About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X20-20
The AirTAC MBLCJ32X20-20 is a compact double-acting mini cylinder featuring a 32mm bore and a 20mm stroke. It integrates a rear travel stopper allowing you to trim up to 20mm at the rear, creating a usable end-position window of 0-20mm. Delivering 402N of push force at 0.5MPa, it is paired with an adjustable air cushion at both ends to screw-tune end-of-stroke deceleration for quick, heavy moves.
This configuration uses a G1/8 port and a Ø12mm hard-chrome plated rod with an M10x1.25 end thread. Because this SKU lacks the -S suffix, it has no internal magnet and cannot support CMSG, DMSG, or EMSG position sensing. The riveted aluminum barrel keeps weight low, while the rear stopper sets the travel limit without mechanically locking the load in place.

| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 MBLCJ32X20-20 Is Used
PCB Edge Router Damping
Provides 402N of thrust to clamp printed circuit boards during routing, using the 0-20mm adjustable window to dial in exact clamping depth while the air cushion absorbs the tool vibration.
Micro-Pneumatic Press
Ideal for small stamping or pin-insertion tasks needing 346N pull force, where the dual end cushions prevent shock damage to the machine frame at the end of the 20mm travel.
Thin-Film Web Tensioning
Acts as a compact tensioning nip in packaging machines, using the 0-20mm stroke adjustment to accommodate varying material thicknesses without requiring a sensor.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X20-20 the Right Cylinder?
For lower force needs, stepping down to the 25mm bore yields 245N push at 0.5MPa, whereas stepping up to the 40mm bore provides 628N. Choose this MBLCJ over the MBLJ if your application requires tunable end-cover protection via air cushions rather than a fixed rubber bumper, or over the MBLC if you need to fine-tune the rear stroke length. The overall length equals A + 2 x stroke + adjust, so plan your envelope accordingly.
When replacing this unit, match the 32mm bore, 20mm stroke, 20mm adjust code, G1/8 PT thread, and Basic mounting (no FA/LB specified). Remember that the adjuster is a travel stop, not a lock; the cylinder will drift without live air pressure. Mounting is limited to Basic, FA, or LB, as no back-cover or SDB pivot options exist for this series.
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 MBLCJ32X20-20 FAQ
At 0.5MPa, this 32mm bore cylinder provides 402N of push force and 346N of pull force. At 0.7MPa, the push force increases to 563N. The maximum theoretical force is 82kgf at 1.0MPa.
No, because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot be used with AirTAC CMSG, DMSG, or EMSG switches. Additionally, the 0-20mm adjustable stroke is set by a rear travel stop, which only defines the end position and does not lock the load.
