Oil seal OS-W11
OS-W11
Description
- Pressure loadable radial shaft seal
- Metal OD
- Spring-loaded elastomer sealing lip
- Protective lip against entry of contamination from outside (dust, dirt,...)
- Sealing lip and protective lip are clamped between the metal cases
Special features
- Pressure loadable
- Non-moulded processing
- Inside diameter from 45mm / outside diameter from 65mm to 1220mm possible
- No extra cost for special sizes or special tolerances
- Small runs without mould cost possible
- Short delivery time
- Very firm and exact fit inside the housing due to metal-metal interference fit
- 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.
- Efficient protection against air side contaminations
Applications e.g.:
- Heavy engineering
- General mechanical engineering
Materials
Standard material
| Sealing lip | NBR |
| Metal case | Carbon steel |
| Spring | Carbon spring steel |
Special materials
| Sealing lip | FKM, Silicon, EPDM |
| Metal case | Stainless steel AISI 316L |
| Spring | Stainless steel AISI 316L |
Application parameters
For the standard materials combination
| Temperature | -40°C to +100°C |
| Pressure | max. 0,05 MPa (optional 1 MPa) |
| Shaft speed | max. 8 m/s |
| Media | Mineral oil based lubricants, synthetic lubricants |
When synthetic lubricants are used for which there is no empirical experience, test the compatibility in the laboratory or - better even - in practical trials. The operating temperature should not exceed 80°C.
The diff erent permitted maximum values should always be seen in connection with all application parameters. The total load on the seal is the combination of individual values.
