Sealed Spherical Roller Bearing Manufacturer

Sealed spherical roller bearing is an upgraded design of the spherical roller bearing. Like ordinary open spherical roller bearings, it has two rows of drum rollers, one spherical raceway on the outer ring and two rollers on the inner ring. The raceway is inclined at an angle relative to the bearing axis. The raceway has a certain radian. According to the different designs of the rollers and cages, there are different processing methods. In addition, there is a sealing design at both ends of the bearing (the sealing cover is made of nitrile rubber), which can prevent the entry of dust, particles, and dust, and can keep lubricating oil or grease in a sealed environment to lubricate the raceway and reduce The temperature of the bearing during operation), so as to ensure the normal operation between the raceway and the roller of the bearing, and ensure the service life of the bearing.

The radian design of the raceway makes it have self-aligning performance, so it is not easily affected by the angle between the shaft and the bearing housing on the error or shaft bending, and is suitable for the occasions where the installation error or the shaft disturbance causes the angle error. In addition to radial loads, the bearings can also withstand axial loads acting in both directions.

The inner bore of the sealed spherical roller bearing has two types: cylindrical bore and tapered bore. The taper of the conical taper hole is 1:30 and 1:12. This conical inner hole bearing is equipped with an adapter sleeve or a withdrawal sleeve. , the tapered inner hole self-aligning ball bearing can be easily and quickly assembled on the optical shaft or stepped shaft.

By design, Sealed spherical roller bearings can accommodate very heavy radial and heavy axial loads in applications prone to misalignment or shaft deflections. Sealed spherical roller bearings have the same features and internal design as basic design spherical roller bearings, but are equipped with contact seals fitted in recesses in the outer ring.

The bearings are supplied lubricated with a high-performance TKW grease. For many application conditions, the bearings do not require relubrication and can be considered maintenance-free.

The effective contact seals keep lubricant in and contaminants out and of the bearing, providing significantly increased service life in many applications where there are high levels of contamination.
