The AirTAC AirTAC MBL63X300CA Mini Cylinder | 63mm Bore 300mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 300mm 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 MBL63X300CA is a compact double-acting aluminum mini round cylinder engineered to deliver substantial thrust in confined machinery spaces. Operating at 0.5 MPa, it provides 1558 N of push force and 1457 N of pull force, extending 300 mm to drive heavier mechanisms. This genuine OEM unit features a CA pivot (clevis) back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads during operation.
Unlike tie-rod bodies that unbolt for maintenance, this cylinder utilizes a riveted rolling-packed aluminum barrel where the covers are crimped permanently to the tube for a lightweight, space-saving profile. The carbon steel piston rod is treated with a 20 µm hard-chrome plating to resist wear and corrosion, while a heterogeneous two-way piston seal retains internal grease for a long service life. Note that this specific SKU lacks the -S suffix, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Drives heavy metal blanks into a compact stamping press, utilizing the 1558 N push force and CA clevis to absorb angular misalignment during the 300 mm feed arc.
Actuates a diverter arm on a packaging conveyor, where the 300 mm stroke provides full lane separation and the pivot mount handles side-loading from heavy pallets.
Pushes open heavy automated security gates on storage machines, relying on the top-tier 2181 N push at 0.7 MPa to overcome initial friction over the long 300 mm travel.
Selecting the MBL63X300CA is ideal when your application requires the maximum standard bore thrust in the MBL series. If you need slightly less force, stepping down to the 50 mm bore yields 981 N of push at 0.5 MPa; as the largest available bore, 63 mm sits at the top of the range with a maximum theoretical output of 318 kgf at 1.0 MPa. Because this is a 300 mm stroke, the unsupported Ø16 mm rod is highly susceptible to bending under side loads—always utilize the CA pivot back cover with an SDB bracket, add external linear guides, or switch to an MBLD double-rod cylinder to prevent premature seal failure.
Keep in mind the base MBL uses a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable air cushion; choose the MBLC variant if your heavy 300 mm moves require deceleration tuning. Additionally, a plain MBL does not hold its position when air pressure is lost or exhausted—the rod will drift or drop. For critical load-holding safety without live pressure, install an external rod lock or a pilot-operated check valve. Replacement matching requires a 63 mm bore, 300 mm stroke, G1/4 port size, PT thread form, CA back cover, and no magnet.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of 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 at a speed of 30-800 mm/s.
No, this specific SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption, not an adjustable air cushion; you must upgrade to the MBLC variant for adjustable cushioning.
