The AirTAC AirTAC MBL50X40U Mini Cylinder | 50mm Bore 40mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 40mm 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 MBL50X40U 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 it well-suited for short 40 mm actuation tasks requiring high thrust. The U suffix indicates a flat-end rear cover, providing a rigid, fixed mounting footprint for straightforward inline pushing. As a genuine AirTAC component, it ensures reliable performance in compact assemblies.
This model features a riveted rolling-packed barrel where the covers are crimped to the tube, yielding a lightweight body that is not designed to be disassembled like a tie-rod cylinder. Internal longevity is maintained by a heterogeneous two-way piston seal that retains grease, while the Ø16 mm carbon-steel piston rod is protected by 20 µm hard-chrome plating for wear resistance. Because this specific SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Provides the 981 N push force required to knock out dense plastic parts from injection molds within a cramped 40 mm stroke envelope.
Actuates a rigid U-mount diverter arm to sort heavy glass beverage containers on a high-speed packaging conveyor.
Applies stable downward clamping pressure on printed circuit board test fixtures where a compact 50 mm bore footprint is mandatory.
At 0.5 MPa, this 50 mm bore generates 981 N of push and 881 N of pull force. If your application requires less force, stepping down to the 40 mm bore yields 628 N push, while moving up to the 63 mm bore provides 1558 N push for heavier loads. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion; choose the MBLC variant if your 40 mm stroke requires precise end-deceleration for heavier moving masses. Additionally, the MBL50X40U cannot hold a load if air pressure is lost—the rod will drift—so an external rod lock or pilot-operated check valve is necessary for fail-safe position holding.
Quick checklist
The MBL50X40U has a 50 mm bore and uses a G1/4 port. It delivers 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum theoretical force of 200 kgf at 1.0 MPa.
No. Because the model code lacks the -S suffix, this specific cylinder does not have a built-in magnet and cannot accommodate CMSG, DMSG, or EMSG sensor switches. You must select an MBL50X40SU variant for position detection.
