The ta profile is a rotary shaft seal composed of a single external metal cage at outside with an internal rubber coating and this rubber coating is enveloped in the another metal casein this type root of the sealing lip is bonded to id of outside metal ring. Outer metal reinforced with inner metal to have structural rigiditya garter spring uniform load, Provides constant of the lip on the shaft for the spirit of the seal. The spring keeps the elastomer lip in touch with the shaft during higher shaft speeds and also helps offset normally occurring compression characteristics and wear of the lip material. The secondary lip provides exclusion of light dust and fluid contaminants. Advantages good radial rigidity particularly for large diameters. Sealing for high and low viscosity fluids modern primary sealing lip with low radial forces protection against undesirable air contaminants have greater strength then tb type standard seal material nbr temp, 20f /, 250f fkm temp, 40f /, 400f metal ring steel, Aisi 1010 stainless steel, Aisi 304 stainless steel, Aisi 316 spring steel, Aisi 1070, 1090 stainless steel, Aisi 316
