The AirTAC AirTAC MBL63X175SCA Mini Cylinder | 63mm Bore 175mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 175mm 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 MBL63X175SCA is a double-acting aluminum mini round cylinder engineered for tight machine spaces where high force is still required. At its core, a 63mm bore generates 1558N of push force at 0.5MPa, extending a 175mm stroke via a carbon-steel rod with 20μm hard-chrome plating for superior wear resistance. This specific SKU includes the CA pivot back cover, allowing the cylinder body to swing on a pin to safely absorb arcing and angular loads during motion. The riveted rolling-packed barrel keeps the overall footprint exceptionally light and compact.
Because this model carries the -S suffix, it features a built-in magnet for position sensing. You can mount AirTAC CMSG reed switches or DMSG and EMSG solid-state sensors directly to the body for precise end-of-stroke detection. Unlike larger profile cylinders, this unit relies on a fixed rubber bumper at the end caps to soften impact rather than an adjustable air cushion. For heavy loads needing deceleration tuning, the MBLC variant is the recommended upgrade.

Swings on a CA pivot pin to extract heavy molded parts from injection molding machines, utilizing the 1558N push force to reliably clear the mold area.
Drives heavy angular diverting arms on packaging conveyor lines where the 175mm stroke and CA clevis allow the mechanism to pivot packages smoothly.
Uses the -S magnet with DMSG solid-state sensors to confirm full extension when pushing heavy printed circuit board stacks into testing fixtures.
Selecting this 63mm bore makes sense when your application demands substantial thrust, specifically 1558N push and 1457N pull at 0.5MPa. If you need less force and a smaller footprint, stepping down to the 50mm bore yields 981N push. If you require even more power, 63mm is the largest standard MBL size available. The 175mm stroke provides ample travel, but at this length the Ø16mm rod has lower side-load tolerance. The CA pivot back cover on this SKU is ideal for mitigating these bending stresses by allowing the cylinder to articulate. Alternatively, an external guide or the MBLD double-rod type can provide rigid anti-rotation support.
Remember that the fixed rubber bumper only softens end-of-stroke impact; it does not lock the rod. If air pressure drops, the load will drift. For position holding without live pressure, integrate an external rod lock or a pilot-operated check valve. This SKU uses a G1/4 port with a default PT thread form, an M14x1.5 rod-end thread, and accepts LB, FA, or SDB mounting accessories.
Quick checklist
At 0.5 MPa it provides 1558N push and 1457N pull. At 0.7 MPa the push force reaches 2181N. The maximum theoretical force is 318 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
No, the base MBL features a fixed rubber bumper that cannot be adjusted. If your application requires adjustable end-of-stroke deceleration for heavier moving masses, you should select the MBLC variant, which offers adjustable air cushioning.
