Ductile Iron Yoke Bearing Housing

(click on thumbnail to enlarge)

At RB Tool & Manufacturing Company, we deliver fully finished parts, providing you with a single source that you can count on for high quality machined components. Our precision machining services can accommodate most materials, with superior expertise in machining ductile iron. The yoke bearing housing shown here was manufactured for a customer in the packaging machinery industry, and its production took advantage of the many services we have to offer.

Used in a bottle capping machine, this bearing housing was milled from 60-40-18 ductile iron, which we annealed to improve its machinability before fabricating this close tolerance part. We employed our modern milling equipment to form the part. The flats and diameters, were then ground to the extremely tight tolerances of +0.0005"/-0.0000". Overall finished dimensions were 15.88" in length, and 3.752" in height. Application of a black oxide finish maximized corrosion resistance, and light assembly operations consisted of installing the fitting.

Each step in this multi-process manufacturing cycle involved visual and dimensional inspections in accordance with our ISO 9001:2008 quality management system. We built this component, from start to finish, with the precision, hardness, and wear resistance needed to provide a long service life under the stresses of a high speed packaging operation. If you would like to learn more about how our broad range of services can simplify your sourcing requirements, contact us today.
