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 SCJ profile is a shaft seal composed of a single metal cage with a rubber coating and a single sealing lip with a PTFE coating and integrated spring. |ADVANTAGES Very good static sealing Very good thermal expansion compensation Greater roughness is allowed in the housing Reduced risk of corrosion Waterproofing for low and high viscosity fluids, and for environments with little lubrication Modern primary sealing lip with low radial forces Bonded PTFE tape for a low friction coefficient that tolerates greater speeds |APPLICATIONS All types of rotative applications Machine tools Agriculture Construction Transmissions Automotive Military |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 Lip adhesion PTFE Metal cage Steel - AISI 1010 Spring Steel - AISI 1070 - 1090 Stainless steel - AISI 316 SHAFT SEALS WITH PTFE COATING SCJ ROTARY SEALS | SHAFT SEALS WITH A PTFE COATING | SCJ
