unnecessary. Bearings with sealing covers on both sides (whether rubber sealing covers or steel plate stamping sealing covers) do not need to be oiled.
In order to achieve the optimal service life of the bearing, what grade of grease should be filled and the filling amount of grease are the best and most scientific solutions obtained through countless practical experiments. It is generally believed that the grease consumption life is equivalent to the bearing life. In addition, the design of the sealing cover, the distance from the inner ring, contact, non-contact, or labyrinth are all designed. Disassembling and assembling the sealing cover when refueling will inevitably affect its effect, thereby affecting the service life of the bearing.
What are the bearing sealing methods?
The sealing methods of rolling bearings can be divided into two categories: contact sealing and non-contact sealing. The so-called bearing with built-in seal means that the bearing itself is made into a device with sealing function. Such as bearings with dust covers, sealing rings, etc. This seal takes up a lot of space. The so-called bearings with additional sealing function equipment are sealing equipment with various functions made inside the equipment end cover and so on.
1. Contact seals include felt ring seals, sealing ring seals, etc.
2. Non-contact seals include axial curved seals, radial curved seals, oil groove seals, back-up ring seals, etc.
Bearings within this life should have initial fatigue damage (flaking or chipping) on any of their bearing rings or rolling elements. However, whether in laboratory tests or in actual use, it can be clearly seen that bearings with the same appearance under the same working conditions have very different actual lifespans.
In addition, there are several different definitions of bearing "life", one of which is the so-called "operating life", which indicates the actual life that a bearing can achieve before it is damaged. Damage is usually not caused by fatigue, but by wear and tear. Caused by wear, corrosion, seal damage, etc.
Bearing sealing ring, a kind of bearing seal, especially a ball bearing sealing ring, the ball bearing sealing ring has two circular protrusions extending upward on one end face of the annular shape, and the diameter is smaller The inner diameter of the protrusion matches the outer diameter of the inner ring of the ball bearing, and the larger diameter protrusion matches the outer diameter of the ball ring of the ball bearing; the inner diameter of the sealing ring is not smaller than the inner ring of the ball bearing. the inner pore diameter. It has the characteristics of preventing grease from catching fire, avoiding frequent refueling and having a simple structure. It is widely used on bearings.
A bearing sealing ring, characterized in that: two circular protrusions extend upward on one end face of the annular shape, and the inner diameter of the smaller diameter protrusion is equal to the outer diameter of the inner ring of the ball bearing. The larger diameter protrusion matches the outer diameter of the ball ring of the ball bearing; the inner aperture of the sealing ring is not smaller than the inner aperture of the inner ring of the ball bearing.
