The AirTAC AirTAC MBL63X15CA Mini Cylinder | 63mm Bore 15mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 15mm 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 MBL63X15CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body will not fit. It delivers a robust 1558 N push force at 0.5 MPa (2181 N at 0.7 MPa) across its 15 mm stroke, making it ideal for high-impact clamping or short ejection tasks. As a genuine AirTAC unit, it features a riveted rolling-packed barrel where the front and back covers are crimped to the tube for a lightweight footprint, though this construction means it is not designed to be disassembled like a tie-rod cylinder.
This specific SKU includes a CA pivot (clevis) back cover that allows the cylinder body to swing on a pin, accommodating arcing or angular loads that would bind a rigid fixed-foot mount. The carbon-steel piston rod is hardened with 20 um chrome plating for wear and corrosion resistance, while the heterogeneous two-way piston seal retains grease for a long service life. Note that because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Uses the 1558 N push force at 0.5 MPa to knock heavy stamped metal blanks out of a die within a tight 15 mm stroke window.
Leverages the CA pivot back cover to swing a diverter arm on a pin, smoothly handling angular loads while routing packages on a conveyor line.
Provides high holding power (up to 318 kgf at 1.0 MPa) to secure circuit board panels during routing, fitting easily into compact electronics assembly machinery.
With a 1558 N push force at 0.5 MPa, stepping down to the 50 mm bore yields 981 N for lighter ejection, while stepping up is not an option as 63 mm is the largest standard MBL size. If your application requires adjustable end-of-stroke cushioning for heavier moving masses, select the MBLC variant instead of the base MBL, which relies solely on a fixed rubber bumper to soften end-stop impact. For single-acting push or pull operations, the MSBL or MTBL variants (available in 20-40 mm bores) are the correct alternatives.
The CA pivot back cover on this unit is specifically designed to handle angular loads, but the 15 mm stroke keeps the rigid side-load risk minimal. Keep in mind that a plain MBL does not hold its position or load when air pressure is lost or the valve is centred; the rod will drift or drop. If your machine requires the load to stay fixed without live pressure, you must add an external rod lock or a pilot-operated check valve to the pneumatic circuit.
Quick checklist
This 63 mm bore cylinder 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, a Ø16 mm rod with an M14x1.5 rod-end thread, and operates at speeds of 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion (you would need the MBLC variant for that). Additionally, this specific SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG electronic position sensor switches.
