Tufnol SRBF Material - Bear Brand Brand
Cotton fabric based laminate
Medium weave cotton/phenolic resin laminated plastic
(SRBF – Synthetic Resin Bonded Fabric)
Bear Brand Tufnol is a cotton fabric grade specially formulated for use as a lubricated bearing material. It has enhanced wearing properties and dimensional stability and gives excellent performance in a multitude of bearing applications, using water as a lubricant, or more conventional oils or greases. The low water absorption properties allow reduced clearances in bearings and also provide enhanced electrical insulation properties.
What is Bear Brand used for?
Bear Brand is used for a wide range of wearing and bearing applications, such as oil or grease lubricated bearings, slideways, water lubricated marine bearings, pump sleeve bearings, seal rings, mixer bearings, slipper pads, rolling mill bearings, guide bushes and a wide variety of components which are lubricated by the water-based process fluids in which they operate.
