The AirTAC AirTAC MBL63X50SU Mini Cylinder | 63mm Bore 50mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 50mm 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 MBL63X50SU is a compact double-acting aluminum mini round cylinder engineered to deliver substantial thrust in tight machine spaces. Operating at 0.5 MPa, it provides 1558 N of push force and 1457 N of pull force, making this 63 mm bore, 50 mm stroke variant ideal for heavy-duty clamping and short-stroke ejection. As a non-ISO specialty cylinder, its core advantage is a small footprint and low weight rather than standardized interchangeability.
This specific SKU includes a built-in magnet (-S) for direct position feedback via AirTAC CMSG reed or DMSG/EMSG electronic switches, and features a U flat-end rear cover for rigid fixed mounting. The body utilizes a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, ensuring a lightweight, permanently sealed assembly that is not designed to be disassembled like a tie-rod cylinder. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon-steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion.

Provides the 1558 N push force required to knock finished plastic parts out of tight injection molding tooling spaces where larger cylinders cannot fit.
Acts as a heavy-duty stop block for loaded pallets on a 50 mm stroke, using its rigid U flat-end rear cover to anchor firmly against high impact loads.
Uses the built-in -S magnet with a DMSG electronic switch to confirm exact 50 mm extension when pressing connectors into printed circuit boards.
Selecting this 63 mm bore model is appropriate when your application requires up to 1558 N of push force at 0.5 MPa but lacks the physical space for a larger ISO 15552 profile cylinder. If you need to step down in force, the neighboring 50 mm bore offers 981 N of push at 0.5 MPa; stepping up is not possible within the MBL family as 63 mm is the largest available bore. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts, so if your short-stroke cycle requires adjustable air cushioning to absorb heavier kinetic energy, you should upgrade to the MBLC variant.
For replacement matching, verify the 63 mm bore, 50 mm stroke, G1/4 port size, and default PT tapered port thread. This SKU features the U flat-end back cover and includes the -S magnet for sensor compatibility. Because the MBL is a double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered—the rod will drift. An external rod lock or pilot-operated check valve is required for fail-safe position holding.
Quick checklist
At 0.5 MPa, the MBL63X50SU delivers 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
No, the base MBL63X50SU uses a fixed rubber bumper to soften the end-of-stroke impact, not an adjustable cushion screw. If your application requires adjustable air cushioning for heavier or faster moving loads, you must use the MBLC variant.
