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.
Widely applied across all segments of general industry, including pumps, electric motors, gear reducers, machine tools and other equipment.
| Surface Type | Ra | Rmax |
| Contacting Shaft Surface | ≤0.4um | ≤2.5um |
| Housing | ≤10.0um | ≤25.0um |
| The mating sealing contact surfaces shall be polished to remove directional spiral lines on the shaft surface. It is recommended to use lapping or local lapping and polishing only on the mating sealing contact surfaces, to prevent leakage caused by spiral machining marks. The surface hardness shall be 45-60 HRC. | ||
| Product Features |
| 1. Oil seal outer edge: metal skeleton; 2. Oil seals with dustproof secondary lips are available; 3. A spring is installed at the sealing lip position; 4. Can be installed in open grooves; |
| Product Advantages |
| 1. Widely used in various fields of general industry, such as pumps, electric motors, gear reducers, machine tools, etc.; 2. The metal skeleton is particularly stable and precise when assembled in the housing bore; 3. The static sealing performance between the groove and the metal shell is limited, low viscosity media can "permeate", and it is not recommended for sealing low viscosity media; 4. Excellent radial rigidity, suitable for large diameters; |
