About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X20-10
The AirTAC MBLCJ20X20-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. With a 20mm bore, it delivers 157N push and 132N pull force at 0.5 MPa. The rear stopper allows you to trim up to 10mm of travel, creating a usable stroke window of 10 to 20mm for precise end-positioning in tight spaces.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable air cushioning to decelerate loads smoothly at the stroke ends, protecting the end covers from impact. The riveted rolling-packed aluminum barrel and 20um hard-chrome plated carbon-steel rod ensure durability. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. The rear adjuster acts strictly as a travel stop and does not hold 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 (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 MBLCJ20X20-10 Is Used
PCB Component Insertion
The 10-20mm adjustable stroke window provides exact depth control for pressing small electronic connectors onto PCBs without damaging the board surface.
Micro Dispense Valve Actuation
Tunable air cushioning ensures the 8mm rod decelerates smoothly at the end of its 20mm travel, preventing liquid splashing in micro-dosing pump heads.
Small Part Ejection
Delivering 132N pull force at 0.5 MPa, it reliably retracts small plastic clips from an injection mold cavity before the main robot unloads the batch.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X20-10 the Right Cylinder?
At 157N push force at 0.5 MPa, stepping up to the 25mm bore yields 245N for heavier loads, while stepping down is not an option as 20mm is the smallest available size. Choose this MBLCJ over the MBLJ when your application requires tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need the 10-20mm rear travel adjustment window. Remember that the adjuster is a physical stop, not a lock; the cylinder will drift without live air pressure, so external locking mechanisms are required for fail-safe holding. Mounting is limited to Basic, FA flange, or LB foot styles (no SDB or back-cover options). For an exact replacement, match the 20mm bore, 20mm stroke, 10mm adjust code, G1/8 port, PT thread, and note the absence of the -S magnet suffix.
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 MBLCJ20X20-10 FAQ
This 20mm bore cylinder provides 157N push and 132N pull force at 0.5 MPa, 220N push at 0.7 MPa, and a maximum theoretical output of 32 kgf at 1.0 MPa.
No, this specific SKU lacks the -S code, meaning no built-in magnet is fitted. You must select an MBLCJ20X20-10S variant to use CMSG reed or DMSG/EMSG electronic sensors for rod detection.
