Deep groove ball bearing seals bearing is a key component in the harsh environment of the normal operation of the bearing seals protect bearings from erosion and pollution. Bearing in good clean lubrication conditions, to extend the life of the bearing.

In general, deep groove ball bearing seals bigger role than the dust cover, and limited rotation flexibility and lower speed rotation. Bearing seals in the design, performance and must consider lubricant delivery system and ideal working conditions.

For bearing applications in use to be subjected to high loads, strong impact and prevent water and rust particles and other debris intrusion, while the development of a new ultra high load capacity of the sealed type, clean and lubricated bearing seals.

Experience has shown that pollution in the working conditions, easily entering the bearing debris particles, and these debris particles can damage the raceways, causing stress concentration. In addition, if uneven lubrication of the metal surface of the hard contact, resulting in small "peeling" damage, can also cause stress concentration contact areas, both the result of stress concentration resulting metal surface crack spread, and ultimately reduce bearing life.

Studies have shown that by changing the organization bearing steel, the bearing can be improved at the edge of the working life of impurity contamination conditions under lubrication or improve the bearing capacity of the release of stress concentration on the edge.

The best protective measures are bearing practical: When the impurities appeared, stop it. New deep groove ball bearing seals of both the above two advantages. The new seal bearing hole solve both inhibit the formation of negative pressure within the bearing to prevent water, so that the primary seal is not directly exposed to water, the water from "breathing", but also play a barrier to impurities in the recess function at the trough. Conventional bearing seals in rotating and the stationary linear contact state is maintained tight seal properties of high strength, while the work of such a sealing member, the contact surface contact instead of linear, rotary bearing to accommodate the requirements of the seal, a tight seal either, do not have a big negative.

In order to confirm the effectiveness of the new hole bearing seals, in the test, the bearing operating speed range from 100r / min increased to 700r / min, and continued to exert a radial load of 294kN, while about 100L / min of water spray. General pass bearing seals in this period, the negative pressure increases, and the new hole bearing seals inhibiting the negative, to ensure the normal operation of the work.
