This sintered steel hub allows teams to use their existing wheels and gears with the improved reliability of a 5mm hex shaft. The High Strength Hex Hub have a number of new features which work better with the existing REV product line as well as maintaining the ability to retrofit any of the "4-hole" mounting wheels you might already have from our friends at AndyMark or Tetrix.

This 8mm x 12mm x 3.5mm Flanged Bearing, when paired with the 5mm Hex to 8mm Round Bearing Insert (REV-41-1528), allows teams to support our 5mm hex shaft with a robust low friction bearing. We recommend mounting the bearing into the 12mm Bearing Mount (REV-41-1452). It can also be mounted into almost any REV bracket with a REV Motion pattern by using our Metric Step Drill (REV-49-1455) to widen the bore to 12mm.
