The AirTAC AirTAC MBL63X350CA Mini Cylinder | 63mm Bore 350mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 350mm stroke, G1/4 air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL63X350CA is a double-acting aluminum mini round cylinder engineered for heavy-duty pushing within confined machinery envelopes. Operating at 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force, scaling up to 2181 N at 0.7 MPa. The 350 mm stroke handles extended travel paths without requiring a full-size ISO 15552 profile body. A CA pivot clevis back cover is integrated directly into the rear head, allowing the cylinder to swing freely on a pin to absorb angular misalignment during arcing motions.
This configuration uses a G1/4 port and a Ø16 mm carbon steel piston rod plated with 20 µm hard chrome to resist wear and corrosion. The riveted rolling-packed barrel crimps the front and rear covers to the tube, yielding a lightweight assembly that is not designed for field disassembly. Because this SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion screw.

Swings large packaging pallets across a belt using the 1558 N push force, with the CA clevis accommodating the arc of the diverter arm.
Kicks heavy stamped metal parts out of a hydraulic press over the 350 mm travel, relying on 2181 N at 0.7 MPa to overcome tooling friction.
Pushes totes from high-speed sortation lines where the 318 kgf maximum theoretical force clears accumulated product jams.
Stepping down in force, the neighbouring 50 mm bore provides 981 N of push at 0.5 MPa, while stepping up beyond this 63 mm bore requires migrating to a larger SAI ISO 15552 profile cylinder. If your sequence demands end-of-stroke speed tuning for heavy moving masses, select the MBLC variant for its adjustable air cushion instead of the fixed rubber bumper found here. Keep in mind the bumper only softens impact; it is not a braking device, so an external rod lock or pilot-operated check valve is required to hold a load safely if air pressure is lost.
With a 350 mm stroke on a 16 mm rod, side-load tolerance is minimal. Long unsupported mini rods bend under lateral stress, so utilize the CA pivot back cover with an SDB bracket or add an external guide rail to prevent rod-bearing damage.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder outputs 1558 N push and 1457 N pull. At 0.7 MPa, push force reaches 2181 N, with a maximum theoretical limit of 318 kgf at 1.0 MPa. It uses a Ø16 mm rod with an M14x1.5 rod-end thread and a G1/4 port.
This specific SKU has a fixed rubber bumper and cannot be adjusted for cushioning; you would need the MBLC variant for an adjustable air cushion. Additionally, because it lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG sensor switches for rod position detection.
