Spherical Roller Bearings

Spherical Roller Bearings for Heavy Loads and Misalignment

Spherical roller bearings are designed for demanding rotating equipment where heavy radial loads, axial loads, shaft deflection, vibration, or alignment variation can create challenges for conventional bearing arrangements. Their self-aligning internal geometry allows the bearing to accommodate a certain degree of misalignment between the shaft and housing while maintaining reliable rolling contact.

Oukai provides Spherical Roller Bearings for crushers, vibrating equipment, mining machinery, gearboxes, conveyors, paper machinery, rolling mills, industrial transmissions, and other heavy-duty equipment.

Available Oukai Spherical Roller Bearing Models

Our current product range includes models such as 21308 CCW33, 21306 CCK, 21309 CCW33, and 21307 CCK. These models provide different dimensional and configuration options for industrial machinery and replacement requirements.

The 21308 CCW33 Spherical Roller Bearing, for example, can be considered for equipment such as reducers, paper machinery, crushers, vibrating screens, rolling mill gearboxes, printing machinery, and other transmission systems.

Key Advantages of Spherical Roller Bearings

Self-Aligning Capability

The spherical outer raceway enables the bearing to tolerate a certain degree of shaft or housing misalignment. This makes spherical roller bearings especially valuable in long shafts, heavy machinery, fabricated structures, and equipment exposed to housing deformation.

Heavy Radial Load Capacity

The roller-type design provides a relatively large contact area between the rolling elements and raceways, making these bearings suitable for heavy radial loading.

Combined Load Capability

Spherical roller bearings can also carry axial loads in addition to radial loads, providing greater flexibility for industrial equipment operating under complex load conditions.

How to Select a Spherical Roller Bearing

Selection should consider bore diameter, outside diameter, width, radial load, axial load, speed, shaft and housing fits, lubrication, temperature, contamination, expected misalignment, and maintenance requirements.

In mining and material-processing environments, dust, vibration, and shock loading can be particularly important. In continuous industrial equipment, lubrication reliability and maintenance intervals may have a major influence on bearing life.

Compare Other Oukai Bearing Types

For applications with relatively low misalignment and higher rotational speed, buyers can also review Deep Groove Ball Bearings.

Where combined radial and axial load control is the primary concern, Tapered Roller Bearings may be another suitable option.
