The AirTAC AirTAC MBL50X50SU Mini Cylinder | 50mm Bore 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 MBL50X50SU is a compact double-acting aluminum mini round cylinder engineered to deliver a push force of 981 N at 0.5 MPa across a 50 mm stroke. Its small footprint and lightweight riveted rolling-packed body make it highly effective for tight machine spaces where larger profile cylinders cannot fit. This specific SKU includes a built-in magnet (-S) for rod position detection and features a U flat-end back cover for rigid fixed mounting.
Unlike tie-rod cylinders, the front and back covers of this body are crimped to the tube, creating a sealed unit not designed for disassembly. The Ø16 mm carbon steel piston rod features 20 um hard-chrome plating for wear resistance, while a heterogeneous two-way piston seal retains grease for extended operational life. Position feedback is achieved via AirTAC CMSG (reed) or DMSG and EMSG (solid-state electronic) sensor switches.

Provides the 981 N push force needed to snap a lightweight conveyor diverting gate into position, while the 50 mm stroke keeps the retracted package size minimal within the conveyor frame.
Holds electronic test fixtures securely against PCBs with precise 50 mm travel, using the built-in magnet to confirm clamp engagement to the PLC before testing begins.
Drives a compact folding arm to tuck minor flaps on packaging lines, where the rigid U flat-end mounting ensures the arm stays perfectly aligned under high-speed cycling.
With a 981 N push force at 0.5 MPa, this 50 mm bore sits comfortably in the mid-range. If your application requires less force, stepping down to the 40 mm bore provides 628 N of push force. Conversely, moving up to the 63 mm bore yields 1558 N for heavier loads. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts; if your cycle rates demand adjustable air cushioning to prevent shock, select the MBLC variant instead.
This model includes a U flat-end back cover and a PT tapered port thread. Because it is a double-acting cylinder, air drives both extension and retraction, but it will not hold a load if air pressure is lost or the valve is centered—you must add an external rod lock or pilot-operated check valve for fail-safe position holding.
Quick checklist
At 0.5 MPa, the push force is 981 N and the pull force is 881 N. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf when operated at the 1.0 MPa pressure limit.
No, the base MBL50X50SU uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable air cushion. If your application requires adjustable cushioning for heavier or faster moving loads, you should select the MBLC variant.
