The AirTAC AirTAC MBL50X500SU Mini Cylinder | 50mm Bore 500mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 500mm 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 MBL50X500SU is a double-acting aluminum mini round cylinder engineered for compact spaces requiring substantial thrust. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa, utilizing a 50 mm bore and a 500 mm stroke. This specific SKU includes a built-in magnet (-S) for non-contact position sensing, allowing integration with AirTAC CMSG reed switches or DMSG and EMSG solid-state electronic sensors. The U suffix denotes a rigid flat-end back cover for secure fixed mounting.
Unlike ISO 6432 stainless steel bodies, this unit utilizes a riveted rolling-packed aluminum barrel that crimps the covers directly to the tube, optimizing weight and footprint. The carbon steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion, while a heterogeneous two-way piston seal retains grease for extended operational life. End-of-stroke impact is absorbed by a fixed rubber bumper, which is not adjustable and does not function as a mechanical lock to hold loads.

Pushes 500 mm to index loaded pallets between conveyor zones, utilizing 981 N of thrust to overcome rolling friction in tight machine footprints.
Extends 500 mm to swing or slide heavy shielded access panels on laboratory centrifuges, using the -S magnet to confirm door closure via a DMSG sensor.
Raises a compact sorting diverter gate 500 mm high in packaging sortation systems, relying on the rigid U flat-end back cover for stable fixed mounting.
This 50 mm bore provides 981 N of thrust at 0.5 MPa. If your application requires less force, step down to the 40 mm bore offering 628 N; if you need to move heavier payloads, step up to the 63 mm bore delivering 1558 N. For applications needing precise end-of-stroke deceleration on heavier masses, consider the MBLC variant which features an adjustable air cushion instead of the standard fixed rubber bumper. If the mechanism must hold position without live air pressure, note that this base MBL will drift; an external rod lock or pilot-operated check valve is required.
At 500 mm of travel, the Ø16 piston rod is highly susceptible to bending under side loads. To prevent premature seal wear and rod bearing failure, pair this cylinder with an external linear guide, or switch to the MBLD double-rod type for inherent anti-rotation. Replacement match: 50 mm bore, 500 mm stroke, G1/4 port, PT thread, U flat-end back cover, magnet included (-S).
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
No, the base MBL50X500SU uses a fixed rubber bumper to soften end-of-stroke impact, which is not adjustable. If you need adjustable air cushioning for heavier loads, select the MBLC variant.
