The AirTAC AirTAC MBL63X400SU Mini Cylinder | 63mm Bore 400mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 400mm 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 MBL63X400SU is a double-acting aluminum mini round cylinder engineered to deliver substantial thrust within a compact footprint. It yields 1558 N push and 1457 N pull at 0.5 MPa, making this 400 mm stroke variant well-suited for driving heavy slides or actuators across long spans where a profile cylinder would consume too much space. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lighter assembly that is not intended to be rebuilt like a traditional tie-rod body.
This specific SKU incorporates a U flat-end back cover for rigid, fixed mounting and includes a built-in magnet (-S) for position detection. The internal heterogeneous two-way piston seal actively retains grease for long service life, while the carbon-steel piston rod features 20 μm hard-chrome plating to resist wear and corrosion. As a genuine AirTAC component, it operates at speeds from 30-800 mm/s and relies on a fixed rubber bumper to soften end-of-stroke impacts.

Provides the 2181 N push at 0.7 MPa needed to positively eject heavy loaded pallets from a 400 mm long conveyor lane where space restricts larger profile cylinders.
Drives a long-stroke pusher to advance bar stock into the collet, using the -S magnet and a DMSG electronic switch to confirm full 400 mm retraction before the spindle starts.
Raises and lowers stacks of industrial component trays, relying on the 1558 N pull force to lift the weighted carriage while the U flat-end cover secures rigidly to the machine superstructure.
Selecting the MBL63X400SU fits applications demanding the highest standard thrust from the MBL family's 318 kgf maximum at 1.0 MPa. If you need slightly less force, step down to the 50 mm bore, which provides 981 N push at 0.5 MPa; as the largest standard bore, there is no larger step-up within this mini series. Because this 400 mm stroke places considerable leverage on the Ø16 mm rod, you must manage side-load to prevent rod-bearing bending—utilize an external guide mechanism or consider the MBLD double-rod anti-rotation type for stability over the extended length.
This configuration uses a G1/4 port with PT tapered threading, a U flat-end back cover, and an -S magnet for CMSG, DMSG, or EMSG sensor switches. Note that the fixed rubber bumper only softens end impacts and does not lock the rod; if your load must be held without live air pressure, install an external pilot-operated check valve or rod lock. For heavier moving masses that require end-deceleration tuning, specify the MBLC variant for its adjustable air cushion.
Quick checklist
The 63 mm bore generates 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa. It uses a Ø16 mm carbon-steel piston rod with an M14x1.5 rod-end thread.
No, the base MBL63X400SU uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable cushion screw. For heavy moving loads requiring adjustable end-deceleration, you must switch to the MBLC variant which features adjustable air cushioning.
