Usage examples

Installation relations

The contact surface of the seal needs to be hardened and ground to obtain good sealing performance. In addition, there should be no harmful scratches or indentations on the contact surface of the seal. When the raceway surface of the inner ring is used as the seal contact surface, a wide inner ring is used.
It is desirable to provide a tapered surface on the shaft flange or housing flange so as not to damage the lip and outer diameter surface when installing the seal (Fig. 1). If there is no tapered surface or roundness at the shaft end, it is advisable to use a mounting jig as shown in Fig. 2. As for the tightness between the seal and the housing, a sufficient tightness can be obtained within the range of the normal housing tolerance G7 to R7.
To lubricate the G-shaped lip seal, it is advisable to apply a lubricant to the lip part at the time of installation. Be careful not to turn over the lip when installing the seal or shaft.
