Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X15
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X15 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 15mm 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 MBLD40X15
The AirTAC MBLD40X15 is a double-acting, double-rod aluminum mini cylinder featuring a 40 mm bore and a 15 mm stroke. Because a Ø16 mm carbon-steel rod protrudes from both end covers, the effective piston area is identical on extend and retract. This yields exactly 528 N of force at 0.5 MPa in both directions, making it ideal for short, symmetrical motions where push and pull dynamics must match.
The ultra-short 15 mm stroke is built for tight spaces where only a small pinch or release is needed. The riveted rolling-packed aluminum barrel houses a fixed rubber bumper at each end to soften impact, and the heterogeneous two-way grease-retaining piston seal maintains lubrication. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X15 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X15 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 15 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 MBLD40X15 Is Used
Stamping Press Ejection
Provides 528 N of equal push/pull force at 0.5 MPa to eject small stamped metal brackets from a die, using the rear rod to simultaneously trip a mechanical limit flag.
PCB Edge Guiding
Uses the 15 mm stroke to center and release electronic printed circuit boards on a conveyor, relying on twin rods to prevent binding during rapid 30-800 mm/s cycles.
Film Web Tracking
Pivots a low-friction guide roller on a packaging line; the double-rod design ensures the 528 N guiding pressure remains constant whether the web shifts left or right.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X15 the Right Cylinder?
Stepping down to the 32 mm bore drops the both-way force to 346 N at 0.5 MPa, whereas stepping up to the 50 mm bore raises it to 881 N. Choose this 40 mm option when you need moderate force in a very compact footprint. Mounting is limited to Basic, FA flange, or LB foot brackets—there is no back-cover or SDB pivot option for the double-rod design. If your application requires adjustable air cushioning rather than fixed rubber bumpers, select the MBLCD variant. For exact replacements, match the 40 mm bore, 15 mm stroke, G1/4 port, PT thread, and no-magnet configuration.
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 MBLD40X15 FAQ
Because the MBLD40X15 is a double-rod cylinder, the annulus area is equal on both sides, meaning push and pull forces are identical. It generates 528 N at 0.5 MPa and 739 N at 0.7 MPa in both directions. The maximum theoretical force is 108 kgf at 1.0 MPa.
A double-rod cylinder has a rod exiting both end covers, yielding equal force and speed in both directions. The rear rod can drive a secondary mechanism or position flag. Note that this MBLD40X15 SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG sensors for position detection.
