The AirTAC AirTAC MBL50X20SCA Mini Cylinder | 50mm Bore 20mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 20mm 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 MBL50X20SCA 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 a 1374 N push at 0.7 MPa, making this 20 mm stroke variant ideal for high-impact short-travel operations. The riveted rolling-packed aluminum barrel keeps the body light and permanently sealed, though it is not designed to be disassembled like a tie-rod cylinder.
This specific SKU includes a CA pivot (clevis) back cover that swings on a pin to accommodate arcing and angular loads, plus a built-in magnet (-S) for position detection. The rod is carbon steel with 20 μm hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for long service life. It uses a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion.

Related variants: MBLC (adjustable cushion), MBLD (double rod), MBLJ (adjustable stroke), MSBL/MTBL (single acting).
Uses the 981 N push force to knock stamped metal parts out of a die, where the CA pivot absorbs the slight angular offset of the ejection arm.
Swings a diverter blade on a packaging line over a 20 mm stroke, relying on the built-in magnet to confirm arm position for the PLC.
Acts as a short-stroke stop gate for incoming pallets, using the 1374 N push at 0.7 MPa to halt momentum while the clevis mount handles side-play.
If you need slightly less force, step down to the 40 mm bore (628 N push at 0.5 MPa), or step up to the 63 mm bore (1558 N push at 0.5 MPa) for heavier loads. Choose the MBLC variant if your cycle speeds require an adjustable air cushion instead of the standard fixed rubber bumper. Because this is a double-acting cylinder, it will not hold a load if air pressure is lost—you must add an external rod lock or pilot-operated check valve for fail-safe positioning.
This model matches a 50 mm bore, 20 mm stroke, G1/4 port size, PT thread form, CA pivot back cover, and a built-in magnet. The -S magnet enables precise end-of-stroke sensing using AirTAC CMSG (reed) or DMSG and EMSG (solid-state) electronic switches.
Quick checklist
The 50 mm bore yields 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. It operates at 30-800 mm/s, uses a G1/4 port, and features a Ø16 mm rod with an M14x1.5 thread.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact. If your application requires adjustable air cushioning for heavier or faster moving loads, you should select the MBLC variant instead.
