The AirTAC AirTAC MBL50X350SCA Mini Cylinder | 50mm Bore is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 350mm 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 MBL50X350SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push force at 0.5 MPa and features a 350 mm stroke, making it highly suitable for extending actuators in automated packaging or textile machinery. The riveted rolling-packed barrel keeps the overall footprint minimal while firmly crimping the front and rear covers to the tube for extreme lightness.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position. It is fitted with a CA pivot back cover that swings on a pin to accommodate arcing or angular loads. The carbon-steel piston rod features a 20 um hard-chrome plating for high wear and corrosion resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life. End-of-stroke impact is absorbed by a fixed rubber bumper, which is not an adjustable cushion or a locking mechanism.

Provides the 981 N push force needed to traverse and position yarn guides across a 350 mm track in compact weaving looms, using the CA pivot to absorb angular misalignment.
Extends 350 mm to fold large corrugated flaps on packaging lines, relying on the -S magnet and DMSG sensor to confirm fold completion before the sealing head fires.
Acts as a lightweight 50 mm bore ejector for stamped metal parts in tight robotic cells, swinging slightly on its CA clevis to clear the part as the arm retracts.
If your application requires less force, the adjacent MBL40 bore provides 628 N push at 0.5 MPa; if you need more power, the MBL63 bore steps up to 1558 N push. For faster cycling or heavier moving masses at this 350 mm stroke, consider the MBLC variant, which replaces the fixed rubber bumper with an adjustable air cushion. Because this is a double-acting cylinder, air drives the rod in both directions, but it will not hold a load if air pressure drops or the valve is centered—you must add an external rod lock or pilot-operated check valve for fail-safe position holding.
At 350 mm of travel, the 16 mm rod is highly susceptible to side-load bending. The CA pivot back cover on this model actively helps by allowing the cylinder body to articulate, but you should still use an external guide rail or evaluate the MBLD double-rod anti-rotation type for heavy offset loads. Replacement matches require a 50 mm bore, 350 mm stroke, G1/4 port, PT thread, CA pivot back cover, and the -S magnet.
Quick checklist
This 50 mm bore double-acting cylinder provides 981 N push and 881 N pull at 0.5 MPa, and 1374 N push at 0.7 MPa, with a maximum theoretical force of 200 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
No, the base MBL50X350SCA uses a fixed rubber bumper to soften end-of-stroke impacts and cannot be adjusted. If you need adjustable air cushioning for heavier loads, you must select the MBLC variant.
