SF-BU

SF-BU is a high performance metal free material, with a standard friction coefficient. It has a high percentage of aramid fibre. It can be considered as an alternative for sintered metal materials and offers many advantages. It resists high energy inputs and is suitable for both dry and oil-immersed applications. It is not abrasive to the counter material, and it's noiseless while operating. It resists high surface pressures. The wear rate is low even at high temperatures. SF-BU is available in thicknesses from 0.4mm to 7.5mm.
