TvnSeal Engineering Plastics Technology Co., Ltd. is a national high-tech enterprise specializing in the R&D and manufacturing of high-performance sealing materials and special polymer new materials.
Radial lip seal reinforced with a metal outer case. The additional metal inner ring provides excellent rigidity, especially for large diameters.
| Surface Type | Ra | Rmax |
| Contacting Shaft Surface | ≤ 0.4um | ≤ 2.5um |
| Housing | ≤ 6.3um | ≤ 16um |
| The sealing interface surfaces should be polished to remove machining spiral lines from the shaft surface. Grinding is preferred, or localized polishing at the sealing interface only, to avoid leakage caused by spiral lines resulting from machining. Surface hardness: 45-60 HRC. | ||
| Product Features |
| ·Reinforced metal outer case on the oil seal ·Available with an auxiliary dust lip ·Spring-loaded sealing lip ·Suitable for installation in open grooves |
| Product Advantages |
| ·Radial lip seal reinforced with a metal outer case; the additional metal inner ring provides excellent rigidity, especially for large-diameter applications. ·Widely used across general industrial sectors such as pumps, motors, gearboxes, machine tools, etc. ·As a static seal between the groove and the metal housing, its sealing capability is limited. Low-viscosity media may "permeate"; therefore, it is not recommended for sealing low-viscosity fluids. ·The metal case fits securely and precisely into the housing bore. |
