A paint drying oven at a brake shoe manufacturer was experiencing two months life from their roller bearings after being exposed to temperatures of 390ºF (200ºC). In spite of the water cooling system in the rollers, the bearing lubrication was failing and causing roller seizure and extensive maintenance costs.
Self lubricating GRAPHALLOY® 845 Series Pillow Blocks were installed, eliminating the need for constant lubrication and the need for the water cooling systems. The 845 Pillow Blocks have run for more than a year with no apparent wear. GRAPHALLOY provided a significant improvement in the life of the bearings.
