223 Series Spherical Roller Bearings

The 223 Series Spherical Roller Bearings are extra-wide, heavy-duty double-row spherical roller bearings designed for applications involving severe shock loads, high vibration, and continuous heavy-duty operation. Compared with the 222 series, the 223 series features a wider cross-section and increased roller count, delivering significantly higher radial load capacity and improved impact resistance.

With an optimized internal roller arrangement, the load is evenly distributed across the raceway, ensuring stable performance under fluctuating loads and frequent impact conditions. This makes the 223 series one of the most reliable solutions for harsh industrial environments.

The spherical self-aligning structure compensates for shaft misalignment and deflection, ensuring smooth operation and reducing premature wear in demanding working conditions.

BY Bearings supplies the 223 series in multiple cage configurations, including CC stamped steel cages, E optimized designs, and CA/MB machined solid brass cages, enabling stable lubrication retention and adaptability to low-to-medium speed heavy-load applications.

Bearing Designation Example

22330 CAK/W33

• 223 – Series code

• 2: Double-row spherical roller bearing

• 23: Extra-wide heavy-duty series with enhanced load capacity

• 30 – Bore code

• Corresponds to a bore diameter of 150 mm

• CA – Machined solid brass cage (high rigidity, impact-resistant design)

• CC – Stamped steel cage (optional lightweight configuration)

• K – Tapered bore (1:12) for adapter sleeve mounting

• W33 – Outer ring lubrication groove and oil holes for relubrication

• C3/C4 – Increased internal clearance for thermal expansion and high-temperature operation

Features and Benefits

• High Load-Carrying Capacity

  The extra-wide design and increased roller count provide significantly higher radial load capacity compared to 222 series bearings.

• Outstanding Shock and Vibration Resistance

  Designed for harsh environments, the 223 series effectively absorbs impact loads and continuous vibration, ensuring stable long-term operation.

• Optimized Internal Load Distribution

  Evenly distributed roller contact reduces localized stress, improving durability and extending service life under heavy fluctuating loads.

• Excellent Self-Aligning Capability

  The spherical raceway design compensates for shaft deflection and installation misalignment, maintaining stable performance in demanding applications.

• Flexible Structural Options

  Available in multiple configurations, including CC, E, CA, and MB cages, as well as tapered bore (K) and lubrication groove (W33) options.

• Easy Installation and Maintenance

  Tapered bore designs with adapter sleeves simplify installation and removal, improving maintenance efficiency in large equipment systems.
