Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X100S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X100S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 100mm 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.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X100S
The AirTAC MBLD40X100S is a compact double-acting double-rod aluminum mini cylinder engineered for symmetrical motion. Because a Ø16 mm carbon-steel rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 528 N of force each way at 0.5 MPa. A 100 mm stroke on this 40 mm bore is ideal for mid-travel transfer tasks where maintaining equal push and pull velocity prevents machine timing jams.
The riveted rolling-packed aluminum barrel houses a grease-retaining two-way piston seal, while a fixed rubber bumper absorbs end-of-stroke impact. The built-in magnet (-S) allows a CMSG reed or DMSG/EMSG electronic switch to track position. Overall length equals A + 2 x stroke, meaning the rear rod protrudes equally and requires clear space to mount a cam or position flag. Mounting is restricted to Basic, FA flange, or LB foot; no back-cover or SDB pivot exists.

| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X100S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 100 mm |
| Acting type | Double acting, double rod |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
Double-rod overall length = A + 2 × stroke — leave clearance for the rear rod. MBLD/MBLCD mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Output Force (Ø40mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 528 N |
| 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.

Where the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X100S Is Used
PCB Depaneling Saw Feed
Drives a circular saw carriage on a 100 mm stroke, utilizing the equal 528 N extend and retract force to maintain constant blade feed speed and avoid binding during board separation.
Textile Loom Tensioner
Uses the twin-rod anti-rotation property to keep a thread guide bar perfectly aligned without twisting, while the rear rod end mounts a mechanical limit flag to verify yarn travel.
Connector Pin Insertion
Presses delicate pins into molded plastic connectors; the 40 mm bore provides stable 528 N clamping at 0.5 MPa, and the -S magnet triggers a DMSG solid-state sensor to confirm pin seating.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X100S the Right Cylinder?
Choose this 40 mm bore when an application demands 528 N of symmetrical force at 0.5 MPa. If you need less output, stepping down to the 32 mm bore drops the equal both-way force to 346 N. Stepping up to the 50 mm bore raises it to 881 N. The G1/4 port matches the 50/63 mm sizes, ensuring adequate flow for the 30-800 mm/s speed range.
Unlike the single-rod MBL which has unequal push/pull areas, this MBLD provides identical bidirectional dynamics. If end impact is too harsh, the MBLCD variant offers adjustable air cushions, whereas this base MBLD relies solely on a fixed rubber bumper. For exact replacement matching, verify the 40 mm bore, 100 mm stroke, G1/4 port, PT thread, and the -S magnet. Note that a plain MBLD drifts without live air—the bumper softens impact but does not lock position.
Quick checklist
- ✓ Equal force both ways at your pressure
- ✓ Rear-rod clearance (length = A + 2 × stroke)
- ✓ Mounting: Basic / FA / LB only
- ✓ 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 Leave clearance for the rear rod (length = A + 2 × stroke).
- 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 MBLD Dual Axis Type Mini Cylinder MBLD40X100S FAQ
Because the double-rod design has equal piston areas on both sides, push and pull forces are identical: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum theoretical 108 kgf at 1.0 MPa.
A single-rod cylinder has a larger push area than pull area, causing unequal speed and force. The MBLD double-rod makes them equal, and the protruding rear rod allows you to mount a second tool, cam, or position flag while improving load guidance against rotation.
