The AirTAC AirTAC MBL50X30U Mini Cylinder | 50mm Bore 30mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 30mm 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 MBL50X30U is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push force at 0.5 MPa, making this 50 mm bore, 30 mm stroke unit ideal for short, high-impact moves. The U flat-end back cover provides a rigid, fixed rear mounting face for straightforward attachment.
Unlike tie-rod bodies, this cylinder uses a riveted rolling-packed barrel where the covers are crimped to the tube, yielding a light, compact profile that is not designed to be disassembled. It relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion. Note that this specific SKU lacks the -S suffix, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor.

Uses the short 30 mm stroke and 981 N push force to eject plastic parts from molding dies where vertical space is highly restricted.
Quickly diverts cartons on a conveyor using 1374 N at 0.7 MPa, with the U flat-end cover providing rigid mounting against side impact.
Applies precise 881 N pull force to seat electronic boards into test connectors, leveraging the 30 mm stroke for rapid cycling.
At 0.5 MPa, this 50 mm bore generates 981 N of push force. If your application needs less force, step down to the 40 mm bore (628 N push); if you require more power, step up to the 63 mm bore (1558 N push). For this specific U flat-end configuration, the rigid rear mount suits straight-line thrust, but if your mechanism induces arcing or side loads, consider switching to a CA pivot back cover. Because the base MBL uses a fixed rubber bumper, choose the MBLC variant if you need adjustable air cushioning for heavier 1374 N (at 0.7 MPa) payloads.
Remember that a plain MBL does not hold its load if air pressure is lost or the valve is centered; the rod will drift. Use an external pilot-operated check valve if position holding is required. This 30 mm stroke is short enough that the Ø16 mm carbon steel rod resists bending well, but for any stroke over 300 mm, you must add an external guide or switch to the MBLD double-rod anti-rotation type to prevent side-load bearing wear.
Quick checklist
This 50 mm bore cylinder features a G1/4 port and a Ø16 mm rod. At 0.5 MPa it provides 981 N push and 881 N pull force. At 0.7 MPa the push force is 1374 N, and it reaches a maximum theoretical force of 200 kgf at 1.0 MPa.
No, this MBL50X30U SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper, not an adjustable cushion screw; you must upgrade to the MBLC variant for adjustable air cushioning.
