The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X400 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 400mm 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).
The AirTAC MBLCD63X400 is a compact double-acting twin-rod mini cylinder featuring a 63 mm bore and 400 mm stroke. Because a Ø16 mm piston rod protrudes from both end covers, the effective annulus area is identical on extend and retract, yielding equal force and speed in both directions. You get 1457 N of thrust each way at 0.5 MPa, scaling to 2040 N at 0.7 MPa. The riveted aluminum barrel houses a grease-retaining two-way piston seal, while the carbon-steel rod carries a 20 µm hard-chrome plating to resist wear.
Unlike the base MBLD which relies on a fixed rubber bumper, this model incorporates a screw-tunable adjustable air cushion at both ends. This mechanism lets you dial in end-of-stroke deceleration for heavy 400 mm twin-rod moves, preventing end-cover damage without acting as a mechanical lock. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. Overall length equals A plus 2 x stroke, meaning the rear rod requires substantial clearance to avoid collision.

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.

Drives a 400 mm twin-rod ejection plate on a 200-ton injection molding machine, using the 1457 N bidirectional force to push and pull heavy plastic parts evenly out of the tool cavity.
Acts as a dual-sided anti-rotation stop gate on a heavy-duty pallet conveyor, where the 400 mm stroke clears tall pallets and the adjustable cushion absorbs the 2040 N deceleration impact at 0.7 MPa.
Pushes and retracts a 16 mm guide tube on a CNC lathe bar feeder, using the equal both-way speed to stabilize heavy stock over the 400 mm travel without rotational twist.
Stepping down from this 63 mm bore, the 50 mm variant provides 881 N at 0.5 MPa, which is insufficient if you need to maintain the 1457 N bidirectional thrust. There is no larger bore in the MBLCD mini range, making this the maximum force option. Choose this over the single-rod MBLC when you need a cam or secondary tool on the rear rod, or over the MBLD when your moving mass demands tunable cushioning rather than a fixed bumper. Mounting is strictly limited to Basic, FA flange, or LB foot; there is no SDB pivot or back-cover option. Because this SKU has no -S suffix, it cannot support a position sensor. At 400 mm, the extended twin rods are highly susceptible to side-load bending—always use external linear guides to support the load. Direct drop-in replacements must match the 63 mm bore, 400 mm stroke, G1/4 port, M14x1.5 rod thread, and PT thread form.
Quick checklist
Because a rod exits both ends, the push and pull forces are identical. The MBLCD63X400 generates 1457 N at 0.5 MPa and 2040 N at 0.7 MPa in both directions. The theoretical maximum at 1.0 MPa is 297 kgf.
No. This specific MBLCD63X400 SKU lacks the built-in -S magnet, meaning CMSG reed switches or DMSG/EMSG electronic sensors cannot detect rod position. You would need the MBLCD63X400S variant for position feedback.
