Their powder coating department uses overhead tracks and trolleys to suspend products weighing up to 10,000 kg (22,250 lbs). The items are moved manually in and out of a 200° C (390° F) curing oven. The Sogelub® Stabigrease they were using could not stand up to the heat and was bleeding out of the bearings. Removal and greasing of the trolley assemblies was labor intensive and they were still losing 100 bearings per year. Poor lubrication also made it very difficult to push products along the tracks. Besides the costs for expensive greases, wages and production outburst, bearings were replaced on average yearly.
