When McDONALD’s wanted to roll over their signs after breakfast the sign manufacturers called on our Spyraflo colleagues in America to help provide a quality, durable solution. Every morning, whatever the weather, in thousands of McDonald's restaurants throughout the world the menu changes from an early start breakfast selection to the daytime delicacies.

The menu-boards need to change not only silently, but effortlessly and thanks to the design partnership between the Golden Arches Company, Florida Plastics International and bearings from Spyraflo, the answer was found.

Florida Plastics International is a key partner with McDonalds supplying innovative power driven menu boards and signage for all their fast food outlets. The design criteria for the revolving menu boards were reliability, maintenance free and silent. The challenge faced by the designers was to incorporate display material, lighting and a power transmission system into a large sheet steel frame. It had to be designed taking weight and size into consideration, ease of use and with economy in mind.

The final design required bearings able to accommodate chassis manufacturing tolerances as well as misalignment caused during shipping and installation of the finished assembly. To achieve this the Spyraflo BFM-375-A, flange-mount, self-aligning, Delryn®, 10mm diameter bearings were selected. The combination of ±5º self-alignment and the zero maintenance Delryn® bearing gives smooth rotation with minimum start-up torque.

This collaboration has resulted in a successful display that informs and keeps customers satisfied.
