Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X450S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X450S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 450mm 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 MBLD40X450S
The AirTAC MBLD40X450S is a double-acting, double-rod aluminum mini cylinder engineered for applications requiring equal bi-directional force. Because a Ø16 mm rod protrudes from both end covers, the effective piston area is identical on extend and retract, yielding 528 N of force each way at 0.5 MPa. The 450 mm stroke provides substantial travel for indexing or transferring parts across machinery stations. The riveted aluminum barrel keeps the body compact while the 20 µm hard-chrome plating on the carbon-steel rod ensures wear resistance.
This SKU includes a built-in magnet (-S) for position detection with AirTAC CMSG (reed), DMSG, or EMSG (solid-state) switches. A defining mechanical trait of the double-rod layout is the ability to mount a workpiece on the front rod and a position flag, cam, or secondary tool on the rear rod, which simultaneously improves anti-rotation stability. Overall length equals the base body length plus twice the stroke, so rear-rod clearance must be designed into the machine. End-of-stroke energy is absorbed by a fixed rubber bumper.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X450S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X450S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 450 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 MBLD40X450S Is Used
Printed Circuit Board Transfer
Moves PCB panels between etching and inspection stations using 528 N of equal force, with the rear rod driving a cam to actuate a downstream sensor.
Textile Loom Guiding
Extends 450 mm to position yarn guides across a wide weaving bed, leveraging the twin-rod design to prevent binding and maintain parallel tracking.
Semiconductor Wafer Pusher
Transfers wafer cassettes into a vacuum chamber, using the rear protruding rod to trip an external mechanical limit switch for safety interlock.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X450S the Right Cylinder?
When sizing this 40 mm bore, stepping down to the 32 mm variant yields 346 N at 0.5 MPa, while stepping up to the 50 mm bore provides 881 N at 0.5 MPa. If your process involves heavy moving masses at high speeds, consider the MBLCD variant, which replaces the fixed rubber bumper with an adjustable air cushion. Mounting is limited to Basic, FA (flange), or LB (foot) brackets; the MBLD has no back-cover or SDB pivot option. Note that the bumper softens impact but does not lock the rod—unpowered position holding requires an external locking device. For a direct replacement, match the 40 mm bore, 450 mm stroke, G1/4 port, PT thread, and -S magnet.
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 MBLD40X450S FAQ
The MBLD40X450S provides equal force in both extend and retract directions due to the double-rod design. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum theoretical force of 108 kgf at 1.0 MPa.
Unlike a single-rod cylinder where push force exceeds pull force, the MBLD has a rod exiting both ends, making the annulus area and force identical both ways. This allows you to mount a workpiece on the front rod and a cam or position flag on the rear rod, while also improving load guidance against rotation.
