Radial shaft seal with low cross-sectional height for needle roller bearings, G design
Radial shaft seals with low cross-sectional height are intended for bearing arrangements that incorporate needle roller bearings.
These contact seals are designed without garter springs. G design seals are made of rubber, with a single lip. Seals for shaft diameters ≥ 8 mm are reinforced with sheet steel. The rubber outside diameter enhances the seal around the housing bore and reduces the risk of damage to the seal and housing during installation and removal.
- Low cross-sectional height
- Retain the lubricant
- Exclude contaminants
