The AirTAC AirTAC MBL63X80SCA Mini Cylinder | 63mm Bore 80mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 80mm 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 MBL63X80SCA is a double-acting aluminum mini round cylinder engineered for tight machinery spaces. Delivering 1558 N of push force at 0.5 MPa, this 63 mm bore unit is the powerhouse of the MBL family. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lightweight frame that is not designed to be disassembled like bulky tie-rod bodies. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the carbon-steel rod features 20 µm hard-chrome plating to resist wear and corrosion.
This specific SKU features a CA pivot (clevis) back cover that allows the cylinder body to swing on a pin, accommodating arcing and angular motion. The built-in magnet (-S) enables position detection using AirTAC CMSG reed or DMSG/EMSG electronic switches. End-of-stroke deceleration is handled by a fixed rubber bumper, which softens impact but does not lock the rod in place if air pressure is lost.

Drives a high-speed routing spindle gantry in PCB prototyping machines, utilizing the 1558 N push force to cleanly break through panels along an arcing path enabled by the CA pivot cover.
Swings a diverter blade on a packaging conveyor to sort small cartons, where the CA clevis mount absorbs angular side-loads during the rapid 80 mm stroke extension.
Secures the hinged lid of a laboratory centrifuge, using the built-in magnet to confirm lock status via a DMSG solid-state switch before the rotor spins up.
If you need less thrust, stepping down to the 50 mm bore yields 981 N of push at 0.5 MPa; conversely, the 63 mm bore is the largest standard MBL size, offering a maximum theoretical output of 318 kgf at 1.0 MPa. Because this SKU uses a CA pivot back cover, it is ideal for applications requiring lateral swing. For rapid cycling with heavy loads, consider the MBLC variant, which adds an adjustable air cushion to tame end-of-stroke impact. Remember that the fixed rubber bumper on this base MBL only softens end-stroke impact; it will not hold a suspended load if air pressure drops or the valve is centered. Use an external rod lock or pilot-operated check valve for fail-safe position holding.
Quick checklist
This double-acting cylinder has a 63 mm bore and 80 mm stroke. It provides 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 G1/4 port, an Ø16 mm rod with an M14x1.5 thread, and operates at speeds of 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper that cannot be adjusted like a cushion screw; if you need adjustable air cushioning for heavier loads, select the MBLC variant. Additionally, the bumper only softens end-of-stroke impact and does not function as a brake, so the rod will drift if air pressure is lost.
