Bushings

Introduction

Anti-friction rotary bushings are self contained bearing cartridges used to support and guide rotating cutting tools. They consist of a stationary outer case; a hardened and ground inner liner which rotates with the cutting tool; anti-friction bearings and seals. They are manufactured in several series with each having distinct advantages that cover the broadest range of metal working applications. While available in a wide range of standard sizes, Gatco Rotary Bushings are commonly and readily modified to suit individual requirements or specifications.
