high quality rubber shaft seal

1. 99% for exporting 2. we have our own factory 3. supper quality 4. several years in this field

Weishi Hongli Rubber Co., Ltd. is an export-oriented production enterprise. Our main products include common v-belts, banded belts, narrow belts, color belts and special belts. We also produce othetr products, such as rubber sheets, rubber mats, hoses, oil seals etc. With advanced V-belt production lines in China and the adoption of international standard, our factory has passed the authentication of ISO9001 quality management system.

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

Standard Designs for the V-shaped Water Seals

Cross Sectional Profile
Type	VA	VS	VL	VE
Comments	Most commonly used design	This type is wider and taper. Will achieve a tight fit when used with axle	Narrow cut on axle side. High density construction. Normally used with labyrinth seal	Mainly used under heavy loading conditions as the 2nd seal. It has the largest cross sectional area and allows greater movement of the axle
Specifications	Axle Diameter: 2.7~2020mm	Axle Diameter: 4.5~210mm	Axle Diameter: 105~2025mm	Axle Diameter: 450~2010mm
