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.
For TGR fabric-reinforced oil seals, the housing bore must be axial to facilitate axial installation of the seal and minimize seal tilt.
| Surface Type | Ra | Rmax |
| Contacting Shaft Surface | ≤0.6um | ≤2.5um |
| Housing | ≤4.0um | ≤15.0um |
| The mating sealing contact surfaces shall be processed by cross-feed non-directional lapping, to prevent leakage caused by spiral machining marks. The surface hardness shall be approximately 60 HRC (minimum hardened layer thickness: 0.5 mm).As peripheral linear speed rises, the roughness Ra of the contact surface shall be increased appropriately; the surface must not be excessively smooth to maintain a proper lubricating oil film. The recommended minimum value: Ra min = 0.1 um.At a cutting depth c = Rz/2 and reference line Cref = 0%, the material bearing length ratio Mr shall range from over 50% up to a maximum of 90%.Corrosion, scratches and pores on the shaft surface must be avoided. | ||
| Product Features |
| Integrated design of fabric-reinforced outer shoulder of the oil seal and pure rubber sealing lip, with spring preloaded sealing lip design. |
| Product Advantages |
| 1.In heavy machinery manufacturing, it is commonly used for shaft ends of grinders, metallurgical rolling mills or drive shafts of large gearboxes under lubricated operating conditions. 2. The outer edge of the oil seal made of fabric is particularly robust, with excellent static sealing performance; 3. The sealing lip maintains long-lasting radial pressure contact; 4. The sealing lip is highly wear-resistant; 5. Split seals are available for easy installation. |
