The AirTAC AirTAC MBL50X300SCA Mini Cylinder | 50mm Bore 300mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 300mm 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 MBL50X300SCA is a double-acting aluminum mini round cylinder engineered for compact spaces requiring substantial thrust. It generates 981 N of push force and 881 N of pull force at 0.5 MPa, making it well-suited for moving heavier jigs or actuating large clamps over its 300 mm stroke. The riveted rolling-packed barrel keeps the body light and permanently sealed, while the carbon-steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion in harsh industrial environments.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensor switches to track rod position. It is fitted with a CA pivot back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Drives a 300 mm swing arm to divert heavy corrugated cartons between sorting lanes, utilizing the 981 N push force and CA pivot back cover to handle the arcing motion smoothly.
Extends 300 mm to push large plastic automotive interior panels out of an injection molding press, relying on the 1374 N force at 0.7 MPa to break the vacuum of the mold cavity.
Actuates a 300 mm lifting gate to control the flow of palletized goods onto a stretch wrapper, where the CMSG reed sensor switch confirms the gate is fully open before the conveyor advances.
For tasks needing less force, the 40 mm bore neighbor provides 628 N of push at 0.5 MPa, whereas stepping up to the 63 mm bore yields 1558 N for heavier demands. The 300 mm stroke on this 50 mm bore cylinder requires careful mounting; the 16 mm rod has limited side-load tolerance over long extensions, so the CA pivot cover is essential here to absorb angular stress, or you should use an external guide rail to prevent bending. If your cycle time causes severe end-impact, consider the MBLC variant which features an adjustable air cushion. This base MBL configuration uses a G1/4 port with PT thread, an M14x1.5 rod end, and a fixed rubber bumper. Note that the rubber bumper only softens end-stroke impact; it does not hold or lock the load if air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is required for fail-safe positioning.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf (approximately 1962 N) at the 1.0 MPa operating pressure limit.
No, the base MBL50X300SCA uses a fixed rubber bumper to soften the end-of-stroke impact and does not have an adjustable cushion screw. If your application involves high speeds or heavy masses requiring adjustable end-cushioning, you should select the MBLC variant instead.
