Sealing lip
NNK is committed to the best raw materials, and uses advanced technology and equipment to solve oil seal problems for customers. Our products not only ensure the sealing effect, but also minimize the friction force. The service life is longer than the average service life of oil seals. less loss.
1 .Material: There are 7 types of material used for oil seals, they are.
Remove the distributor cap . Before removing the distributor (See Removing and refitting the distributor ), mark the position of the rotor arm so that you can refit it just as it was.

INTRODUCTION TO OIL SEALS AND HOW THEY ARE USED

There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.
These cassette seals are widely used in wheel-end applications, such as the axles of agricultural machinery or off-road trucks.
In conclusion, oil seals are critical components in ensuring the proper functioning of machinery and equipment. By selecting the right seal based on material, design, size, and operating conditions, users can prevent oil leaks, reduce maintenance costs, and prolong the life of their equipment. With a wide range of options available, it is essential to choose a high-quality seal that meets the specific requirements of the application.
