80/20, Inc. 80 20 6424 Dbl Flange Long Linear Bearing With Brake Holes

80/20, Inc. 80 20 6424 Dbl Flange Long Linear Bearing With Brake Holes is a dual-flange linear bearing block intended for precise motion in 80/20 aluminum extrusion systems. The 6424 variant measures 3.93 inches long by 4 inches wide and 1.2 inches high, and it includes brake holes for attaching braking components or locking hardware as part of a controlled positioning setup. The double-flange configuration provides mounting stability on both sides, aiding alignment with the corresponding linear track and reducing side-to-side play during travel. This long-form bearing block is suitable for custom automation frames, workstations, and light-duty positioning or travel tasks where a compact footprint and braking capability are important. With its specific dimensions and part-number identity, it is a distinct option within the 80/20 catalog for projects requiring a two-flange block that accepts brake-related hardware along a linear path.
