About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X160-40
The AirTAC MBLCJ20X160-40 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. The rear stopper trims up to 40mm of travel, creating a usable stroke window of 120-160mm. With a 20mm bore, it delivers 157N push and 132N pull force at 0.5 MPa, making it well-suited for precise positioning tasks over mid-range distances.
This model uses a riveted rolling-packed barrel and a 20um hard-chrome plated carbon-steel rod to resist wear. The adjustable air cushion allows you to tune end-of-stroke deceleration for faster cycles while protecting the end covers from impact. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The adjuster acts purely as a travel 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 MBLCJ20X160-40 Is Used
PCB Drill Bit Changer
Indexes tool carousels in PCB routing machines, using the 120-160mm window to compensate for fixture height variations while the air cushion protects the spindle cover.
Label Applicator Tamp
Pushes tamp pads onto packaging in continuous-flow lines, leveraging the 157N push force and tuned cushioning to prevent label skewing at high cycle rates.
Textile Yarn Guide
Positions yarn guides in weaving looms where the 132N pull force retracts the rod smoothly, while the 8mm hard-chrome rod resists lint and friction wear.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X160-40 the Right Cylinder?
At 0.5 MPa, this 20mm bore provides 157N of push force. If your application requires less force, the smaller 12mm bore is not an option in this series, so you are at the minimum size; if you need more power, stepping up to the 25mm bore yields 245N push force. Choose the MBLCJ over the MBLJ when you need screw-tunable deceleration instead of a fixed rubber bumper, or choose the MBLC if you prefer a fixed stroke without the rear adjuster.
Remember that neither the rear travel stopper nor the air cushion acts as a locking mechanism; the rod will drift if air is removed, so use an external guide or lock for position holding. Mounting is limited to Basic, FA flange, or LB foot styles (no SDB pivot or back-cover options). To match this exact replacement, specify: 20mm bore, 160mm stroke, 40mm adjust code, G1/8 port, PT thread, and no magnet. Because the 160mm stroke is relatively long for an 8mm rod, ensure an external guide prevents rod bending under side-loads.
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 MBLCJ20X160-40 FAQ
At 0.5 MPa, this 20mm bore cylinder provides 157N push force and 132N pull force. At 0.7 MPa, the push force increases to 220N. The maximum theoretical force is 32 kgf at 1.0 MPa.
No. This specific SKU does not have a built-in magnet (no -S code), so it cannot support AirTAC CMSG, DMSG, or EMSG position sensors. You would need the MBLCJ20X160-40S variant for electronic position feedback.
