The AirTAC AirTAC MBL63X20SU Mini Cylinder | 63mm Bore 20mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm 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 MBL63X20SU is a double-acting aluminum mini round cylinder engineered to deliver substantial thrust in a compact footprint. It provides 1558 N of push force and 1457 N of pull force at 0.5 MPa, making this 20 mm stroke variant ideal for high-impact short clamping or ejection tasks. The riveted rolling-packed barrel design permanently crimps the front and rear covers to the tube, yielding a lightweight body that fits into tight machine cavities where larger profile cylinders cannot.
This specific SKU features a U flat-end back cover for rigid, fixed mounting and a built-in magnet (-S) for position feedback. The rod is carbon steel with 20 um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for extended operational life. A fixed rubber bumper absorbs end-of-stroke impact; for adjustable air cushioning, the MBLC variant is required.

Related variants: MBLC (adjustable cushion), MBLD (double rod), MBLJ (adjustable stroke), MSBL/MTBL (single acting).
Supplies 1558 N of push at 0.5 MPa to knock out dense plastic parts from tight mold cavities where a standard 20 mm stroke is sufficient.
Locks heavy stamping dies into position with 318 kgf of maximum theoretical force, utilizing the rigid U flat-end back cover to resist straight axial loads.
Halts advancing pallets on a packaging line using a short 20 mm stroke, triggering the CMSG reed switch to confirm the stop arm is fully deployed.
As the largest bore in the MBL series, the 63 mm size offers maximum thrust. If 1558 N at 0.5 MPa is excessive for your payload, step down to the 50 mm bore, which provides 981 N of push force. Because this is the top standard size, there is no larger MBL option. If your cycle speed is high and the fixed rubber bumper cannot absorb the kinetic energy, specify the MBLC variant for adjustable air cushioning.
This U flat-end model provides rigid rear mounting. Note that the plain MBL does not hold its load when air pressure is lost; the rod will drift or drop if the valve is centered or exhausted. Use an external pilot-operated check valve or rod lock if gravity or external forces require position holding. Replacement matches: 63 mm bore, 20 mm stroke, G1/4 port, PT thread, U flat-end back cover, and a built-in magnet.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder provides 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 MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. If your application requires adjustable air cushioning for heavier or faster moving loads, select the MBLC variant instead.
