The AirTAC AirTAC MBL50X175SU Mini Cylinder | 50mm Bore 175mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 175mm 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 MBL50X175SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push force at 0.5 MPa across its 175 mm stroke, making it well-suited for driving heavier mid-stroke automation sequences. The riveted rolling-packed barrel keeps the overall footprint exceptionally light and compact, though it is not designed to be disassembled and rebuilt like a tie-rod cylinder.
This specific SKU includes a U flat-end back cover for rigid rear mounting and a built-in magnet (-S) for position sensing. The internal two-way piston seal retains grease for long service life, while the carbon-steel piston rod features 20 um hard-chrome plating for wear and corrosion resistance. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion.

Pushes 50kg conveyor pallets laterally at 981 N force, using the 175 mm stroke to clear adjacent transfer lines in packaging machinery.
Drives an electronics test head down onto printed circuit boards, using the built-in magnet to trigger a DMSG solid-state sensor at the exact test position.
Folds heavy corrugated cardboard flaps prior to case sealing, where the 881 N pull force reliably retracts the mechanism against box resistance.
If you need less force, stepping down to the 40 mm bore yields 628 N push at 0.5 MPa, while moving up to the 63 mm bore provides 1558 N. Because this 175 mm stroke is relatively long for a mini cylinder, the Ø16 mm rod has limited side-load tolerance; an external guide or pivot bracket is recommended to prevent rod-bearing bending under offset loads. To manage end-stop shock at higher speeds, consider the MBLC variant which adds an adjustable air cushion. Note that this base MBL does not hold its load when air pressure is lost or exhausted—the rod will drift. Use an external rod lock or pilot-operated check valve if position holding is required. Replacement match: 50 mm bore, 175 mm stroke, G1/4 port, PT thread, U flat-end back cover, magnet included.
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull force. At 0.7 MPa the push force is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, the base MBL50X175SU uses a fixed rubber bumper to absorb end-of-stroke impact. If your application requires adjustable air cushioning for heavier or faster moving loads, you should select the MBLC variant instead.
