The AirTAC AirTAC MBL63X20SCA 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 MBL63X20SCA is a double-acting aluminum mini round cylinder engineered to deliver substantial thrust in compact machinery. It provides 1558 N of push force and 1457 N of pull force at 0.5 MPa. The 20 mm stroke is ideal for short, powerful clamping or ejecting motions. As a non-ISO specialty cylinder, its riveted rolling-packed barrel crimps the front and rear covers directly to the tube, creating a lightweight body that fits tight spaces where larger profile cylinders cannot.
This SKU includes a built-in magnet (-S) for rod position detection via CMSG reed or DMSG and EMSG solid-state switches. The CA pivot back cover allows the cylinder to swing on a pin, accommodating arcing or angular loads. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion. The carbon-steel piston rod features 20 um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life.

Provides the 1558 N push force required to knock out dense plastic parts from injection molds within a confined press envelope.
Uses the CA pivot mount to swing a heavy diverter arm on a packaging line, absorbing angular side loads during high-speed pallet routing.
Executes short 20 mm clamping strokes to hold sheet metal firmly in place during bending operations, using the -S magnet to confirm pinch closure.
As the largest bore in the MBL series, the 63 mm size offers maximum thrust. If you need less force to save space, step down to the 50 mm bore, which yields 981 N push at 0.5 MPa. Because this is the top size, there is no larger MBL option; for even higher force, consider migrating to an ISO 15552 profile cylinder like the AirTAC SAI series. The fixed rubber bumper suits standard cycling, but if your application involves heavy moving masses at higher speeds, upgrade to the MBLC variant for adjustable air cushioning.
A plain MBL does not hold its position or load when air pressure is lost or the valve is centered; the rod will drift. The rubber bumper only softens end-of-stroke impact and is not a lock. If load holding is required without live pressure, install an external rod lock or a pilot-operated check valve. For replacement, match the 63 mm bore, 20 mm stroke, G1/4 port, PT thread, CA pivot back cover, and -S magnet.
Quick checklist
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften the end-of-stroke impact, which cannot be adjusted. If your application requires adjustable air cushioning to handle heavier moving loads, you should select the MBLC variant instead.
