The AirTAC AirTAC MBL63X200SCA Mini Cylinder | 63mm Bore 200mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 200mm 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 MBL63X200SCA is a genuine double-acting aluminum mini round cylinder built for heavy-duty work in tight machine envelopes. Delivering 1558 N of push force at 0.5 MPa over a 200 mm stroke, it relies on a riveted rolling-packed barrel that crimps the covers directly to the tube for maximum structural rigidity. Because this SKU includes the -S suffix, it arrives with a built-in magnet ready for CMSG, DMSG, or EMSG electronic sensor switches to track rod position.
This specific configuration uses a CA pivot back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads during operation. To survive high-impact cycles, the carbon steel piston rod is protected by a 20 µm hard-chrome plating, and the internal heterogeneous two-way piston seal continuously retains grease for extended mechanical life. The end-of-stroke deceleration is handled by a fixed rubber bumper, which absorbs shock without adding external bulk.

Swings a heavy diverter arm on a packaging line conveyor, utilizing the 1558 N push force to shift boxed goods into secondary lanes at high speed.
Actuates a sliding machine tool safety door, where the CA pivot bracket accommodates the slight arc of the hinge mechanism during the 200 mm travel.
Pushes finished plastic parts out of a small injection mold cavity, relying on the DMSG solid-state sensor to confirm full ejection before the mold closes.
Choosing the 63 mm bore makes sense when your application requires substantial thrust, pushing 1558 N at 0.5 MPa or peaking at 318 kgf at 1.0 MPa. If you need to step down to save space and air consumption, the neighboring 50 mm bore provides 981 N of push force at 0.5 MPa. Since this is the largest standard MBL bore size, stepping up further would require moving away from the mini round format entirely to an ISO 15552 profile cylinder like the AirTAC SAI series. For this 200 mm stroke, the CA pivot back cover is highly recommended over the fixed U flat-end, as the unsupported rod length benefits from the articulation to prevent side-load binding.
Because the base MBL uses a fixed rubber bumper instead of an adjustable air cushion, extremely fast or heavy loads might cause end-cap wear; in those cases, step up to the MBLC variant for tunable end-of-stroke deceleration. Remember that a plain pneumatic cylinder cannot hold a load in place if air pressure drops or the valve is centered—the rod will drift. If your mechanism requires fail-safe holding, you must add an external pilot-operated check valve or a dedicated rod lock. The exact replacement match for this SKU is: 63 mm bore, 200 mm stroke, G1/4 port, PT thread form, CA pivot back cover, and an -S magnet.
Quick checklist
This 63 mm bore cylinder delivers a push force of 1558 N and a pull force of 1457 N at 0.5 MPa. At 0.7 MPa, the push force increases to 2181 N, with a maximum theoretical force of 318 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
No, the base MBL features a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable cushion screw. If your 200 mm stroke is moving a heavy load at high velocity and requires tunable deceleration, you should select the MBLC variant, which offers adjustable air cushioning.
