Sealed bearing function
Keep the bearing smooth and normal working environment, give full play to the function of the bearing, prolong the service life of the bearing, and have a suitable seal for the rolling bearing to avoid the leakage of the lubricant and the intrusion of dust, moisture or other dirt. This is beneficial to the protection of the bearing.

Sealed bearing can be divided into self-sealing and external sealing. The so-called bearing with its own seal is to make the bearing itself into a device with a sealing function. Such as bearing with dust cover, sealing ring and so on. The so-called bearing plus sealing function equipment is a sealing equipment with various functions made inside the equipment end cover.
The following factors should be considered when adding seals to bearings:
The advantages of the bearing structure of the shaft, the allowable point of view error, the bearing lubricant and type (grease and lubricating oil), the operating temperature of the bearing, the operating environment of the bearing, the large space occupied, the peripheral speed of the sealing surface, and the production cost.

Additional sealing is divided into two types: non-touch and touch.
Touch seals Touch seals are seals where the seal is in contact with its relative moving parts and has no voids. Because of the direct contact between the seal and the cooperative parts, this kind of Sealed bearing has a large conflict during operation, and generates a large amount of heat. Therefore, it is only suitable for medium and low speed operating conditions. Sealed bearings such as felt seals and leather cup seals are commonly used in touch seals, which are used in different occasions. According to the operating conditions of the Sealed bearing and the requirements of the operating environment for the degree of sealing, various sealing methods are often used in engineering design to achieve a better sealing effect.

A non-touch seal is a seal in which the seal does not touch the parts that move relative to it, and there is an appropriate gap. Sealed bearing in this way has almost no conflict and heat during work, no wear and tear, and is uniquely suitable for high-speed and high-temperature occasions. Non-contact seals are commonly used in various types of sealed bearings, such as void type, labyrinth type and gasket type, which are used in different occasions. It is best to keep the gap of the non-touch seal as small as possible.
