The AirTAC AirTAC MBL50X40SU Mini Cylinder | 50mm Bore 40mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 40mm 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 MBL50X40SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push and 881 N pull force at 0.5 MPa, making this 50mm bore, 40mm stroke configuration ideal for moving heavier slides or small actuators where footprint matters. The built-in -S magnet enables direct mounting of CMSG reed or DMSG/EMSG electronic sensor switches for precise end-of-stroke detection.
This variant features a U flat-end back cover for rigid, fixed rear mounting. Unlike tie-rod bodies, its riveted rolling-packed barrel permanently crimps the covers to the tube for extreme lightness, while the heterogeneous two-way piston seal retains grease for long service life. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion.

Provides 981 N of push force at 0.5 MPa to eject dense plastic parts from tight mold cavities where a larger profile cylinder would exceed the machine's internal clearances.
Actuates a heavy diverter arm on a 50mm conveyor line, using the built-in -S magnet to trigger a DMSG solid-state sensor and confirm the 40mm stroke position.
Folds heavy corrugated carton flaps in a continuous packaging line, relying on the rigid U flat-end back cover to withstand repeated high-impact lateral folding forces.
For lighter duties requiring only 628 N push at 0.5 MPa, step down to the 40mm bore; for heavier presses needing 1558 N, step up to the 63mm bore. The 50mm bore uses a G1/4 port and an M14x1.5 rod-end thread. Choose the MBLC variant if your application needs adjustable air cushioning for heavier moving masses. If the load must be held mechanically without live air pressure, this cylinder will drift or drop—install an external rod lock or pilot-operated check valve.
With a 40mm stroke, side-load risk is minimal, but always ensure the U flat-end cover and front thread are aligned squarely to avoid rod-bearing wear. This SKU includes the -S magnet for position sensing but uses default PT tapered port threads.
Quick checklist
The 50mm bore generates 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 features a G1/4 port, an M14x1.5 rod-end thread, and a 16mm piston rod.
No, the base MBL50X40SU uses a fixed rubber bumper to absorb end-of-stroke impact and cannot be adjusted. If your application involves fast cycling or heavy loads requiring adjustable end-cushioning, you should select the AirTAC MBLC variant instead.
