Single Lip with Flinger (Flinger
Seal)
 |
UK: Single Lip with Flinger
|
As shown in the example (see illustration UK), a
single lip molded rubber seal is bonded to a steel backing plate.
The rubber seals snap into grooves in the bearing’s outer ring.
The seal lip rides on the inner ring outside diameter which has
been ground to provide a smooth contacting surface. The additional
metal flinger protects the seal lip and is pressed onto the inner
ring’s outside diameter.
NTN’s flinger has triangular protrusions on its outside face
and, as the bearing rotates, these protrusions create a flow of
air outward from the bearing. In this way, the flinger acts as a
fan which keeps dust and water away from the bearing. This design,
in combination with the seal, is very effective in highly contaminated
applications. The protrusions on the flinger repel contaminants
such as dirt, straw, sand and water. The flinger also provides excellent
protection against crop wrap damage. The seal is used on UC, UEL,
and SBX (special dimension) series insert bearings.
