Oil seals are vital components that prevent lubricant leakage and block contaminants in power systems across automotive, engineering machinery, agricultural, and industrial equipment. Selecting the right oil seal boosts operational efficiency, extends service life, and reduces maintenance costs.
| High-speed rotation | (e.g., crankshafts, transmission shafts) Use spring-frame rotating seals with high-speed wear resistance. |
| Hydraulic systems | (e.g., cylinders, pumps) Specify high-pressure oil-resistant seals (UN, KDAS, USH types). |
| Heavy load/High temperature | (e.g., commercial vehicles, heavy machinery) Choose fluororubber (FKM) or PTFE seals. |
| Dusty/muddy environments | Select seals with dustproof lips or composite structures (e.g., TC double-lip). |
| NBR | Cost-effective with good oil resistance |
| FKM | Superior heat/oil/chemical resistance |
| HNBR | Enhanced temperature/oil resistance vs. NBR |
| VMQ | Broad temperature range (grease compatible) |
| PU | Excellent abrasion resistance (hydraulic fluids) |
| PTFE | Extreme chemical resistance, low friction |
| TC Seal | Spring-loaded double lip (general bearing sealing) |
| SC Seal | Single lip (low-pressure applications) |
| Cassette Seal | Multi-lip (heavy machinery, long life) |
| Combi Seal | Integrated dust/primary sealing (harsh environments) |
| Hydraulic Seals | UN/USH/KDAS (reciprocating motion systems) |
| Advanced Manufacturing | Fully automated injection molding and CNC machining ensure micron-level precision meeting global standards. |
| Rigorous Quality Control | Every batch undergoes pressure, dimensional, hardness, and seal integrity testing. |
| Premium Material Commitment | We exclusively use certified domestic rubber compounds. Imported materials (DuPont/Daikin) are available for special requirements. We never compromise with inferior materials and stand behind every product. |
| Rapid Delivery | Thousands of stocked molds enable 3-7 day shipping for standard sizes and small batches. |
