About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X75-10S
The AirTAC MBLCJ20X75-10S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers 157 N push and 132 N pull at 0.5 MPa. The 10 mm rear adjuster creates a usable 65-75 mm stroke window, letting you fine-tune the end position without machining spacers.
Unlike the fixed rubber bumper on the base MBLJ, the screw-tunable cushion valves let you dial in end-of-stroke deceleration for faster cycles without slamming the covers. The 8 mm carbon-steel rod has 20 um hard-chrome plating to resist scuffing, while the riveted aluminum barrel keeps weight down in tight spaces. The -S magnet works with CMSG reed and DMSG/EMSG electronic switches for position feedback.

|---|---|---|
| 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 MBLCJ20X75-10S Is Used
PCB Depaneling Router
Extends 65-75 mm to press a circuit board against a routing fixture, using the tunable cushion to soften the 157 N end impact and protect delicate traces.
Micro-Dispense Valve
Triggers a dosing head with a 10 mm stroke trim for exact shot volume, while the DMSG electronic switch confirms the exact extend position.
Label Applicator Wipe
Wipes a label onto small vials; the adjustable rear stopper sets the exact 65-75 mm reach so the pad matches varying container widths.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X75-10S the Right Cylinder?
At 157 N push, this 20 mm bore suits light pick-and-place. If you need less force, no smaller MBL bore exists. To step up, the 25 mm bore gives 245 N push at 0.5 MPa. Choose this MBLCJ over the MBLJ when you need tunable deceleration instead of a fixed bumper, or over the MBLC when you need the 10 mm rear stroke trim. Remember the adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure.
Mounting is limited to Basic, FA flange, or LB foot; there is no SDB pivot or back-cover option. The overall length grows by the 10 mm adjuster plus twice the stroke. To replace this SKU, match the 20 mm bore, 75 mm stroke, 10 mm adjust, G1/8 port, PT thread, and the -S magnet. At 75 mm stroke, the 8 mm rod is short enough to avoid bending, but long strokes need an external guide.
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 MBLCJ20X75-10S FAQ
At 0.5 MPa it gives 157 N push and 132 N pull. At 0.7 MPa it gives 220 N push. The maximum theoretical force is 32 kgf at 1.0 MPa.
The 10 mm rear adjuster is a mechanical travel stop that sets your exact 65-75 mm end position, but it does not lock or hold the load. The adjustable air cushion is a screw valve that tunes end-of-stroke deceleration to protect the covers from impact.
