About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-75S
The AirTAC MBLCJ25X100-75S is a compact double-acting mini cylinder featuring a rear travel adjuster and tunable air cushions at both ends. The 75 mm adjustment code lets you trim the rear stroke, creating a usable extension window of 25-100 mm. Delivering 245 N push and 206 N pull at 0.5 MPa, it suits mid-range positioning tasks. The adjustable air cushion allows you to screw-tune the end-of-stroke deceleration, absorbing kinetic energy to protect the end covers during faster moves.
This SKU includes a built-in magnet (-S) for pairing with AirTAC CMSG reed or DMSG/EMSG electronic solid-state sensor switches to track rod position. It uses a G1/8 port and an M10x1.25 rod-end thread. The riveted rolling-packed aluminum barrel and 20 um hard-chrome plated carbon-steel rod provide durable, low-friction operation. Remember the rear stopper sets the travel end but does not hold the load, and the cushion only decelerates; neither acts as a mechanical lock.

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 MBLCJ25X100-75S Is Used
PCB Router Z-Axis
Uses the 25-100 mm stroke window to set precise router depth, relying on the 245 N force to plunge the spindle while the air cushion prevents bounce at stroke end.
Dispensing Valve Actuation
Tunable end-deceleration allows the rod to retract smoothly without dripping adhesive, while the -S magnet triggers a DMSG sensor to confirm valve closure.
Small Parts Ejector
Ejects machined aluminum chips from a fixture; the 75 mm rear adjuster dials the exact ejection distance to clear the workzone without hitting the enclosure.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ25X100-75S the Right Cylinder?
Choose this 25 mm bore when you need 245 N of push force at 0.5 MPa with a highly flexible stroke. If your application requires less force, stepping down to the 20 mm bore yields 157 N push. If you need more power, stepping up to the 32 mm bore provides 402 N push. This model is preferred over the MBLJ when a fixed rubber bumper cannot absorb the impact of heavier loads at speed, and over the MBLC when you need to fine-tune the exact end position rather than using a fixed stroke.
For replacement, match the 25 mm bore, 100 mm base stroke, 75 mm adjust code, G1/8 port, PT thread, and the -S magnet. Mounting is limited to Basic, FA flange, or LB foot; there is no back-cover or SDB pivot option. Because the overall length equals A + 2 x stroke + adjust, verify your spatial envelope. The 10 mm rod handles normal loads, but an external guide is recommended to prevent side-loading bending.
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 MBLCJ25X100-75S FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa with a speed range of 30-800 mm/s.
The 75 mm adjustable stroke is a rear mechanical stopper that trims the usable travel window down to 25-100 mm, setting the final end position. The adjustable air cushion is a separate needle valve that tunes the rate of pneumatic deceleration near the stroke ends to absorb shock. Neither feature locks or holds the load in place.
