The TO profile is a double-lip shaft seal consisting of a single metal case with a rubber coating, a primary sealing lip with an integrated spring, and a dust lip that acts as a barrier against external dirt buildup. The rubber coating is applied through injection molding.<\/p>\n
CHARACTERISTICS <\/span><\/h6>\n
\n
Good static sealing.<\/li>\n
Compensation of different thermal expansion.<\/li>\n
Reduced risk of fretting corrosion.<\/li>\n
A higher surface roughness of the bore is allowed.<\/li>\n
Sealing for low- and high-viscosity fluids<\/li>\n
Modern primary sealing lip with low radial forces<\/li>\n
Protecci\u00f3n contra contaminantes no deseadas del aire.<\/li>\n
Rubber coating applied by injection molding<\/li>\n<\/ul>\n

When not under pressure, the inside diameter of the sealing lip is always smaller than the shaft diameter. The difference between the two dimensions is known as interference or pre-fitting. Depending on the shaft size, the sealing lip diameter is estimated to be between 0.8 mm and 3.5 mm smaller. It will depend on the setting chosen by each manufacturer.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
