The AirTAC AirTAC MBL63X75U Mini Cylinder | 63mm Bore 75mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 75mm 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 MBL63X75U is a double-acting aluminum mini round cylinder engineered to deliver substantial thrust in tight machine envelopes. At 0.5 MPa it generates 1558 N of push force and 1457 N of pull force, making this 63 mm bore, 75 mm stroke unit ideal for moving heavy small-format payloads. The U suffix designates a flat-end rigid back cover for stable, fixed mounting.
Unlike tie-rod bodies that unbolt for maintenance, this cylinder uses a riveted rolling-packed aluminum barrel that permanently crimps the covers to the tube for a lighter, compact profile. The carbon-steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion valve. Note that this specific SKU lacks the -S magnet suffix, so it cannot accept a CMSG, DMSG, or EMSG position sensor.

Secures heavy populated PCB panels during conveyor transfer, using the 1558 N push force to lock 75 mm travel fixtures without slipping.
Drives the folding jaws on compact packaging machines, where the 1457 N pull force reliably snaps corrugated blanks into square form.
Ejects dense machined metal bushings from a press die, utilizing the 75 mm stroke to clear the lower tooling safely.
Stepping down to the 50 mm bore reduces thrust to 981 N push at 0.5 MPa, whereas no larger standard MBL bore exists, making this 63 mm the top force option in the mini series. If your assembly requires softer end-stopping for heavy masses, specify the MBLC variant for its adjustable air cushion. For single-direction spring-return tasks, consider the MSBL or MTBL single-acting types.
Because the U-type flat-end back cover provides a rigid rear mount, side loads must be kept minimal given the 16 mm rod diameter. The fixed rubber bumper softens impact but provides no locking force; the rod will drift if air pressure is lost or exhausted. Always use an external pilot-operated check valve if the load must hold position without live pressure.
Quick checklist
At 0.5 MPa this 63 mm bore cylinder provides 1558 N push and 1457 N pull force. At 0.7 MPa the push force reaches 2181 N, with a maximum theoretical force of 318 kgf at 1.0 MPa. The port size is G1/4.
No, this specific SKU lacks the -S suffix, meaning it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. You must select an MBL63X75S model to enable position detection.
