Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X75S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X75S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 75mm 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 MBLD50X75S
The AirTAC MBLD50X75S is a double-acting, double-rod aluminum mini cylinder engineered for symmetrical motion. Because a Ø16 mm rod protrudes from both end covers, the annulus piston area is identical on extension and retraction. This yields exactly 881 N of force each way at 0.5 MPa, ensuring perfectly balanced push and pull dynamics. The 75 mm stroke suits mid-length transfer and indexing tasks. A built-in magnet (-S) enables position detection.
Two distinct advantages emerge from this architecture. First, the rear rod serves as a secondary mounting point for a cam or position flag, allowing you to drive a secondary mechanism or sensor setup directly from the back end. Second, the twin-rod layout inherently resists torsional loads better than a single-rod cylinder, keeping light guided loads from twisting. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod ensure durability, while the fixed rubber bumper softens end-of-travel impact.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X75S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X75S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 75 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 MBLD50X75S Is Used
Turret Lathe Indexing
Drives a multi-station tool turret on a CNC lathe, using the 881 N bidirectional force to positively lock and unlock tool positions without rotational play.
PCB Stacking Lift
Actuates a dual-sided lift pin in a circuit board assembly line, using the rear rod end to trigger a reed CMSG switch for precise stack-height confirmation.
Glass Edge Guide
Maintains straight travel of a glass panel through a grinding station, using the twin rods to prevent torsional twisting of the edge-guide flap under side load.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X75S the Right Cylinder?
When sizing this 50 mm bore, stepping down to the MBLD40X75S yields 528 N both ways at 0.5 MPa, whereas stepping up to the MBLD63X75S provides 1457 N. Choose the 50 mm bore when your application demands roughly 881 N of balanced, dual-directional thrust. If your mechanism suffers from severe end-impact shock at high cycling speeds, step up to the MBLCD variant, which replaces the fixed rubber bumper with an adjustable air cushion.
Mounting is restricted to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option for the double-rod series. Remember that the overall length equals the base body length plus twice the stroke (150 mm total protrusion), so you must leave rear-rod clearance. A plain MBLD does not hold position without live air—the bumper is not a lock. To replace this unit, match the 50 mm bore, 75 mm stroke, G1/4 port, default PT thread, and the -S magnet specification.
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 MBLD50X75S FAQ
Because a rod occupies both sides of the piston, the effective area is equal in both directions. The output force is 881 N at 0.5 MPa and 1233 N at 0.7 MPa, with a maximum theoretical output of 180 kgf at 1.0 MPa. Push and pull forces are identical.
Unlike a single-rod cylinder, the MBLD50X75S has a rod exiting both ends, providing equal extend/retract force and speed, plus a rear rod for mounting a cam or flag. The -S code means a built-in magnet is fitted, allowing AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensors to detect piston position.
