About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X160-50
The AirTAC MBLCJ20X160-50 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 157N of push force and 132N of pull force at 0.5 MPa. The rear adjuster trims up to 50mm of travel, yielding a usable stroke window of 110-160mm, making it highly versatile for varying pick-and-place heights. An M8x1.25 rod-end thread and G1/8 port ensure straightforward pneumatic and mechanical integration.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable air cushions to decelerate the rod smoothly at each end, protecting the end covers during faster cycling. The 8mm carbon-steel rod features 20μm hard-chrome plating to resist wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication over long service life. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without modification.

| 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 MBLCJ20X160-50 Is Used
PCB Depaneling Router
Drives a routing bit carriage across a 110-160mm window; the adjustable air cushion prevents end-cover impact during rapid routing passes.
Micro-Dispense Valve
Trims the exact dispense height on a solder paste printer, using the 50mm rear stopper to dial in the precise 157N contact pressure.
Label Applicator Arm
Actuates a wipe-down blade for bottle labeling; the riveted aluminum barrel keeps the assembly light for high-speed packaging lines.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X160-50 the Right Cylinder?
With a 157N push force at 0.5 MPa, this 20mm bore suits light-duty actuation. If you need less force, step down to the 12mm bore series; if your payload is heavier, step up to the 25mm bore which provides 245N push at 0.5 MPa. Choose this MBLCJ over the MBLJ when your cycle speeds demand adjustable end-deceleration rather than a fixed bumper, or over the MBLC when you need the 50mm rear travel trim to fine-tune the end position. Remember the rear adjuster is a mechanical travel stop, not a load lock; the cushion only decelerates, so use an external locking device if the rod must hold position without live air. Mounting is limited to Basic, FA flange, or LB foot styles (no SDB or back-cover options exist). To match this replacement exactly: 20mm bore, 160mm stroke, 50mm adjust code, G1/8 port, PT thread, no magnet, and Basic mounting.
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 MBLCJ20X160-50 FAQ
At 0.5 MPa, this 20mm bore cylinder provides 157N of push force and 132N of 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 lacks the -S code, meaning no internal magnet is fitted, so it cannot trigger CMSG reed or DMSG/EMSG electronic sensors. You must select an MBLCJ20X160-50S variant to enable position detection.
