The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X225S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 225mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 528 N each way at 0.5 MPa. Fixed rubber bumper.
The AirTAC MBLD40X225S is a double-acting, double-rod aluminum mini cylinder featuring a 40mm bore and 225mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, delivering an equal 528N force both ways at 0.5MPa. A built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensor switches to track piston position. The 225mm stroke suits mid-range indexing and transfer tasks.
This model uses a Ø16 carbon-steel rod with 20um hard-chrome plating and a G1/4 port. It features a riveted rolling-packed barrel and a fixed rubber bumper. Overall length equals A + 2 x stroke, so rear-rod clearance is mandatory. The twin rods provide dual-side guidance to resist twisting, though long strokes still require an external guide to prevent rod bending under heavy side loads.

| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 kgf |
A rod on both piston faces makes the annulus area equal, so extend and retract force (and speed) are the same. Actual usable force is lower due to friction.

Drives a 225mm transfer arm in a PCB assembly line, using the 528N equal both-way force to push boards onto testing nests without rotational drift.
Mounts a wiper blade on the front rod and a position flag on the rear rod to trigger a DMSG sensor, ensuring flat label application on packaging machines.
Indexes semiconductor wafer cassettes mid-process; the twin-rod anti-rotation property keeps the 225mm stroke perfectly aligned under a 739N load at 0.7MPa.
Step down to the MBLD32 bore for 346N at 0.5MPa if your load is lighter, or step up to the MBLD50 bore for 881N if you need to move heavier fixtures. The fixed rubber bumper softens end-of-travel impact, but for adjustable air cushioning, switch to the MBLCD variant. For single-direction tasks where rear-rod output is unnecessary, the standard MBL single-rod cylinder saves space.
Mounting is limited to Basic, FA flange, or LB foot brackets; MBLD has no SDB pivot or back-cover option. This SKU uses default PT tapered ports and includes the -S magnet for solid-state DMSG/EMSG or reed CMSG sensors. A plain MBLD does not hold position without live air—the bumper is not a lock. For exact replacement, match the 40mm bore, 225mm stroke, G1/4 port, PT thread, and -S magnet.
Quick checklist
Because the rod exits both ends, the force is identical in both directions: 528N at 0.5MPa, 739N at 0.7MPa, and a maximum theoretical 108kgf at 1.0MPa.
A twin-rod cylinder provides equal extend and retract forces and allows a cam or position flag to be mounted on the rear rod. This MBLD40X225S includes a built-in magnet (-S) for CMSG/DMSG/EMSG sensors, but it uses a fixed rubber bumper, not an adjustable cushion.
