The AirTAC Airtac MBL Aluminum Alloy Mini Cylinder MBL40X50SCA is a genuine double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 50mm stroke, 1/8" air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL40X50SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 628 N push and 528 N pull force at 0.5 MPa, making it ideal for short 50 mm strokes requiring substantial clamping authority. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight footprint that is not designed to be disassembled like a traditional tie-rod body.
This specific SKU includes a built-in -S magnet for rod position detection via CMSG reed or DMSG and EMSG solid-state switches. It features a CA pivot back cover that swings on a pin to accommodate arcing or angular loads. The carbon-steel piston rod is hardened with 20 um chrome plating for superior wear and corrosion resistance, while the heterogeneous two-way piston seal retains grease for a long service life.

Related variants: MBLC (adjustable cushion), MBLD (double rod), MBLJ (adjustable stroke), MSBL/MTBL (single acting).
Uses the 628 N push force at 0.5 MPa to knock small stamped metal components out of a progressive die, where the CA pivot absorbs the slight angular offset of the ejection arm.
Secures delicate printed circuit boards during routing operations; the -S magnet triggers a DMSG electronic sensor to confirm the clamp is fully engaged before the spindle starts.
Folds minor corrugated carton flaps at high speed, relying on the 528 N retract force and the compact riveted aluminum body to fit within a narrow packaging machine frame.
Select this 40 mm bore when your application requires more power than the 32 mm bore (402 N push at 0.5 MPa) but lacks the physical space for a 50 mm bore (981 N push at 0.5 MPa). The CA clevis mount is optimal for mechanisms requiring pivotal rod-end movement rather than a rigid fixed plane. If your cycle speeds generate destructive end-of-stroke impacts, step up to the MBLC variant which replaces the fixed rubber bumper with an adjustable air cushion.
Keep in mind that the standard MBL rubber bumper softens impact but does not lock the rod; if air pressure drops, the load will drift and drop, requiring an external pilot-operated check valve for position holding. To replace this exact unit, match the 40 mm bore, 50 mm stroke, 1/8" port, PT thread form, CA pivot back cover, and the -S magnet.
Quick checklist
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa the push increases to 880 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
No, the base MBL features a fixed rubber bumper that cannot be adjusted. If your application requires adjustable end-of-stroke deceleration for heavier moving loads, you must use the MBLC variant which incorporates an adjustable air cushion.
