The AirTAC AirTAC MBL50X100U Mini Cylinder | 50mm Bore 100mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 100mm 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 MBL50X100U is a double-acting aluminum mini round cylinder engineered for tight machinery spaces where footprint and weight matter. With a 50mm bore and 100mm stroke, it generates 981 N of push force and 881 N of pull force at 0.5 MPa, peaking at 200 kgf theoretical maximum at 1.0 MPa. The U suffix denotes a rigid flat-end rear cover, providing a solid fixed mounting surface for straight-line thrust applications. This genuine AirTAC unit is not an ISO 15552 profile cylinder; it is a compact, non-standardized unit built for space efficiency.
Inside the riveted rolling-packed aluminum barrel, the cylinder relies on a heterogeneous two-way piston seal that retains grease for long service life. The Ø16 mm carbon-steel piston rod features 20 μm hard-chrome plating to resist wear and corrosion. Because this specific SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG sensor switch for position detection. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable cushion screw.

Handles 981 N of thrust to push heavy cardboard cartons off a high-speed packaging conveyor into a secondary labeling station.
Uses its 100mm stroke and rigid U flat-end mount to drive a small ejection plate inside a tight injection molding machine cavity.
Acts as a robust physical stop for loaded pallets entering a stretch wrapper, absorbing impact with its fixed rubber bumper.
If your application requires less force, step down to the 40mm bore (628 N push @0.5 MPa); if you need more power, the 63mm bore (1558 N push @0.5 MPa) is the next size up. The base MBL uses a fixed rubber bumper for end-of-stroke impact absorption; for faster cycling or heavier loads requiring adjustable air cushioning, specify the MBLC variant. Remember that this cylinder does not hold its load when air pressure is lost or the valve is centered—the rod will drift or drop. Use an external rod lock or pilot-operated check valve if position holding is required.
When replacing this unit, match the 50mm bore, 100mm stroke, G1/4 port size, PT port thread form, U flat-end back cover, and the absence of a built-in magnet. The 100mm stroke is well within the 500mm standard limit, keeping the Ø16mm rod highly stable without requiring external side-load guides.
Quick checklist
At 0.5 MPa, this 50mm bore cylinder provides 981 N push and 881 N pull force. At 0.7 MPa, push increases to 1374 N, with a theoretical maximum of 200 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
No. Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper rather than an adjustable air cushion; choose the MBLC variant if you need adjustable cushioning.
