Heat and chemical resistant (non-corroding metal), electrical conductivity, abrasion resistance and improved sliding contact.
Thermal shock resistance. Withstand temperatures as high as 2000° C, this prevents softening or melting down of the carbon brush. Manufactured with Cold Isostatic Pressing (CIP) of micro particles to encapsulate an isotropic graphite
A low coefficient of friction and self-lubrication properties also viable under electrical conduction. Specifications: Material: Toyo Tanso carbon
Heat Resistance: 2000° C. Compatible with Bosch: 11250VSR / 11253VSR / 11255VSR / 1199VSR / 11250VSRD / 1199VSRK / HD21-2 / HD19-2 / RH328VCQ / SDS-PLUS , GBH 328 DFR / GBH 223 E / GBH 228 D / GBH 228 / GBH 228 DFV / HD 192 L / HD 192D / GBH 222 RE / GSB 182 RE / GBH 226 DRE / RH226 / GBH 228 F / GBH 328 DRE / GBH228 L / GBH 224 DRE / GBH 226 DDF / 36111BA3030 / 3611BA3060 / 3611BA3070 / 3611BA3090 / GBH 226 F / 3611BA4030 / 3611BA4060 / 3611BA4070 / 3611BA4090 / GBH 3000 / GBH 428 DFR The Superior Electric S71 carbon brush uses Toyo Tanso carbon, offering improved stability and reliability due to a low coefficient of thermal expansion (Compatible with Bosch models). This provides better thermal shock resistance giving the product properties such as heat and chemical resistant / non-corroding metal, electrical conductivity, abrasion resistance and improved sliding contact. Toyo Tanso preserves its stability with temperatures as high as 2000° C by doing so, this prevents softening or melting down of the carbon brush itself. Manufactured with Cold Isostatic Pressing (CIP) of micro particles to encapsulate an isotropic graphite. Abrasion Resistance due to a layered crystalline structure which ultimately means it has a low coefficient of friction and self-lubrication properties also viable under electrical conduction.
