Product Description

Spherical outer ring ball bearings are essentially a variant of deep groove ball bearings, characterised by their spherical outer ring surface. This allows them to fit into a corresponding concave spherical surface within the bearing housing, thereby achieving self-alignment. Primarily designed to withstand combined radial and axial loads where radial loads predominate, they are generally unsuitable for bearing axial loads alone. Both the inner and outer rings of this bearing type can be mounted separately. These bearings do not permit axial misalignment between the shaft and housing. Under radial loading, they generate additional axial forces and are typically used in conjunction with bearing housings. They are primarily employed in transmission components where alignment is difficult, installation deviations are likely, or shaft deflection occurs.

Features and Advantages

● Self-aligning capability

The spherical outer ring structure compensates for misalignment between the shaft and housing bore, accommodating installation errors and shaft deflection.

● High load capacity

Capable of withstanding not only radial loads but also certain axial loads, whilst operating with low noise levels.

● Robust load-bearing capability

Can handle substantial radial loads and minor axial loads, withstanding impact and suitable for heavy-duty applications.

● Excellent sealing performance

Features integrated dust and water seals, suitable for harsh environments such as high dust or humidity.

● Maintenance Convenience

Certain models permit grease replenishment, extending service life and reducing maintenance costs.

Product Applications

Widely employed in agricultural machinery, conveying equipment, textile machinery, printing presses, food processing machinery, woodworking machinery, construction machinery, mixers, crushers, mining, metallurgy, building materials, and other demanding environments requiring high self-alignment and sealing performance.
