Oil seal OS-Q13
OS-Q13
Description
- Fabric-reinforced OD
- Spring-loaded elastomer sealing lip
- Radial and annual lubricating grooves at the bottom side
- Relubrication is possible if 2 seals are installed back-to-back
Special features
- Modern sealing lip design for high dynamic sealing action
- Robust, fabric-reinforced outer diameter (no metal case)
- High resistance to wear
- For housings with increased surface roughness
- Simple installation and replacement of the seal possible
- All components of the seal are corrosion-resistant
- Split design available, can be replaced without deinstallation of the shaft
- Relubrication possible due to radial and annular grooves
Applications e.g.:
- Heavy machinery
- Marine applications
- Rolling mills
- Wind power systems
- Large gearboxes
Materials
Standard material
| Sealing lip | NBR 80 |
| OD layer | NBR-impregnated cotton fabric |
| Spring | Stainless steel 1.4310 |
Special materials
| Sealing lip | FKM 80 |
| OD layer | FKM- impregnated cotton fabric |
| Spring | Stainless steel 1.4310 |
Application parameters
For the standard materials combination
| Temperature | -30°C to +100°C |
| Pressure | Drukloos, max. 0,05 MPa |
| Shaft speed | max. 20 m/s |
| Media | Mineral oil based lubricants |
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.
Design information
Shaft
| Tolerance | ISO h9 |
| Hardness | 60 HRC |
| Roughness | Ra = 0,2 - 0,8 μm |
| Rmax | ≤ 2,5 μm |
| Surface finish | free of orientation (lead free) |
Housing bore
| Tolerance | D ≤500mm: ISO H8 |
| D >500mm: D+0,0004 x D | |
| Roughness | Ra = 1,6 - 4 μm |
| Rmax ≤ 15 μm |
Installation
The radial shaft seal is installed in an axially accessible housing. The outer diameter and the height of the seal are slightly oversized. The outer diameter is somewhat compressed during installation. Tightening the flange cover also causes slight axial compression of the seal height. The types OS-Q12 and OS-Q13 are installed in pairs back to back, as a rule.
Please read our installation instructions.
