The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X350S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 350mm 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 MBLCD63X350S is a compact double-acting double-rod mini cylinder featuring a built-in magnet and an adjustable air cushion at both ends. Because a Ø16 mm rod exits both the front and rear covers, the effective piston area is identical in both directions, yielding an equal extend and retract thrust of 1457 N at 0.5 MPa (2040 N at 0.7 MPa). This 63 mm bore, 350 mm stroke configuration is tailored for heavy-duty sliding or lifting tasks where a single-rod actuator would suffer from rotational play.
The integrated -S magnet enables position detection via CMSG reed or DMSG/EMSG electronic switches. Unlike the base MBLD which relies on a fixed rubber bumper, the screw-tunable air cushion on this unit decelerates heavy 297 kgf loads near the stroke ends, protecting the riveted aluminum covers from impact damage. Note that overall length equals A plus twice the stroke, meaning the rear rod requires substantial clearance to avoid collision during the 350 mm travel.

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 350 mm slide in a servo press, using the 2040 N both-way force to move heavy stamping dies while the twin rod prevents torsional twisting.
Shifts heavy machining pallets between stations, relying on the rear rod to trip a mechanical flag for sequencing while the cushion absorbs the 297 kgf kinetic energy.
Ejects cast metal parts from a mold symmetrically, using the equal extend/retract speed to ensure the part drops without binding over the long stroke.
For sizing context, stepping down to the 50 mm bore drops the both-way force to 881 N at 0.5 MPa, while the 63 mm is the largest available in this series, making it the prime choice for maximum twin-rod thrust. Choose this MBLCD variant over the single-rod MBLC when your mechanism needs dual-side guidance, anti-rotation stability, or a rear rod to mount a cam. Mounting is restricted to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. When replacing, match the 63 mm bore, 350 mm stroke, G1/4 port, PT thread, FA/LB mounting, and the -S magnet.
At 350 mm of travel, the unsupported twin rods are highly susceptible to side-load bending. To manage this, ensure the load is rigidly guided externally and avoid applying lateral moments to the rod ends. The adjustable cushion is strictly for end-of-stroke deceleration and does not lock the load; a separate external locking device is required to hold position without live air pressure.
Quick checklist
Because the double-rod design has a rod on both sides, the push and pull forces are equal: 1457 N at 0.5 MPa, 2040 N at 0.7 MPa, and a maximum theoretical 297 kgf at 1.0 MPa.
The screw-tunable air cushion decelerates heavy loads at the end of the 350 mm stroke, preventing end-cover damage that a fixed rubber bumper cannot absorb. It only cushions; it does not lock the load.
