Oil Seals

SC

Single lip, rubber covered, spring-loaded.Can accommodate considerable surface roughness and thermal expansion of the housing and will not rust.
Required for split housing and when sealing gaseous or low viscosity media.

SB

Single lip, Bare in outer metal case, spring loaded.
Sealing is more difficult with housing bore of considerable surface roughness andsubject to thermal expansion.

SA

Single lip, outer metal case with reinforcing case. Spring loaded.
Installation and sealing identical to Type SB, it is preferred for larger size application.

TC

Twin lips, rubber covered, spring loaded.
An Extra lip is required to exclude foreign matter from the primary sealing lip.

TB

Twin lips, Bare in outer metal case, spring loaded.
Can be used in applications requiring the extra lip for foreign matter exclusion but where the extra strength of an inner case is not needed.

TA

Twin lips, outer metal case with reinforcing case, Spring loaded.
It is recommended where an extra lip is requested to excluded foreign matter from the primary sealing lip.
The inner case provided for maximum strength, rigidity and protection of sealing lip and spring.

VB

Single lip, outer metal case, springless.
Sealing identical to Type VC, metal housing for particularly firm and exact seating in the bore.

VA

Single lip, outer metal case with reinforcing case, springless.
Sealing identical to Type VB, with inner case provided for maximum strength, rigidity and protection of sealing lip.

KC

Twin lips, rubber covered, springless.
Sealing identical to Type VC, with an Extra lip is required to exclude foreign matter from auxiliary sealing lip.

KB

Twin lips, outer metal case, springless.
Sealing identical to Type KC, metal housing for particularly firm and exact seating in the bore.

KA

Twin lips, outer metal case with reinforcing case, springless.
Sealing identical to type KB, with inner case provided for maximum strength, rigidity and protection of sealing lip.

DC

Rubber covered outer, incorporated Two spring-loaded lips for sealing of two medias.

DB

are in outer metal case, incorporated Two spring-loaded lips for sealing of two medias.

DA

Bare in outer metal case with reinforcing case, incorporated Two spring-loaded lips for sealing of two medias.

VC

Single lip, rubber covered, springless.
It is recommended somewhere against grease, secondary application against moderate to medium dust and dirty ingress.
