Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X250S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X250S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 250mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 881 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X250S
The AirTAC MBLD50X250S is a double-acting, double-rod aluminum mini cylinder featuring a 50mm bore and 250mm stroke. Because a Ø16mm carbon-steel rod protrudes from both end covers, the effective piston area is identical on extend and retract. This yields exactly 881 N of force in both directions at 0.5 MPa, eliminating speed and force mismatches. The built-in magnet (-S) enables contactless position detection via CMSG reed or DMSG/EMSG electronic switches.
This 250mm stroke suits mid-range indexing and dual-tooling tasks. A rod extending from the rear cover allows you to mount a position flag or drive a secondary mechanism simultaneously. The riveted rolling-packed barrel and grease-retaining seal keep it compact, while the fixed rubber bumper absorbs end-of-stroke impact. Overall length equals A plus 2 x stroke, so you must leave physical clearance for the rear rod.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X250S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X250S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 250 mm |
| Acting type | Double acting, double rod |
| Port size | G1/4 |
| Rod thread | M14×1.5 |
| 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 (Ø50mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 MBLD50X250S Is Used
PCB Edge Conveyor Routing
Drives a dual-sided routing head on an electronics assembly line, using the 881 N equal force to cleanly cut and retract through fiberglass panels without speed variance.
Textile Loom Beam Indexer
Shifts heavy warp beams laterally using both rod ends: one side pushes the beam while the rear rod extends to trigger a cam-operated tensioner switch.
Injection Mold Core Puller
Extracts a symmetrical mold core in a plastics molding machine, relying on the 250mm stroke and equal push/pull dynamics to prevent binding during long draws.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X250S the Right Cylinder?
Step down to the 40mm bore if your application only requires 528 N at 0.5 MPa, or step up to the 63mm bore for 1457 N at 0.5 MPa if this 50mm unit stalls under load. Choose the MBLCD variant if your cycle speed demands adjustable air cushions rather than the fixed rubber bumper found here. Mounting is limited to Basic, FA flange, or LB foot brackets—MBLD lacks back-cover or SDB pivot options. A plain bumper does not hold position without live air; use an external locking device if mid-stroke holding is required.
When ordering a replacement, match the 50mm bore, 250mm stroke, G1/4 port, PT thread, and -S magnet. At 250mm stroke, the twin 16mm rods still need an external guide to prevent bending under heavy lateral loads.
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 MBLD50X250S FAQ
Because the double-rod design has equal annulus area on both sides, push and pull forces are identical: 881 N at 0.5 MPa, 1233 N at 0.7 MPa, and a maximum theoretical 180 kgf at 1.0 MPa.
A rod exits both ends, making extend and retract forces perfectly equal. The rear rod can mount a position flag or secondary tool, but it requires rear clearance. The -S code means a magnet is fitted for CMSG/DMSG/EMSG sensors.
