The AirTAC AirTAC MBL63X350SCA Mini Cylinder | 63mm Bore 350mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 350mm 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 MBL63X350SCA is a double-acting aluminum mini round cylinder engineered for heavy-duty actuation within confined machinery footprints. At its core, this 63 mm bore unit generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, making it well-suited for moving substantial loads across its 350 mm stroke. The riveted rolling-packed barrel construction keeps the overall body exceptionally light and compact, distinguishing it from bulky tie-rod alternatives.
This specific SKU incorporates a built-in magnet (-S) for non-contact position detection via AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches. It is configured with a CA pivot back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads. The carbon-steel piston rod features a 20 um hard-chrome plating for superior wear resistance, paired with a heterogeneous two-way piston seal that retains lubricant for an extended service life.

Leveraging the 1558 N push force at 0.5 MPa, this cylinder redirects heavy pallets on 350 mm strokes while the CA pivot absorbs the lateral misalignment of the transfer arm.
The built-in -S magnet enables DMSG solid-state sensors to confirm mold ejection position, while the 20 um chrome-plated rod withstands repetitive high-impact ejection cycles.
Provides the robust 2181 N thrust at 0.7 MPa needed to clamp heavy metal blanks in automated press lines, where the compact riveted barrel fits into tight tooling spaces.
Selecting this 63 mm bore model is appropriate when your application requires substantial thrust, such as the 2181 N output at 0.7 MPa. If you need less force, stepping down to the 50 mm bore provides 981 N of push at 0.5 MPa, while no larger standard MBL bore exists above 63 mm. Because this SKU features a CA clevis rear, it is specifically chosen for mechanisms requiring angular alignment during the stroke cycle. The standard port size is G1/4 with a PT thread form, and the rod-end thread is M14x1.5.
With a 350 mm stroke, the Ø16 mm piston rod is highly susceptible to bending under side loads. The CA pivot back cover helps mitigate this by absorbing angular stress, but an external guide rail or transitioning to an MBLD double-rod cylinder is strongly recommended to prevent rod-bearing wear. Note that the base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts; if your moved mass requires deceleration control, upgrade to the MBLC variant for adjustable air cushioning. Furthermore, this cylinder will not hold a load if air pressure is lost—deploy an external rod lock or pilot-operated check valve for fail-safe positioning.
Quick checklist
This 63 mm bore cylinder delivers a push force of 1558 N and a pull force of 1457 N at 0.5 MPa. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at the 1.0 MPa operating pressure limit.
No, the base MBL features a fixed rubber bumper that softens end-of-stroke impact but cannot be adjusted. For heavy loads requiring controlled deceleration over the 350 mm stroke, the MBLC variant with adjustable air cushioning is required.
