Standard sealing element according to i.e. the DIN 3760, for the sealing of rotating shafts against pressureless chambers or chambers with a low pressure difference. The application range covers the whole engineering range. A sealant not only for sealing shafts against oils, fats and other mediums, but also preventing dust and dirt from entering through the sealing point.
Oil Seal Type RR
The Radial Oil Seal Type RR is designed as a pressure resistant rotary sealing. This has a metal outer diameter for an increased press fit in the bore und an additional clampling ring for the PTFE gasket. It can be utilized for low viscosity media and gas applications if the surface treatment is machined accordingly.
It is particularly suitable for rotating shafts in housings with applications which either have no pressure or have a pressure differential up to 2,5 MPa. High circumferential speeds and stick-slip free running is possible also with deficient lubrication due to the PTFE seal lip.
The PTFE seal lip and the metal casing provide a very good chemical resistance.
