FEATURES: This bush can be cast in place or potted, just like a Diamond-Groove Bush, or can be pressed into an installation hole. The straight knurl provides excellent resistance to rotation, but provides less resistance to axial forces than a diamond knurl. Since the bush's OD is not ground, the ID must be accurately located during casting or potting to ensure accuracy in the finished tool.
