About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X225-20
The AirTAC MBLCJ32X225-20 is a compact, double-acting mini cylinder featuring a rear travel stopper that permits a 20 mm trim, yielding a usable extension window of 205 to 225 mm. It integrates a screw-tunable air cushion at both ends to decelerate the rod smoothly, protecting the end covers during high-speed operations. Driven by a Ø12 mm carbon-steel rod, it delivers 402 N of push force and 346 N of pull force at 0.5 MPa.
This specific configuration omits the built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without a physical switch replacement. The riveted rolling-packed aluminum barrel and heterogeneous grease-retaining piston seal ensure stable friction characteristics, while the 20 µm hard-chrome plating on the rod resists scuffing. Remember, the rear stopper sets the travel end and the cushion only decelerates; neither component mechanically locks or holds the load in place without continuous air pressure.

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 MBLCJ32X225-20 Is Used
PCB Router Z-Axis
Drives a spindle carriage up and down; the 205-225 mm window allows precise depth calibration for cutting various board thicknesses, while the air cushion prevents carriage bounce at stroke end.
Bottle Capper Head
Applies 402 N of downward clamping force to secure aluminum caps onto glass bottles, using the adjustable stroke to accommodate different container neck heights without changing the entire fixture.
Textile Fabric Guide
Extends to position a fabric edge-guide roller on automated looms, relying on the tunable cushion to softly decelerate the 225 mm move and avoid snapping delicate yarns.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X225-20 the Right Cylinder?
Delivering 402 N push at 0.5 MPa, this 32 mm bore suits medium-duty tasks; if you need less force, step down to the 25 mm bore (245 N push), or move up to the 40 mm bore (628 N push) for heavier loads. Choose this MBLCJ over the MBLJ when your application speed demands tunable end-deceleration rather than a fixed rubber bumper, or over the MBLC if you need to fine-tune the rear travel end within the 205-225 mm window. The rear adjuster acts purely as a mechanical travel stop, and the pneumatic cushion only bleeds off velocity—neither will hold a load statically without live air, so external locking mechanisms are required for fail-safe positioning. Mounting is restricted to Basic, FA flange, or LB foot styles (no SDB pivot or back-cover options are available). For a direct replacement, match the 32 mm bore, 225 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and confirm no magnet is fitted. Given the 225 mm stroke on a Ø12 mm rod, external guide rails are highly recommended to prevent 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 MBLCJ32X225-20 FAQ
At 0.5 MPa, the 32 mm bore provides 402 N push and 346 N pull force; at 0.7 MPa, push increases to 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The rear adjuster is a travel stop and the air cushion only decelerates motion; neither component locks the load, so the rod will drift without live air pressure.
No, this specific SKU lacks the -S code, meaning no internal magnet is fitted. It cannot trigger AirTAC CMSG (reed), DMSG, or EMSG (solid-state electronic) switches. You must select an -S variant or use an external physical sensor for position detection.
