Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X125S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X125S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 125mm 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 MBLD50X125S
The AirTAC MBLD50X125S is a double-acting, double-rod aluminum mini cylinder engineered for symmetrical motion control. Because a carbon-steel rod protrudes from both end covers, the annulus piston area is identical on extend and retract. This yields exactly 881 N of force at 0.5 MPa in both directions, making the 125 mm stroke ideal for synchronized transfer arms or opposing clamp mechanisms that require balanced momentum. The riveted rolling-packed barrel and 20 um hard-chrome plating withstand harsh shop environments.
The built-in -S magnet enables position detection via CMSG reed or DMSG/EMSG electronic switches mounted along the groove. A defining mechanical advantage of this twin-rod layout is dual-side guidance: mounting a workpiece on the front rod and a cam or position flag on the rear rod actively resists torsional rotation better than a single-rod unit. Impact at end-of-stroke is absorbed by a fixed rubber bumper, while overall length equals A + 2 x stroke, meaning you must leave rear-rod clearance in your machine envelope.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X125S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X125S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 125 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 MBLD50X125S Is Used
PCB Edge-Guide Transfer
Drives a 125 mm stroke transfer arm in a PCB routing machine, using the 881 N both-way force to push and retract panels with equal momentum.
Textile Loom Beat-Up
Powers a weft insertion cam on a weaving loom, where the rear protruding rod operates a mechanical timing flag while the front rod actuates the reed.
Wafer Cassette Loading
Indexes a 50 mm bore pusher in a semiconductor wafer handler, using the twin-rod geometry to prevent binding during dual-side cassette loading.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X125S the Right Cylinder?
Stepping down to the 40 mm bore yields 528 N at 0.5 MPa, whereas stepping up to the 63 mm bore provides 1457 N at 0.5 MPa—choose the 50 mm bore when your payload requires the 881 N intermediate range. If your application suffers from severe end-of-stroke shock, upgrade to the MBLCD variant for adjustable air cushioning instead of the fixed rubber bumper. Mounting is strictly limited to Basic, FA flange, or LB foot brackets; the MBLD series eliminates back-cover (CA/U) and SDB pivot options due to its through-rod design. To replace this exact unit, match the 50 mm bore, 125 mm stroke, G1/4 port, PT thread, and -S magnet. Remember that this cylinder drifts without live air—the bumper is not a locking device.
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 MBLD50X125S FAQ
Because the double-rod design creates equal annulus areas on both sides, the push and pull forces are identical: 881 N at 0.5 MPa, 1233 N at 0.7 MPa, and a maximum of 180 kgf at 1.0 MPa.
The -S suffix adds a built-in magnet for CMSG reed or DMSG/EMSG electronic sensors to track position. The double-rod layout means a rod exits both ends, allowing you to mount a workpiece on the front and a position flag or cam on the rear, while providing better anti-rotation resistance than a single-rod cylinder.
