Spherical Roller Bearing

The spherical roller bearing is equipped with a roller-shaped roller bearing between the inner ring having two raceways and the outer ring having a spherical raceway. The center of curvature of the raceway surface of the outer ring is identical to the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and outer casing are deflected, it can be adjusted automatically without increasing the bearing load. Spherical roller bearings can withstand radial loads and axial loads in both directions. The radial load capacity is large, and it is suitable for heavy load and impact load. The inner ring inner diameter is a tapered bore bearing that can be mounted directly. Or use the adapter sleeve and the removal cylinder to mount on the cylindrical shaft. The cage uses a steel stamping cage, a polyamide forming cage and a copper alloy cage. Spherical roller bearings can withstand large radial loads while also withstanding certain axial loads. The outer ring raceway of this type of bearing is spherical, so it has the function of self-aligning. When the shaft is bent or tilted so that the center line of the inner ring and the center line of the outer ring are inclined no more than 1°~2.5°, the bearing can still work. .

The conical inner bore has a taper of 1:1 2 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three evenly distributed oil holes are machined on the outer ring of the bearing. Spherical roller bearings are suitable for heavy loads and impact loads and are widely used in metallurgy, rolling mills, mining, petroleum, paper, cement, sugar and other industries. Sealed spherical roller bearings are designed to withstand the most demanding operating conditions and high service life. For end users, the use of these bearings simplifies maintenance, reduces grease and seal consumption, and eliminates unplanned shutdowns due to premature bearing failure. This greatly reduces operating costs and thus increases operating profit. For OEM customers, the use of sealed spherical roller bearings means the elimination of external seals. Here, the possibility of reducing the size of the machine and reducing the cost will increase the competitiveness of the product, especially if it is considered to ensure trouble-free operation. Sealed spherical roller bearings are suitable for use in harsh environments such as dust, dirt and other contaminants or contaminants. Sealing concept - Sealed spherical roller bearings are fitted with different sealing concepts depending on the bearing series.
