The OD of a DG bushing is not ground, so locate the ID accurately during casting or potting. Reamer ID tolerance (+.0006/+.0010) is available by adding -REAMER to the part number. For a straight-knurl alternative, see Serrata-Groove (SG) bushings.

DG bushings are designed for cast-in-place or potted installation. If you need a castable bushing that can also be pressed in, look at serrata-groove (SG) bushings.
