230 Series Spherical Roller Bearings

The 230 Series Spherical Roller Bearings are lightweight, thin-section, double-row self-aligning roller bearings specifically engineered for large-diameter shafts and compact heavy-duty rotating equipment. Featuring a large bore diameter, relatively small outside diameter, and wide cross-section design, these bearings provide excellent load-carrying capacity while minimizing installation space requirements.

The self-aligning spherical raceway design automatically compensates for shaft deflection, mounting errors, and housing misalignment, ensuring stable operation and extended service life under demanding industrial conditions. Compared with standard spherical roller bearings of the same bore size, the 230 series offers a lighter weight structure, reduced friction, and improved energy efficiency.

BY Bearings supplies the 230 series in multiple cage and design configurations, including CC stamped steel cage, E optimized design, and CA/MB machined brass cage options to meet different lubrication, load, and operating requirements.

Bearing Designation Example

23048 CA/W33

• 230 – Bearing series code

• 2: Double-row spherical roller bearing

• 30: Thin-wall, wide-section, large-bore series

• 48 – Bore code

• Corresponds to a bore diameter of 240 mm

• CA – Machined solid brass cage

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

• W33 – Lubrication groove and three lubrication holes in the outer ring for efficient relubrication

• C3 – Increased internal clearance for high-temperature and heavy-duty operating conditions

Features and Benefits

• Large Bore, Space-Saving Design

  The thin-wall outer ring structure with a large bore diameter is ideal for hollow shaft applications, reducing radial installation space and supporting lightweight equipment design.

• High Load Carrying Capacity

  The optimized double-row roller arrangement provides excellent radial load capacity while accommodating moderate axial loads in both directions.

• Superior Self-Aligning Performance

  The spherical raceway design allows a large self-aligning angle, effectively compensating for shaft misalignment, housing errors, shaft deflection, and long-term eccentric operation.

• Reduced Weight and Energy Consumption

  Compared with conventional thick-section bearings of the same bore size, the 230 series is lighter in weight, reducing rotational friction and lowering overall equipment energy consumption.

• Wide Size Range

  A comprehensive range of bore diameters makes the series suitable for medium and large industrial hollow-shaft transmission systems and rotating machinery.

• Reliable Operation in Heavy-Duty Applications

  Designed for low-speed and heavy-load operating environments, ensuring long service life and stable performance even under harsh industrial conditions.
