The AirTAC AirTAC MBL63X15SU 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 MBL63X15SU is a double-acting aluminum mini round cylinder engineered for high-impact clamping in severely space-constrained machinery. Delivering a robust 1558 N of push force at just 0.5 MPa, this 63 mm bore unit features an ultra-short 15 mm stroke for rapid, high-force end moves. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight, compact body that is not designed to be disassembled like a traditional tie-rod cylinder. This specific SKU includes a U flat-end back cover for rigid, fixed mounting and a built-in -S magnet for position sensing.
Because this is the largest bore in the MBL family, it relies on a heterogeneous two-way piston seal that retains grease for long service life, paired with a carbon-steel piston rod hardened with 20 μm chrome plating to resist wear and corrosion. The integrated magnet allows you to mount CMSG reed or DMSG/EMSG solid-state sensor switches directly to the body for precise end-of-stroke detection. As a base MBL model, end-of-travel deceleration relies on a fixed rubber bumper rather than an adjustable cushion screw.

Uses the 1558 N push force to knock out dense plastic parts from tight mold cavities where a standard profile cylinder body would collide with the tie-bars.
Leverages the ultra-short 15 mm stroke to rapidly compress and seat microchips into sockets on a high-speed assembly line without overshoot.
Provides a heavy-duty 1457 N pull force to snap a heavy steel diverter gate shut on a packaging conveyor, fitting within the machine's narrow side frame.
Selecting this 63 mm bore provides maximum thrust for the MBL line, generating 1558 N push and 1457 N pull at 0.5 MPa. If you need slightly less force to prevent crushing delicate parts, step down to the 50 mm bore, which yields 981 N of push force. Stepping up beyond this size requires transitioning out of the mini round format to a larger profile cylinder. The fixed rubber bumper softens end-stroke impact but provides no position holding; if air pressure drops, the rod will drift and the load will drop, requiring an external pilot-operated check valve for safety.
This SKU is configured with PT tapered port threads, a U flat-end rigid back cover, and a built-in magnet. The short 15 mm stroke keeps the Ø16 mm rod highly stable, minimizing side-load bending risks even under heavy impact loads.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N push and 1457 N pull force. Increasing pressure to 0.7 MPa yields 2181 N push force, with a maximum theoretical limit of 318 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact and cannot be adjusted. If your 15 mm stroke application generates severe shock loads, upgrade to the MBLC variant, which features an adjustable air cushion.
