The AirTAC AirTAC MBL50X500SCA 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 MBL50X500SCA is a double-acting aluminum mini round cylinder engineered for compact machinery where a large 50mm bore is required to generate substantial force within a limited footprint. Operating at 0.5 MPa, it provides 981 N of push force and 881 N of pull force, extending across a 500mm stroke. This specific SKU includes a built-in magnet (-S) for non-contact position detection, seamlessly supporting AirTAC CMSG reed switches alongside DMSG and EMSG solid-state electronic sensors. The CA pivot back cover allows the body to swing on a clevis pin, accommodating arcing or angular loads during travel.
Unlike tie-rod cylinders, the MBL features a riveted rolling-packed aluminum barrel that crimps the front and rear covers directly to the tube, minimizing weight and spatial footprint. The piston utilizes a heterogeneous two-way seal designed to retain grease for long service life, while the Ø16mm carbon steel rod is protected by 20µm hard-chrome plating to resist wear and corrosion. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion screw, meaning the MBLC variant should be specified if your application demands softer, tunable end-stroke damping.

Drives a long-reach spot welding head in automotive body-in-white assembly. The 981 N thrust at 0.5 MPa handles the electrode clamping, while the CA clevis allows the cylinder to articulate smoothly with the robot arm's arcing path.
Pushes heavy corrugated cartons onto a palletizing conveyor lane. The 500mm stroke clears the full pallet width, and the DMSG solid-state sensor tracks the fully extended position to confirm carton discharge before retraction.
Diverts heavy fabric rolls between processing stations. The 50mm bore provides enough push force to redirect the rolls against guide rails, and the riveted aluminum barrel keeps the actuator weight low on the overhead swing-frame.
This 50mm bore is a significant step up from the 40mm bore (which yields 628 N push at 0.5 MPa) and sits just below the 63mm bore (delivering 1558 N push at 0.5 MPa), allowing you to size up or down based on your exact dynamic load requirements. If your machine layout requires the rod to return via spring force without continuous air pressure, consider the MSBL or MTBL single-acting versions, though these are only available in 20-40mm bores. For heavier, faster moving loads at this 500mm stroke length, the MBLC variant offers adjustable pneumatic cushioning to prevent hard end-cap impacts.
Because this model utilizes the maximum standard stroke of 500mm on a Ø16mm rod, side-load tolerance is low and the unsupported rod is highly susceptible to bending. The included CA pivot back cover is essential for angular movements, but you should still incorporate an external linear guide or transition to an MBLD double-rod cylinder to prevent rod-bearing damage. Furthermore, a plain MBL does not hold its load if air pressure is lost or the valve is centered; the rod will drift. For fail-safe load holding, integrate an external rod lock or a pilot-operated check valve. Replacement parts must match the 50mm bore, 500mm stroke, G1/4 port size, PT thread form, CA back cover, and -S magnet configuration.
Quick checklist
The 50mm bore generates 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. The 500mm stroke on this unit is the maximum standard stroke available for the MBL series; any stroke beyond 500mm up to 800mm requires a special made-to-order request.
No, the base MBL50X500SCA uses a fixed rubber bumper to soften the end-of-stroke impact and does not feature an adjustable cushion screw. If your application involves high speeds or heavy masses requiring tunable pneumatic damping, you should select the MBLC variant, which includes an adjustable air cushion.
