Seal G Type

Seal G Type

Seal specially designed for use with needle roller bearings with a small cross-section height.

[Features]
· Seal specially designed for use with needle roller bearings with a small cross-section height.
· Contact seal made of synthetic rubber reinforced by steel plate, with an operating temperature range of -25° to 120°C, and 100°C or less for continuous use.
· A G model with a single lip and a GD model with two lips are available.
· Hardening and finishing by grinding of the contact surface of the seal is necessary in order to obtain good sealing performance.
· In addition, there should not be any harmful damage or indentations on the contact surface of the seal.
· The inner ring raceway surface should preferably be used as a seal contact surface.
· A suitable press-fit between the seal and the housing can be obtained within a normal housing tolerance of G7 tp R7.

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.

Product features details

It is a dedicated seal specially designed for the small cross-sectional height of needle-shaped roller bearings, and has the function of preventing contaminant from entering and holding grease.

  • There is a G type with 1 lip and a GD type with 2 lips.
  • It is composed of a steel ring and synthetic rubber, and the operating temperature range is -25 to 120°C, and 100°C or less for continuous use.
  • Since the shell type needle roller bearing and the radial cross-sectional height match, no alteration of the housing is required, so it is easy to handle.
