The AirTAC AirTAC MBL63X125CA Mini Cylinder | 63mm Bore 125mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 125mm 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 MBL63X125CA is a double-acting aluminum mini round cylinder engineered for tight machine spaces where high thrust is required. It delivers a robust 1558 N push force at 0.5 MPa and 2181 N at 0.7 MPa, making this 125 mm stroke unit ideal for moving heavy jigs or executing firm press operations. The riveted rolling-packed barrel keeps the body exceptionally light and compact, though it is not designed to be disassembled like a traditional tie-rod cylinder.
This specific SKU features a CA pivot back cover, allowing the cylinder to swing on a pin to accommodate arcing and angular loads. The carbon steel piston rod utilizes a 20 um hard-chrome plating for superior wear resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life. Because this configuration lacks the -S suffix, it cannot support a CMSG, DMSG, or EMSG position sensor.

Uses the 1558 N push force at 0.5 MPa to reliably knock out heavy stamped metal blanks from a progressive die bed.
The CA pivot back cover swings freely on a pin to smoothly articulate a conveyor diverter arm through a 125 mm arc.
Drives a 125 mm stroke folding mechanism to tuck heavy corrugated cardboard flaps on high-speed packaging lines.
Selecting this 63 mm bore model makes sense when your application demands substantial force, offering 1558 N push at 0.5 MPa. If you need slightly less force, step down to the 50 mm bore which provides 981 N push, or step up to a larger ISO 15552 profile cylinder if your spatial constraints loosen. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for heavier, faster cycling loads, choose the MBLC variant which features an adjustable air cushion.
With a 125 mm stroke, the Ø16 mm rod is moderately supported, but if side loads are present, the CA pivot cover on this unit helps absorb angular stress. Remember that a standard MBL does not hold its load when air pressure is lost or exhausted—the rod will drift. If you need position holding without live pressure, install an external rod lock or a pilot-operated check valve. This SKU uses a G1/4 port with PT thread form, an M14x1.5 rod-end, and no magnet.
Quick checklist
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force reaches 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
This specific SKU lacks the -S suffix, so it cannot accept a CMSG, DMSG, or EMSG sensor switch. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; if you need adjustable air cushioning, you must select the MBLC variant.
