The AirTAC AirTAC MBL50X50U Mini Cylinder | 50mm Bore 50mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 50mm 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 MBL50X50U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it provides 981 N of push force and 881 N of pull force over a 50 mm stroke. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, creating an exceptionally light assembly that is not designed to be disassembled or rebuilt like a traditional tie-rod cylinder.
This specific SKU features a rigid U flat-end back cover for direct fixed mounting, utilizing a G1/4 port and an M14x1.5 rod-end thread. Because it lacks the -S suffix, this model cannot accept a CMSG, DMSG, or EMSG position sensor. The internal seal is a heterogeneous two-way design that retains grease, paired with a carbon steel piston rod featuring 20 um hard-chrome plating for superior wear resistance.

Uses the 981 N push force at 0.5 MPa to physically divert heavy cardboard cartons off a high-speed sorting line without requiring a full-size ISO cylinder.
Retracts quickly under 881 N of pull force to clear small metal stamping pins from a progressive die bed within a 50 mm clearance window.
Acts as a rigid physical stop for loaded pallets entering a wrapping station, utilizing the fixed U flat-end cover to absorb repeated forward impacts.
Select the 50 mm bore when your application requires the 981 N push force at 0.5 MPa but cannot physically accommodate a larger profile cylinder. If you need less force, stepping down to the 32 mm bore yields 402 N of push force, while stepping up to the 63 mm bore provides 1558 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts; for heavier or faster cycling loads that demand adjustable end-cushioning, specify the MBLC variant.
This SKU features a PT tapered port thread and a U flat-end back cover. It does not hold its position if air pressure is lost, as the rubber bumper is not a locking mechanism. Since this model has no -S magnet, external limit switches must be used for rod position detection.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum theoretical force of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No. This base MBL model uses a fixed rubber bumper that cannot be adjusted, rather than an adjustable air cushion. Additionally, because the model code lacks the -S suffix, it has no internal magnet and cannot be fitted with CMSG, DMSG, or EMSG sensor switches.
