Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X20S
The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X20S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 20mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 1458 N each way at 0.5 MPa. Adjustable air cushion (both ends).

About the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X20S
The AirTAC MBLCD63X20S is a compact, double-acting double-rod mini cylinder featuring an adjustable air cushion at both ends. Because a Ø16 mm rod extends from both the front and rear covers, the effective piston area is identical in both directions, yielding an equal force of 1457 N each way at 0.5 MPa. The 20 mm stroke is ideal for high-impact, short-travel operations where abrupt stops are common. The built-in magnet (-S) enables position detection using AirTAC CMSG (reed), DMSG, or EMSG (solid-state) switches.
Unlike the base MBLD which relies on a fixed rubber bumper, this model utilizes screw-tunable end-of-stroke deceleration to protect the end covers during heavy, high-velocity cycles. The twin-rod design provides inherent anti-rotation resistance and allows a secondary cam or flag to be mounted on the rear rod. Constructed with a riveted aluminum barrel and a 20 µm hard-chrome plated carbon steel rod, it operates at speeds from 30 to 800 mm/s. Note that the cushion only decelerates the load; it does not lock position, so an external holding device is required if mid-stroke locking is needed.
Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X20S Technical Specifications
| Model | Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X20S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 20 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 | Adjustable air cushion (both ends) |
| 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 (Ø63mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 1458 N |
| 0.7 MPa | 2041 N |
| Max (@1.0 MPa) | 297 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 MBLCD Aluminum Alloy Mini Cylinder MBLCD63X20S Is Used
Punch Press Stripping
Drives a short-stroke stripper plate in a metal stamping line, using the 1457 N both-way force to strip sheet metal from a punch die reliably.
PCB Loader Clamping
Secures heavy copper panels in an automated PCB loading station, utilizing the twin-rod anti-rotation property to keep the clamp perfectly aligned.
Bottle Capper Seating
Snaps plastic caps onto beverage bottles at high speed, relying on the adjustable air cushion to soften the end-of-stroke impact and prevent cap damage.
Is the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X20S the Right Cylinder?
Selecting the MBLCD63X20S provides maximum thrust in a short package. If 1457 N is excessive, stepping down to the 50 mm bore yields 881 N at 0.5 MPa; as this 63 mm bore is the largest in the series, there is no larger option. Compared to the single-rod MBLC, this double-rod variant ensures equal push and pull forces while resisting torsional loads. Mounting is restricted to Basic, FA (flange), or LB (foot); there is no SDB pivot or back-cover option. When replacing this unit, match the 63 mm bore, 20 mm stroke, G1/4 port, default PT thread, and the -S magnet. Despite the short 20 mm stroke, always verify that side loads are minimized through proper external guidance to prevent premature rod seal wear.
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 MBLCD Aluminum Alloy Mini Cylinder MBLCD63X20S FAQ
Because the double-rod design occupies volume on both sides of the piston, extend and retract forces are equal. Output is 1457 N at 0.5 MPa, 2040 N at 0.7 MPa, and a maximum of 297 kgf at 1.0 MPa.
The screw-tunable air cushion allows you to regulate end-of-stroke deceleration, which protects the end covers when moving heavy loads at high speeds. Unlike the fixed rubber bumper on the MBLD, it absorbs kinetic energy without bouncing, though it does not lock the rod in place.
