Warburtons wanted to increase the efficiency of the ovens at its Enfield site, where oven unloaders transport trays of product on rollers throughout the day. The efficient daily repetition of this process depends on resilient bearings that can cope with temperatures of up to 120C. The need to re-lubricate with expensive high-temperature greases places a heavy burden on maintenance and costs.
SKF bearings are fitted with a graphite cage that releases minute amounts of graphite powder to lubricate the bearing, which offers a dry option for high-temperature, low-speed uses, such as ovens.
The reduced costs of work comes to almost £7,000 a year, while the total benefits of MTBF against costs are expected to deliver a return on investment of 200%.
