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.

Diamond-Groove Bushings (DG) FAQ

Can DG bushings be pressed in?

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.

Quick-Ship sizes are the most popular Carr Lane drill bushings, kept in stock at the St. Louis warehouse and ready for same-day shipment. Other sizes in the same series are made to order with a longer lead time.

Can you quote ADB, Boneham or ACTEK equivalents?

Yes. Send the Carr Lane part number or your print and we will quote the matching ADB, Boneham or ACTEK bushing alongside the Carr Lane part, so you can compare price and lead time.
