The pre-tightening or interference denotes the difference between these two values. Depending on the rod diameter, the diameter of the sealing lip is generally considered to be less, between 0.8 and 3.5 mm. |DESCRIPTION The TCW4 profile is a shaft seal composed of a single metal cage with rubber grooves on the outside of the cage and a double sealing lip with integrated spring, suitable for linear movements. |ADVANTAGES Very good static sealing Very good thermal expansion compensation Greater roughness is allowed in the housing Reduced risk of corrosion Easy to assemble with very limited bounce-back effect Sealing for low and high viscosity fluids Modern primary sealing lip with low radial forces Protection against undesirable air contaminants Sealing lips designed for linear movements |APPLICATIONS All types of linear applications Shock absorbers Steering |MATERIALS Rubber FKM 75 - 80 Shore A HNBR 75 - 80 Shore A NBR 75 - 80 Shore A Metal cage Steel - AISI 1010 Steel - DC01 C490 Steel - DC01 C590 Spring Steel - AISI 1070 - 1090 Stainless steel - AISI 316 SEALS FOR LINEAR MOVEMENTS TCW4 ROTARY SEALS | SEALS FOR LINEAR MOVEMENT | TCW4
