The AirTAC AirTAC MBL63X400CA 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 MBL63X400CA is a double-acting aluminum mini round cylinder engineered for heavy-duty clamping in spatially constrained machinery. Operating at 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force across its 400 mm stroke. The CA pivot back cover allows the body to swing on a pin, making it exceptionally well-suited for arcing or angular load applications where rigid fixed mounting would induce binding. As a genuine AirTAC component, it features a riveted rolling-packed barrel that minimizes footprint and weight.
This SKU lacks the -S suffix, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor. To manage end-of-stroke energy, the base MBL relies on a fixed rubber bumper rather than an adjustable cushion. The piston utilizes a heterogeneous two-way seal that retains grease, while the Ø16 mm carbon steel rod features 20 µm hard-chrome plating to resist wear and corrosion in demanding industrial environments.

Provides 1558 N of push force at 0.5 MPa to actuate upper die holders on small press brakes, utilizing the 400 mm stroke to clear deep lower dies during part loading.
Swings heavy lane diverter arms on high-speed packaging conveyors, where the CA pivot back cover accommodates the arcing motion required to redirect 400 mm travel paths.
Raises and lowers 400 mm access gates on automated storage retrieval systems, relying on 2181 N at 0.7 MPa to overcome initial static friction on heavy vertical loads.
When sizing this 63 mm bore actuator, buyers can step down to the 50 mm bore (providing 981 N push at 0.5 MPa) for lighter duties, or recognize that 63 mm is the largest available MBL frame (delivering a maximum theoretical 318 kgf at 1.0 MPa). If your cycle speed creates severe end-impact loads beyond what the fixed rubber bumper can absorb, upgrade to the MBLC variant for adjustable air cushioning. Because the 400 mm stroke leaves the Ø16 mm rod highly exposed, the CA pivot back cover on this specific unit is critical—it allows angular self-alignment to prevent rod-bearing bending. For rigid linear guiding over this length, an external guide rail or the MBLD double-rod anti-rotation type is strongly recommended. Note that a plain MBL does not hold position if air pressure is lost; use a pilot-operated check valve for drop prevention. Replacement match: 63 mm bore, 400 mm stroke, G1/4 port, PT thread, CA back cover, no magnet.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder outputs 1558 N push and 1457 N pull force. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, runs at speeds of 30-800 mm/s, and uses a G1/4 port with an M14x1.5 rod-end thread.
No, because this specific SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG sensor switch. Additionally, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion. If you require electronic position detection and adjustable air cushioning, you must select the MBLC variant with the -S magnet option.
