SF-2SB

SF-2SB is a high performance material, with a very high friction coefficient, containing a high percentage of aramid fibers and steel shavings. It’s considered as an alternative for sintered materials, and it offers many advantages in front of them. It resists high energy inputs and is perfectly suitable for both dry and oil-immersed applications. It’s not abrasive against the mating material at all, actually so smooth and friendly against it, and it resists very high surface pressures. The wear rate is so low even at high temperatures. SF-2SB is available from 0.5 [mm] thicknesses
