About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X75-10
The AirTAC MBLCJ20X75-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and twin adjustable air cushions. A bore 20mm yields 157N push and 132N pull at 0.5MPa. The 10mm rear adjuster creates a usable 65-75mm travel window, ideal for fine-tuning end positions on small actuators. This PT-threaded unit uses an Ø8 rod and G1/8 port.
Unlike the base MBLJ with its fixed rubber bumper, this model uses screw-tunable air cushions at both ends to decelerate heavier loads smoothly. The riveted rolling-packed barrel and grease-retaining piston seal maintain tight tolerances in confined spaces. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG or DMSG position sensors. The rear stopper sets the travel end; it is a mechanical stop, not a load-holding 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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 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 MBLCJ20X75-10 Is Used
PCB Router Z-Axis
Provides 157N of push force at 0.5MPa for spindle positioning on a PCB depaneling router, using the 65-75mm window to set exact cutting depth without crashing.
Micro-Dispense Head
Tunable air cushions soften the end-of-stroke impact on a liquid dispensing valve actuator, preventing fluid shear degradation during fast 75mm strokes.
Wire Cutters Feed
Drives a small pneumatic wire cutter feed mechanism where the 132N pull force reliably retracts the 8mm rod against light spring tension in tight assembly cells.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X75-10 the Right Cylinder?
For higher force needs, stepping up to the 25mm bore yields 245N push at 0.5MPa; if lower force is acceptable, there is no smaller standard MBL size below 20mm. Choose this MBLCJ over the MBLJ when your 75mm move requires tunable deceleration rather than a fixed bumper impact. Remember that neither the air cushion nor the stroke adjuster acts as a brake; use an external locking mechanism if the load must hold position without live air. Mounting is limited to Basic, FA, or LB styles (no SDB or back-cover options). To match this replacement exactly: 20mm bore, 75mm stroke, 10mm adjust code, PT thread, G1/8 port, and no magnet (non-S).
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 MBLCJ20X75-10 FAQ
At 0.5MPa, this 20mm bore cylinder provides 157N push and 132N pull force. At 0.7MPa, the push increases to 220N. The maximum theoretical force is 32kgf at 1.0MPa.
The rear stroke adjuster trims the travel end-point within a 65-75mm window, acting as a mechanical stop. The adjustable air cushion screw tunes end-of-stroke deceleration speed. Neither holds a load in place without air pressure.
