Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X350S
The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X350S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 350mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 881 N each way at 0.5 MPa. Adjustable air cushion (both ends).

About the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X350S
The AirTAC MBLCD50X350S is a compact double-acting mini cylinder featuring a twin-rod design with an adjustable air cushion at both ends. Because a Ø16 mm rod exits both covers, the effective annulus area is identical in each direction, yielding exactly 881 N of force at 0.5 MPa on both extend and retract. The 350 mm stroke suits extended-travel pick-and-place or wide-span lifting tasks. The built-in magnet (-S) enables position detection via CMSG reed or DMSG/EMSG electronic switches.
Screw-tunable end-of-stroke deceleration protects the end covers on heavy twin-rod moves, outperforming the fixed bumper found on the base MBLD. The riveted aluminum barrel and hard-chrome plated carbon-steel rod provide rigid, anti-rotation guidance. Since the rear rod protrudes during operation, you must leave clearance equal to the stroke length behind the cylinder.

| Model | Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X350S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 350 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 (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 MBLCD Aluminum Alloy Mini Cylinder MBLCD50X350S Is Used
Long-Stroke Gripper Transfer
Moves wide automotive stampings between CNC stations using 881 N of equal both-way force, while the twin rods prevent jaw rotation over the 350 mm span.
Textile Beam Indexing
Shifts heavy fabric beams laterally across a weaving loom, relying on the adjustable air cushion to smoothly decelerate the 350 mm traverse without slamming.
Dual-Side Labeling Cam
Uses the rear protruding rod to trigger a mechanical flag for a packaging line, while the front rod applies 1233 N at 0.7 MPa to press labels onto cartons.
Is the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X350S the Right Cylinder?
This 50 mm bore provides 881 N both ways at 0.5 MPa. If your payload is lighter, step down to the 40 mm bore (528 N); for heavier drives, step up to the 63 mm bore (1457 N). Choose this MBLCD variant over the single-rod MBLC when you need dual-side guidance, a rear cam/flag, or strict anti-rotation. Mounting is limited to Basic, FA flange, or LB foot—there is no back-cover or SDB pivot option. The port is G1/4 with an M14x1.5 rod thread.
At 350 mm of travel, the protruding rods are susceptible to bending under lateral loads. Use external linear guides to support the workpiece and prevent rod binding. Remember that the adjustable cushion only decelerates the load near the end caps; it is not a lock, so the cylinder will drift if air pressure drops. For exact replacement matching, verify the 50 mm bore, 350 mm stroke, PT thread, 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 MBLCD50X350S FAQ
Because a rod exits both ends, the push and pull forces are equal. It delivers 881 N at 0.5 MPa and 1233 N at 0.7 MPa in both directions. The maximum theoretical force is 180 kgf at 1.0 MPa.
No. The adjustable air cushion only provides screw-tunable deceleration near the end covers to protect against impact; it is not a lock. The rod will drift without live air pressure. The -S magnet allows CMSG, DMSG, or EMSG sensors to verify end-of-stroke position.
