About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X60-10
The AirTAC MBLCJ20X60-10 is a compact double-acting aluminum mini cylinder featuring a rear travel stopper that trims up to 10 mm, yielding a usable extension window of 50 to 60 mm. A screw-tunable adjustable air cushion at both ends manages end-of-stroke deceleration, protecting the end covers during faster cycling. Delivering 157 N of push force at 0.5 MPa, this 20 mm bore unit is tailored for lighter-duty positioning tasks.
This SKU uses an Ø8 mm hard-chrome plated carbon-steel rod with an M8x1.25 end thread, a G1/8 port, and default PT tapered piping. It lacks the -S magnet option, meaning it cannot accept a CMSG or DMSG position sensor. The riveted rolling-packed barrel and grease-retaining piston seal ensure stable friction, while the rear adjuster acts purely as a mechanical stop and does not lock 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 MBLCJ20X60-10 Is Used
PCB Component Placement
Provides 157 N of precise push force for pressing small electronic connectors onto printed circuit boards, using the 50-60 mm stroke window to dial in exact insertion depth without overdriving.
Micro Dispenser Dosing
Tunes the air cushion to gently stop the 60 mm travel when actuating a micro-dosing valve for adhesives, preventing fluid shear and splashing at the stroke end.
Thin-Wall Tube End Forming
Uses the 132 N pull force to retract a small mandrel used in thin-wall brass tube flaring, relying on the adjustable stopper to set the exact 55 mm retraction point.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X60-10 the Right Cylinder?
Stepping down to the 20 mm bore is ideal when the smaller 16 mm class lacks thrust; conversely, the next size up, the 25 mm bore, offers 245 N push at 0.5 MPa for heavier resistance. Choose this MBLCJ over the MBLJ if your application needs tunable deceleration rather than a fixed rubber bumper, or over the MBLC if you require on-machine stroke length tuning. Remember that neither the rear stopper nor the air cushion serves as a load-holding brake—external locking mechanisms are required for position holding. Mounting is limited to Basic, FA flange, or LB foot styles, as rear back-cover or SDB pivot configurations are unavailable. To match this exact replacement, specify a 20 mm bore, 60 mm stroke, 10 mm adjuster, G1/8 port, PT thread, and no 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 MBLCJ20X60-10 FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N push and 132 N pull force. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa operating pressure.
No, this specific SKU lacks the -S built-in magnet, so it cannot accommodate AirTAC CMSG (reed) or DMSG/EMSG (electronic) position switches. You would need to select an MBLCJ model with the -S suffix for sensor compatibility.
