The pre-tightening or interference denotes the difference between these two values. Depending on the shaft diameter, the diameter of the sealing lip is generally considered to be less, between 0.8 and 3.5 mm. |DESCRIPTION The KB2 profile is a shaft seal composed of a single external metal cage, a primary sealing lip without a spring and an additional anti-pollution lip. |ADVANTAGES Good radial rigidity, particularly for large diameters Good stability when assembled, preventing the bounce-back effect Sealing for high viscosity fluids Primary sealing lip generating low levels of friction and heat Protection against undesirable air contaminants |APPLICATIONS All types of rotative applications Machine tools Agriculture Construction Transmission Gear boxes Motors Pumps |MATERIALS Rubber ACM 70 - 75 Shore A EPDM 70 - 75 Shore A FKM 70 - 75 Shore A HNBR 70 - 75 Shore A NBR 70 - 75 Shore A Metal cage Steel - AISI 1010 Stainless steel - AISI 304 Stainless steel - AISI 316 STANDARD SHAFT SEALS KB2 ROTARY SEALS | STANDARD SHAFT SEALS | KB2 QUALITY & EXPERTISE FOR YOUR SEALING NEEDS
