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. Pumping leads Clockwise Anti-clockwise Bi-directional R L H0 Other types of pumping leads can be created according to your specifications. Please contact our experts. |DESCRIPTION The TCHP profile is a high-pressure shaft seal composed of a single metal cage with a rubber coating, primary sealing lip with an integrated spring and an additional anti-pollution lip. |ADVANTAGES Very good static sealing Very good thermal expansion compensation Greater roughness is allowed in the housing Reduced risk of corrosion Sealing for low and high viscosity fluids Primary sealing lip designed for higher pressures up to 1 MPa Protection against undesirable air contaminants |APPLICATIONS All types of rotative applications 2-stroke engines Hydrostatic commands (motors and pumps) |MATERIALS Rubber FKM 75 - 80 - 85 - 90 Shore A HNBR 75 - 80 - 85 - 90 Shore A NBR 75 - 80 - 85 - 90 Shore A Metal cage Steel - AISI 1010 Spring Steel - AISI 1070 - 1090 HIGH-PRESSURE SHAFT SEALS TCHP QUALITY & EXPERTISE FOR YOUR SEALING NEEDS ROTARY SEALS | HIGH-PRESSURE SHAFT SEALS | TCHP
