The AirTAC AirTAC MBL63X125SCA Mini Cylinder | 63mm Bore 125mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 125mm 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 MBL63X125SCA is a double-acting aluminum mini round cylinder engineered for heavy-duty compact automation. It delivers a robust 1558 N push and 1457 N pull force at 0.5 MPa, making this 125 mm stroke variant ideal for moving substantial loads within confined machinery. As the largest bore in the MBL series, it pairs a G1/4 port with a Ø16 mm carbon steel rod to handle high flow and thrust demands.
This SKU includes a built-in magnet (-S) for rod position detection using CMSG reed or DMSG/EMSG electronic switches. Unlike tie-rod bodies, the MBL features a riveted rolling-packed barrel where the covers are crimped to the tube, creating an exceptionally light yet permanently sealed assembly. The CA pivot back cover allows the cylinder to swing on a pin, absorbing angular misalignment during arcing motions. End-of-stroke energy is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Leveraging 1558 N of thrust at 0.5 MPa, this cylinder pushes heavy pallets onto auxiliary transfer lines where workspace clearance is strictly limited.
The 125 mm stroke knocks finished metal blanks out of progressive dies, utilizing the CA pivot to tolerate slight angular offsets during rapid ejection.
A robust 318 kgf maximum theoretical force drives loaded cardboard cartons from sorting belts into packing chutes, with the -S magnet confirming full extension.
Selecting this 63 mm bore provides the maximum thrust available in the MBL mini series. If your application requires less force, stepping down to the 50 mm bore yields 981 N push at 0.5 MPa, while this 63 mm unit is the top tier offering 1558 N. For repetitive heavy payloads needing deceleration control, consider the MBLC variant which replaces the fixed rubber bumper with an adjustable air cushion. To match this exact SKU for replacement, specify: 63 mm bore, 125 mm stroke, G1/4 port, PT thread, CA pivot back cover, and the -S magnet. Note that the standard MBL cannot hold a load if air pressure is lost; the rubber bumper softens impact but does not function as a braking rod lock.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder outputs 1558 N push and 1457 N pull. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa operating pressure.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact and cannot be adjusted. If your application requires adjustable end-of-stroke deceleration for heavier moving masses, you should select the MBLC variant.
