241 Series Spherical Roller Bearings

The 241 Series Spherical Roller Bearings are medium-thin, extra-wide heavy-duty spherical roller bearings designed as an upgraded high-load variant of the 240 series. They combine a slim outer ring structure with significantly larger and optimized roller elements, delivering superior load-carrying capacity while maintaining compact radial installation dimensions.

Engineered for extreme heavy-duty and low-speed rotating equipment, the 241 series is widely recognized as a premium solution for large hollow-shaft systems. The enhanced roller geometry increases contact area and load distribution efficiency, resulting in improved durability and reduced wear under continuous harsh operating conditions.

The spherical self-aligning design allows automatic compensation for shaft deflection, misalignment, and installation errors, ensuring stable operation and extended service life in large industrial machinery.

BY Bearings offers the 241 series with multiple cage configurations, including CC stamped steel cages, E optimized designs, and CA/MB machined solid brass cages, supporting different load, speed, and lubrication requirements.

Bearing Designation Example

24192 CAK30/W33

• 241 – Series code

• 2: Double-row spherical roller bearing

• 41: Medium-thin, extra-wide heavy-duty large-bore design

• 92 – Bore code

• Corresponds to a bore diameter of 460 mm

• K30 – Tapered bore (1:30 taper ratio) for heavy-duty adapter sleeve mounting

• CA – Heavy-duty machined solid brass cage

• W33 – Outer ring lubrication groove for centralized lubrication systems

Features and Benefits

• Enhanced Load-Carrying Capacity

  Compared with the 240 series, the 241 series features larger and stronger roller elements, significantly improving radial load capacity and resistance to impact loads.

• Slim Outer Ring Design for Space Efficiency

  Despite its heavy-duty performance, the series retains a thin outer ring profile, making it suitable for equipment with strict radial installation limitations.

• Extra-Wide Roller Structure

  The optimized wide roller design distributes contact stress more evenly, reducing localized wear and improving service life under continuous heavy-load operation.

• Superior Self-Aligning Capability

  The spherical raceway structure compensates for shaft deflection, long-span misalignment, and assembly errors, ensuring stable performance in large rotating systems.

• Optimized for Large Hollow Shaft Systems

  The 1:30 tapered bore design enables secure installation on large shafts using heavy-duty adapter sleeves, simplifying assembly and maintenance.

• High Reliability in Continuous Operation

  Designed for low-speed, high-load environments, the 241 series maintains stable performance in 24/7 industrial operations with minimal maintenance requirements.

• Multiple Cage and Configuration Options

  Available in CC, E, CA, and MB cage types, with optional W33 lubrication grooves and different clearance grades, allowing adaptation to harsh industrial environments.
