In high-temperature processing techniques such as baking, frying, and grilling, chains and bearings require the use of expensive high-temperature food grade bearing grease for supplementary lubrication. However, frequent lubrication can increase the cost of lubricants and maintenance, and in some cases, excessive grease can contaminate the product. Faced with the challenge of extreme high temperatures, DOS' graphite based lubrication free bearing technology can help the food machinery industry improve equipment performance and production line efficiency, ultimately reducing overall operating costs.
