The AirTAC AirTAC MBL63X15U 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 MBL63X15U is a double-acting aluminum mini round cylinder engineered for high-force actuation in confined machinery spaces. With a 63mm bore and 15mm stroke, it generates 1558N of push force and 1457N of pull force at 0.5 MPa, making it the most powerful option in the MBL family for short, heavy-duty clamping or ejection tasks. The U flat-end back cover provides a rigid, fixed rear mounting surface for straightforward inline installation.
Unlike tie-rod cylinders, this unit features a riveted rolling-packed aluminum barrel that crimps the front and rear covers to the tube, resulting in a lighter, more compact footprint that cannot be disassembled for rebuilding. Internal longevity is ensured by a heterogeneous two-way piston seal that retains grease, while the Ø16mm carbon-steel piston rod is protected by a 20µm hard-chrome plating to resist wear and surface corrosion. This specific SKU lacks the -S magnet suffix, so it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Provides 1558N of push force at 0.5 MPa to eject dense stamped metal parts from a progressive die in a fraction of a second.
Acts as a rigid inline stop for heavy-loaded pallets on a packaging conveyor, using the short 15mm stroke to halt movement instantly.
Applies 2181N of force at 0.7 MPa to press thick multi-layer printed circuit boards into aluminum enclosures within a tight assembly jig.
As the largest bore in the series, the MBL63X15U delivers 1558N of thrust at 0.5 MPa (2181N at 0.7 MPa). If your application requires slightly less force, stepping down to the 50mm bore yields 981N of push force while saving valuable mounting space. Because this 15mm stroke is very short, side-load stress on the rod bearing is minimal, though the small 16mm rod diameter still means external guides are recommended if the load is not perfectly aligned. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for faster cycling or heavier moving masses, consider the MBLC variant which features an adjustable air cushion. Note that this plain MBL does not hold its load if air pressure is lost or exhausted—the rod will drift—so an external pilot-operated check valve or rod lock is required for fail-safe position holding. Replacement matching requires a 63mm bore, 15mm stroke, G1/4 port size, PT thread form, U flat-end back cover, and no magnet.
Quick checklist
The 63mm bore provides 1558N of push force and 1457N of pull force at 0.5 MPa, scaling to 2181N push at 0.7 MPa, with a theoretical maximum of 318 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa, runs at speeds of 30-800 mm/s, and uses a G1/4 port with an M14x1.5 rod-end thread.
No, the base MBL63X15U uses a fixed rubber bumper that cannot be adjusted; if you need adjustable air cushioning for heavier loads, you must switch to the MBLC variant. Additionally, this specific SKU lacks the -S suffix, meaning no internal magnet is installed and it cannot accept CMSG, DMSG, or EMSG sensor switches for position detection.
