With a good reputation among customers, our products with the trade mark of "MOLI" and "DOUBLE LION" have been exported to more than 10 countries and regions.
Type: VA VE VL VS
Specifications 1. good abrasive resistance,
2, low permanent deformation
3. external mechanical impact endurance
Features:1).Excellent durability and flexibility in using.
2).Specially designed cords enhance durability and length stability.
3).Excellent in resistance against heat,oil and wear..
4).Show stable in high speed rotation.
5). Resistant to heat, oil, fatigue, aging and friction due to excellent and special frame
6). Large power, high speed, long service life, small distortion, less space occupying7)The V-shaped seal possesses the following advantages: -Pure elastic rubber construction without any additions of metals -Eases the workload on design processes and easily installed with no remachi-ning needed -Eliminates the need for re-machining of the axle surface and complies with the surface precision and hardness for the axle surface. Therefore axles do not necessarily need to be hard. -Easy installation and removal; high reliability -Small surface contact with other parts, thereby lowering frictional forces and heating due to friction resulting in a longer life span -Doubles as a medium for sealing effect and prevents dust from contamination the interior
Applications:
1.Applied for electric motors, internal combustion engines and power transmission equipments.
2.Adopting scientific technical composition, specially selected first class rubber material and low elongation reinforcing,
3.MOLI brand Common rubber seal is in accordance with related international standard.
4. high wearing resistance, low elongation and long life.
Using: rubber seal is used widely in power transmission of mechanical equipments driven by electric motors and diesel engines.5. V-shaped seals are normally manufactured using 2 types of raw materials: 1.Shore Hardness Type A 60 RP Operating Temperature: -40 ~ +100 Degrees Celsius Medium: Mineral Oil, Air, Water, Milk-like liquids, Fats 2.Shore Hardness Type A 65 FKM Operating Temperature: -20 ~ +180 Degrees Celsius Medium: Mineral Oil, Fats and Oil Composites, Acids, Alkalis
Structure: Refer to GB/T10708.3-2000 standard series when designing.
Material: rubber-plastic ,PR,FKM used in general fluorine rubber also used in special occasions
