Installation
Shaft
- tolerance ISO h11;
- surface finish roughness Ra 0.2 to 0.8 [μm];
- hardness of the shaft surface 55 HRC or more.
Housing
- bore tolerance ISO H8;
- surface finish roughness Ra 1.6 to 6.3 [μm].
D5P
This seal is designed for use in presence of pressure, up to max 0.6 [MPa]. The radial force on the shaft caused by the pressurized fluid is reduced and, as a consequence, there is a reduction of temperature. The absence of external metal avoids the possibility to damage the seal housing. This type of seal needs a retaining flange.
D7
With annular groove in addition to ports, allowing lubricant to pass around to the sealing lips. Usually twin fitted back to back.
