TT137 Pressure-Driven Bronze Sintered Mat’l

Home » Sintered » TT137 Pressure-Driven Bronze Sintered Mat’l
TT137 is a pressure-driven sintered bronze/iron friction material. The relatively high proportion of bronze, as well as the carefully chosen types of graphite and silicate result in an extremely high wear resistance, even under high energy conditions. TT137 offers a mid-high friction coefficient with smooth engagement while preserving the mating surfaces. The material is free of lead.
