Main features:
- stable sealing lip
- good oil resistance
- reliable industrial durability
Typical applications:
- industrial machinery
- automotive systems
- drive assemblies
SEO phrases:
- B1 oil seal
- B1 shaft seal
- industrial B1 seal
AO - oil seal without spring
What does AO mean?
AO refers to a shaft seal without a garter spring.
Typical applications:
- low-speed systems
- light-duty machinery
- simple mechanical assemblies
This type is not intended for highly demanding operating conditions.
How to choose the correct oil seal type?
Selection depends on:
- operating temperature
- contamination level
- working media
- shaft rotational speed
- operating pressure
- environmental conditions
Most common Corteco seal materials

Most common mistakes when selecting oil seal types
Ignoring operating conditions
Many users select shaft seals only by dimensions.
This is a major mistake.
Seal construction, material, and operating environment are equally important.
Using the wrong seal type in dusty environments
Example:
- using BA instead of BASL in contaminated conditions
This may lead to:
- accelerated wear
- contamination ingress
- shaft and bearing damage
