Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X40S
The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X40S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 40mm 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 MBLCD63X40S
The AirTAC MBLCD63X40S is a compact double-acting twin-rod mini cylinder featuring a built-in magnet and an adjustable air cushion at both ends. Because a Ø16 mm rod exits both covers, the effective piston area is identical on extension and retraction, yielding an equal 1457 N of thrust each way at 0.5 MPa. The short 40 mm stroke is tailored for rapid, high-impact strokes where abrupt stops would damage a standard cylinder. The cushion needle valves screw-tune end-of-stroke deceleration to protect the end covers from heavy twin-rod kinetic energy, functioning as a shock absorber rather than a locking brake.
This configuration uses a G1/4 port and an M14x1.5 rod-end thread. The riveted aluminum barrel encloses a grease-retaining two-way piston seal, while the carbon-steel rod features 20 µm hard-chrome plating for wear resistance. The -S code indicates a fitted magnet, enabling position detection via CMSG reed or DMSG and EMSG solid-state switches. Since the rear rod also protrudes 40 mm, you must leave corresponding clearance behind the rear cover for the cam or flag. Mounting is restricted to Basic, FA flange, or LB foot styles, as this body lacks back-cover or SDB pivot options.

| Model | Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X40S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 40 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 MBLCD63X40S Is Used
Injection Mold Ejection
Drives a symmetrical ejector plate in an injection molding cell, using the 1457 N both-way force to strip parts evenly while the adjustable cushion absorbs the sudden halt at 40 mm.
Twin-Rod Pressing Station
Applies 2040 N of pressing force at 0.7 MPa for crimping wire terminals, utilizing the dual protruding rods to mount a secondary cam that triggers a press sensor.
High-Force Diverter Gate
Actuates a heavy diverter flap in a packaging line, where the anti-rotation twin rods keep the gate aligned and the air cushion prevents end-cover damage during rapid cycling.
Is the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X40S the Right Cylinder?
For the MBLCD63X40S, stepping down to the 50 mm bore drops your equal both-way force to 881 N at 0.5 MPa, which is better for lighter fixturing. Stepping up is not possible as 63 mm is the largest MBLCD size, making this the maximum thrust choice at 2040 N at 0.7 MPa. Choose this cushioned MBLCD over the MBLD variant when moving heavy jigs at high speeds, as the fixed bumper on the MBLD cannot absorb the impact energy of a 63 mm bore. If your mechanism only needs single-sided work, the single-rod MBLC offers similar cushioning with half the rod mass. Note that a plain MBLCD cannot hold position mid-stroke without live air pressure; the cushion only decelerates near the end caps. For a direct replacement, match the 63 mm bore, 40 mm stroke, G1/4 port, PT thread, Basic mounting, and -S magnet.
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 MBLCD63X40S FAQ
Because a rod exits both ends, the push and pull forces are equal. It delivers 1457 N at 0.5 MPa and 2040 N at 0.7 MPa in both directions. The maximum theoretical force is 297 kgf at 1.0 MPa.
No. The -S code simply means a magnet is fitted for CMSG reed or DMSG and EMSG electronic sensors to detect position. The adjustable air cushion only decelerates the piston near the end covers; it does not lock. An external locking device is required for mid-stroke holding.
