Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X15S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X15S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 15mm 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 MBLD50X15S
The AirTAC MBLD50X15S is a double-acting, double-rod aluminum mini cylinder engineered for compact setups needing high force over a very short distance. Because a Ø16 mm 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 it ideal for rapid, symmetrical operations where push and pull dynamics must match perfectly.
The 15 mm stroke keeps the overall envelope extremely tight, while the built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to track piston position. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod provide durable service. A fixed rubber bumper absorbs end-of-stroke impact, and the rear rod can simultaneously drive a secondary mechanism or position flag.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X15S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X15S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 15 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 MBLD50X15S Is Used
PCB Edge Connector Seating
Drives a 15 mm stroke to press mating connectors onto PCB panels with 881 N of equal both-way force, using the rear rod to trigger a proximity flag for cycle counting.
Print Label Splicing
Applies symmetrical push-pull pressure to splice continuous print media webs, leveraging twin rods to prevent blade yaw during the 15 mm cutting and joining motion.
Pharmaceutical Tray Indexing
Shifts lightweight pharmaceutical trays between inspection stations, where the double-rod design ensures the 881 N push and pull speeds remain perfectly balanced to avoid product spillage.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X15S the Right Cylinder?
When sizing this 50 mm bore, 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. Choose the 50 mm when you need robust clamping or lifting power in a tight 15 mm stroke envelope without the bulk of the 63 mm. Unlike the single-rod MBL, this MBLD offers equal force and dual-side anti-rotation guidance. If your application generates heavy end-impact shocks, consider the MBLCD variant, which features adjustable air cushions instead of the standard fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. To replace this unit, match the 50 mm bore, 15 mm stroke, G1/4 port, PT thread, and the -S magnet. Note that a plain MBLD does not hold position without live air—the rod drifts if pressure drops, so an external lock is required for true holding.
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 MBLD50X15S FAQ
Because the MBLD50X15S is a double-rod cylinder, the force is equal in both directions due to matching annulus areas. It generates 881 N at 0.5 MPa and 1233 N at 0.7 MPa in both extend and retract. The maximum theoretical force is 180 kgf at 1.0 MPa.
The twin-rod design allows you to mount a workpiece on one end and a cam, guide, or position flag on the rear protruding rod, improving anti-rotation stability. The -S suffix indicates a built-in magnet, enabling AirTAC CMSG reed switches and DMSG/EMSG electronic sensors to detect rod position. A non-S SKU cannot accept these sensors.
