BBHM Industrial Brake Roll Lining

Material Description: BBHM is a semi-flexible asbestos-free brake lining, manufactured from viscose fiber, glass fiber with a brass wire inclusion, which helps to stabilise the friction value by conducting heat from the operating surface.
When the woven fabric is impregnated with the specially developed synthetic resin it produces a friction material with excellent stability and high resistance to wear.
This material can be supplied for use on oil immersed applications, although the friction value will be much lower than shown on the wear performance table below which is based on dry conditions.
A most efficient general purpose brake lining suitable for use on mostapplications, including winches, cranes, earthmoving and agricultural equipment, forging machinery and many others.
