Oil seal OS-C12
OS-C12
Description
- Metal OD + reinforcement cap
- Non-spring-loaded sealing lip
Special features
- Non-spring-loaded lip design for secondary sealing jobs e.g., grease sealing
- Low friction
- Compact design
- Little installation space
- Firm and exact fi t inside the housing
- Be careful when using the product in connection with light metal housings, housings with increased surface roughness and applications with overpressure: Apply sealing aid to the outside diameter if necessary. A version with outside diameter coated with bore sealant is available on request.
Applications e.g.:
- Secondary sealing jobs
- Mechanical and apparatus engineering
- Drive systems
- Electric motors
