The changes in the design and speed of paper machines in the last 15 years have had a dramatic impact on the design of wear surfaces in contact with the fabrics. On the majority of new machines, ceramic is now the prominent bearing surface for the fabrics.

Anyone who has had the responsibility of choosing ceramic for a paper machine application and has investigated the choices thoroughly will have experienced the confusion that exists in the marketplace.

The paper industry has many standards covering its products and its operations, but it has not established standards to cover the materials that support paper machine clothing.

Ceramic names such as aluminum oxide, zirconia, silicon nitride and silicon carbide are generic, and manufacturers formulate many versions in each family, making selection by name alone ineffective.

Johnson Foils has been supplying ceramic covers to the paper industry for over 20 years and pioneered the development of continuous slotted ceramic suction box covers. In the process of evaluating ceramics, we have produced the only testing methodology in the industry that predicts overall ceramic performance on the paper machine. This information has allowed our customers to make informed decisions when selecting the best ceramics for their applications. We can manufacture most shapes and materials in the field today, and we welcome the opportunity to make our recommendations for your application.
