About the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ20X225-10S
The AirTAC MBLJ20X225-10S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster. It delivers 157 N of push force at 0.5 MPa via an 8 mm carbon-steel rod. The integrated -10 mm stopper screw provides a usable end-position window of 215-225 mm, allowing precise tuning without external stops.
Equipped with a built-in magnet (-S), this unit supports CMSG reed and DMSG/EMSG electronic sensors for position feedback. It uses a fixed rubber bumper to soften end impacts. The riveted rolling-packed barrel and grease-retaining piston seal ensure reliable operation within its 30-800 mm/s speed range.

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 MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ20X225-10S Is Used
PCB Edge Guide Tuning
Micro-adjusts the 215-225 mm end stop during conveyor width changeovers in electronics assembly lines.
Sensor Probe Positioning
Uses the DMSG electronic switch to confirm the 157 N extension for testing microchips.
Thin Film Cutting
Sets a precise 215 mm cutting depth on packaging machines without adding bulky external stops.
Is the Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ20X225-10S the Right Cylinder?
Step down to the 20 mm bore if you need less force, or step up to the 25 mm bore for 245 N push at 0.5 MPa. Choose this MBLJ over a fixed-stroke MBL when you need 10 mm of rear trim for product changeovers. For heavier kinetic energy, the MBLCJ variant adds adjustable air cushions.
The rear adjuster is a travel stop, not a lock; it will not hold the load without live air. Mounting is limited to Basic, FA, or LB (no SDB or back cover). Exact replacement requires 20 mm bore, 225 mm stroke, 10 mm adjust, G1/8 port, PT thread, and the -S magnet. At 225 mm stroke, the 8 mm rod is prone to bending under lateral loads—always use 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 MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ20X225-10S FAQ
At 0.5 MPa it provides 157 N push and 132 N pull. At 0.7 MPa it provides 220 N push. The maximum theoretical force is 32 kgf at 1.0 MPa.
The rear stopper screw trims the stroke end position, creating a usable window from 215 mm to 225 mm. It acts only as a travel stop and does not lock the load without live air.
