GRAPHALLOY® Keeps Dryer Oven Chains Rolling

Keeping their gypsum board dryer oven running was a problem for a manufacturer of construction materials until they redesigned the chain guide to include self-lubricating GRAPHALLOY^® cam followers.

The oven has a drag chain conveying system - with a speed of eight feet per minute - to move the gypsum wall boards through the oven. The temperature in the oven is 550°F. The drag chain was kept on track by chain guides made of carbon steel plates. Over time, the chain guides would wear down, fall onto the gypsum wall boards, destroy the product and shut down the oven. 

The manufacturer wanted to design a chain guide system that would not wear down and certainly not fall into the product. They needed something to support the chain. The manufacturer considered using standard cam followers but was concerned that they wouldn’t survive the oven’s high temperature. In addition, they wanted to avoid using grease to minimize frequent maintenance.

They contacted engineers at Graphite Metallizing Corporation to help with the new design. Self-lubricating GRAPHALLOY Bronze Grade Cam Followers Type 1217 were proposed. The manufacturer then developed a chain guide system that had the chains roll over the cam followers instead of the steel plates.

After testing this solution for ten months, the board manufacturer declared it a success. They converted their entire oven to GRAPHALLOY. These cam followers have now been in operation for over one year without the need for replacement. The manufacturer also saved time and money on reduced maintenance because they no longer need to grease their bearings.

Self-Lubricating Metric Cam Followers for Extreme Environments

Graphite Metallizing Corporation announces GRAPHALLOY® self-lubricating metric dimension cam followers. These metric cam followers are available in a variety of sizes suitable for a wide range of applications.

GRAPHALLOY metric cam followers do not contain oil or grease to harden, burn up, contaminate or wash away. These metric cam followers are now being offered in addition to stock cam followers which are made to industry standard dimensions. They are designed to handle moderate loads and speeds of up to 100 RPM. They provide reliable performance in temperatures up to 750°F (400°C).

Typical applications include bakery and industrial ovens, steel mill processing lines, glass plants, conveyors, kilns and stokers. GRAPHALLOY cam followers also perform in low temperature environments of -100° F (-75°C ) and in wet or submerged applications. Click here to read more about GRAPHALLOY metric cam followers.

GRAPHALLOY® Stainless Steel Cam Followers for Wet or Submersible Applications

Graphite Metallizing Corporation announces the availability of GRAPHALLOY® stainless steel cam followers for wet or submersible applications. These stainless steel cam followers are corrosion resistant and survive wash down and steam, eliminating the problems experienced with traditional cam followers.

GRAPHALLOY® cam followers do not contain oil or grease to harden, burn up, contaminate or wash away. They are designed to handle moderate loads and speeds of up to 100 RPM and provide reliable performance in temperatures up to 750° F (400° C).

Typical applications include bakery and industrial ovens, steel mill equipment, glass plants, conveyors, kilns, stokers and substrate dryers. GRAPHALLOY® cam followers also perform well in low temperature environments of -100° F (-75° C).

GRAPHALLOY®, a graphite/metal alloy, is a uniform, solid, self-lubricating material. GRAPHALLOY® cam followers will not deform under load, maintain dimensional stability and provide a constant low coefficient of friction for improved wear. GRAPHALLOY® cam followers are especially suitable in applications where lubrication or maintenance tasks are cumbersome, difficult or impossible to perform.

Graphite Metallizing's GRAPHALLOY® cam followers are made to industry-standard dimensions. Metric sizes and special or custom designs are also available.

GRAPHALLOY® Eliminates the Need for Grease and Keeps the Ovens Running

Glass ceramic is ideal for use in a variety of appliances because it is resistant to temperature extremes. This unique material is well-suited for use in cooktops and doors for microwave ovens and fireplaces.

Constant greasing and frequent failures drove a major manufacturer of glass ceramic to seek a better solution. The manufacturer was experiencing problems with their production ovens and dryers. Stud-type cam followers with grease lubrication were being used. The cam followers needed replacement after six months because the grease was failing at the high temperature (428° F/220° C).

After learning about the run dry, self-lubricating properties of GRAPHALLOY®  bearings, the manufacturer contacted Graphite Metallizing Corporation and requested a design solution. Eight standard GRAPHALLOY metric cam followers were installed for testing.

After five months, this manufacturer had already realized significant savings because of reduced maintenance costs and the elimination of high cost, high temperature grease. They were so pleased with the performance of the GRAPHALLOY cam followers that they ordered an additional 200 to retrofit their current ovens.

These GRAPHALLOY cam followers have now been in operation for over one year without the need for replacement or the constant greasing of the original equipment.

The manufacturer plans to retrofit additional ovens in plants worldwide with GRAPHALLOY cam followers.

GRAPHALLOY® Cam Followers For High Temperature Applications

Graphite Metallizing Corporation announces GRAPHALLOY® high temperature cam followers which outperform ordinary grease or oil-lubricated cam followers in high temperature applications.
