The AirTAC AirTAC MBL50X300SU Mini Cylinder | 50mm Bore 300mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 300mm 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 MBL50X300SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body will not fit. It delivers a robust 981 N push force at 0.5 MPa (1374 N at 0.7 MPa) over a 300 mm stroke. The riveted rolling-packed barrel crimps the covers directly to the tube, yielding a lightweight, compact envelope that is not designed to be disassembled like a tie-rod cylinder. This specific SKU includes a U flat-end back cover for rigid mounting and a built-in magnet (-S) for position detection.
Internally, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon-steel piston rod features 20 μm hard-chrome plating for wear and corrosion resistance. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion screw. The integrated magnet allows solid-state DMSG or EMSG electronic switches (or CMSG reed switches) to track rod position precisely along the 300 mm travel.

Uses the 981 N push force at 0.5 MPa to kick folded corrugated board blanks into a sealing jaw on a compact packaging line.
Deploys the 300 mm stroke to index raw bar stock into a collet chuck, fitting within the tight clearance of a sliding headstock enclosure.
Actuates a diverter arm on a low-profile pallet conveyor, relying on the DMSG electronic switch to confirm the 300 mm extension before a layer drops.
At 0.5 MPa, this 50 mm bore generates 981 N push and 881 N pull. If your mechanism requires less force, stepping down to the 40 mm bore yields 628 N push, whereas moving up to the 63 mm bore provides 1558 N push for heavier payloads. Because the stroke is 300 mm, the unsupported Ø16 mm rod has a higher risk of bending under side load; utilize an external guide rail, select a CA pivot back cover for arcing motions, or switch to an MBLD double-rod cylinder to prevent rod-bearing wear. If your process demands end-speed tuning rather than a fixed rubber bumper, select the MBLC adjustable air cushion variant. Note that this cylinder cannot hold a load if air pressure drops or the valve is centred; the bumper softens impact but acts as no brake, so fit an external rod lock or pilot-operated check valve for fail-safe positioning. Replacement match: 50 mm bore, 300 mm stroke, G1/4 port, PT thread, U flat-end back cover, magnet (-S).
Quick checklist
This 50 mm bore cylinder provides 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 operating speed ranges from 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact. It does not feature an adjustable air cushion screw. For adjustable end-position cushioning, you must switch to the MBLC variant.
