Deep groove ball bearing seals applications

Deep groove ball bearing is the bearing seal member in the normal operation in the harsh environment of the key components, bearing seals protect bearings from erosion and pollution of the bearing lubrication in a good clean conditions, extending bearing life.

Generally, deep groove ball bearing seals greater role than the dust cover, and by rotating flexible and low speed rotation restrictions. Bearing seals in the design, we must consider the performance of lubricants and conveyor systems and ideal working conditions.

For bearing applications in use to withstand high loads, a strong impact force and prevent water and dust particles such as rust invasion, and developed a new type of high load capacity, sealed, clean and lubricated bearing seals.

Experience has shown that in a polluted working conditions, easy to enter the bearing clastic particles, and these particles can damage the raceway debris, causing stress concentration. Also, if uneven lubrication, hard contact of the metal surface, resulting in a slight "peeling" corrupted, the contact area can lead to stress concentration, so that these two results of the stress concentration of the metal surface crack spread and ultimately shorten bearing life.

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

The best practical protection measures are bearing: When the impurity one appears, then stop it. New deep groove ball bearing seals of both these two advantages. The new hole type bearing seals only solve suppress a negative pressure in the bearing to prevent the water, the main sealing member is not directly exposed to water, the water from "breathing", but also play an impurity blocking the recess slot at the function. Conventional bearing seals the rotating and the stationary state is a linear contact, to maintain the strength of the tight sealing performance of the sealing member and this work, the contact instead of linear contact with the surface to accommodate the bearing rotating sealing requirements, both tight seal, not produce a large negative pressure.

To confirm the new hole type bearing seals the effectiveness of the test, the bearing operating speed range to 100r/min 700r/min, and 294kN radial load is continuously applied while the water spray of about 100L/min. General hole bearing seals in this period, the negative pressure increases, while the new-hole bearing seals inhibited the negative, to ensure the normal operation of the work
