plastic, while the magnet confirms the down position.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-30S the Right Cylinder?
Choose this 25 mm bore when you need 245 N of thrust at 0.5 MPa. If your application requires less force, step down to the 20 mm bore which provides 157 N of push force. For heavier payloads, step up to the 32 mm bore, which yields 402 N at 0.5 MPa. The MBLCJ is preferred over the MBLJ when you need tunable end-of-stroke deceleration rather than a fixed rubber bumper, and over the MBLC when you require a rear travel stopper.
Remember that the rear adjuster is a travel stop, not a load-holding lock; the cylinder will drift without live air pressure, and the cushion only decelerates the load. Mounting is limited to Basic, FA (flange), or LB (foot) styles—SDB pivot or back-cover options are not available. For exact replacement, match the 25 mm bore, 100 mm stroke, 30 mm adjust code, G1/8 port, PT thread, and the -S magnet.
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 MBLCJ25X100-30S FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The adjustable stroke uses a 30 mm rear stopper to mechanically set your travel end within a 70-100 mm window. The adjustable air cushion uses a screw valve to tune end-of-stroke deceleration. Neither holds the load; the cylinder drifts without live air.
