Gcr15 Steel Double Row Spherical Roller Bearings with Grease Lubrication 21307MB/W33

Product Description:

Spherical roller bearings are a specific type of rolling bearings that have the ability to withstand large radial loads and select axial loads. Often these bearings are designed with centers of the inner and outer rings that can be tilted to the axis. This tilting feature enables them to align their centers automatically.

Compared to other types, spherical roller bearings have double-row rollers and a spherical raceway on the outer ring. Also, two raceways on the inner ring are tilted at an angle relative to the bearing axis.

The design of spherical roller bearings caters to adjust the axis misalignment caused due to deflection or non-concentricity of the shaft or housing. Due to their customizable features, they perform exceptionally well, and are widely preferred in industrial applications where shaft or housing deflection is inevitable.

Overall, spherical roller bearings offer an efficient and dependable solution for applications that have high loads and need accurate alignment.

Features:

The spherical roller bearing is designed with a spherical raceway between the inner and outer rings. This design allows the bearing to have automatic self-aligning ability, meaning that it can adjust the deviation of the axis and maintain stable operation even if the shaft or housing is deflected or not concentric. As a result, installation accuracy requirements are greatly reduced, and the service life of the bearing is prolonged.

The double-row roller structure and the spherical raceway design between the inner and outer rings enable the spherical roller bearing to withstand large radial loads and certain axial loads. This design effectively disperses the load and reduces stress concentration of the bearing, ensuring stable operation even when bearing heavy loads.

The automatic self-aligning and high load-bearing capacity of the spherical roller bearing provide good stability and durability when bearing impact loads. This feature makes it particularly suitable for mechanical equipment requiring to withstand impact loads.

The inner hole of the spherical roller bearing is cylindrical and conical. The tapered inner hole bearing is equipped with a tightening sleeve or a withdrawal sleeve, which can be easily assembled on the smooth shaft or the stepped machine shaft. This design enables the spherical roller bearing to adapt to a variety of installation requirements and improves its applicability.

The spherical roller bearing can maintain a stable state during operation, reducing vibration and noise. This helps to improve the operating efficiency and service life of mechanical equipment, while also reducing noise pollution to the surrounding environment.

The spherical roller bearing is easy to maintain as it has a relatively simple disassembly and installation process. When replacement or maintenance is required, it can be disassembled and installed quickly, reducing downtime and maintenance costs.
