1. Double seal design: Sealed Spherical Roller Bearings usually adopt a double seal structure with seals on both the inner and outer rings. The sealing ring or sealing gasket between the inner and outer rings effectively prevents the leakage of grease and can resist the intrusion of dust, moisture or chemicals in the external environment. This design not only protects the grease inside the bearing, but also extends the service life of the bearing and reduces the frequency of maintenance and replacement.
2. Professional sealing materials: Sealing materials are usually made of high-performance rubber or synthetic rubber with elasticity and wear resistance. These materials can maintain their sealing performance under various working conditions, such as high temperature, low temperature, chemical media and mechanical vibration. The selection of sealing materials is crucial. They must not only effectively seal the bearing, but also ensure long-term reliability and stability.
3. Pre-filled grease: Sealed Spherical Roller Bearings are usually pre-filled with an appropriate amount of high-performance grease when manufactured. This grease not only reduces friction and wear, but also effectively seals the inside of the bearing to prevent the entry of external contaminants. Pre-filled grease usually has anti-oxidation and anti-aging properties, and can maintain its lubrication effect during long-term operation, reducing lubrication intervals and maintenance costs.
4. Anti-pollution ability: Due to its efficient sealing structure, Sealed Spherical Roller Bearings can effectively prevent external contaminants from entering the interior of the bearing. These contaminants may include moisture, dust, chemicals or other solid particles, which may cause premature failure or damage to the bearing during long-term operation. Therefore, good sealing performance is one of the key factors to ensure long-term stable operation of the bearing and reduce maintenance requirements.
5. Easy to install and maintain: The sealing structure of Sealed Spherical Roller Bearings is designed as non-contact or low-contact, which makes the bearing easier to install and maintain. Users can easily inspect and maintain the bearing, relubricate or replace the seal without disassembling the entire bearing unit. This design not only saves time and cost, but also improves the reliability and availability of the equipment.
