About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X225-100S
The AirTAC MBLCJ40X225-100S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 628 N push and 528 N pull force at 0.5 MPa. The 100 mm rear stopper yields a usable travel window of 125 to 225 mm, ideal for varying insertion depths on packaging equipment. A built-in magnet enables position detection.
This SKU uses a Ø16 mm hard-chrome plated carbon steel rod with an M12x1.25 end thread. The riveted aluminum barrel retains grease via a two-way piston seal. Unlike the MBLJ bumper variant, the screw-tunable cushions decelerate heavy 225 mm moves to protect the end covers. The rear stopper sets the travel end but does not lock the load; external guides are recommended for this length to prevent rod bending.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X225-100S Is Used
Corrugator Stack Pusher
Drives cardboard layers on a corrugating line using 628 N push force, relying on the 125-225 mm adjustable window to match varying pallet heights.
Beverage Line Divertor
Routes heavy bottle crates with the 100 mm rear stroke trim, while the dual air cushions absorb the kinetic energy of rapid 225 mm shifts.
Textile Loom Takedown
Actuates fabric rolls using the M12x1.25 rod thread, using the -S magnet with DMSG electronic switches to trigger precise loop formation.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X225-100S the Right Cylinder?
For lower force needs, step down to the 32 mm bore (402 N push @0.5 MPa). If you need more power, step up to the 50 mm bore (981 N push @0.5 MPa). Choose this MBLCJ over the MBLJ when your 225 mm stroke requires adjustable end-deceleration rather than a fixed rubber bumper. If your travel never changes, the fixed-stroke MBLC saves cost.
The rear 100 mm adjuster sets the end position, while the needle valves tune cushioning—neither holds the load without live air, so use an external lock for static holding. Mounting is limited to Basic, FA, or LB (no SDB or back-cover). The exact replacement match is: 40 mm bore, 225 mm stroke, 100 mm adjust, G1/4 port, PT thread, no mounting code, with an -S magnet.
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 MBLCJ40X225-100S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The 100 mm rear adjuster is a mechanical travel stop that sets your usable window between 125 and 225 mm. The adjustable air cushion uses needle valves to tune end-of-stroke deceleration. Neither acts as a lock to hold a load in place.
