Spherical Roller Bearings
Spherical roller bearings feature spherical rollers and a spherical outer ring raceway, enabling them to accommodate misalignment and shaft deflection. They are primarily designed to carry heavy radial loads while also supporting moderate axial loads. With their robust design and self-aligning capability, these bearings ensure reliable operation even under misalignment or harsh operating conditions.

Classification of Spherical Roller Bearings by Cage
CA Cage
The CA cage features a machined brass design with high strength and rigidity, making it the most common structure in spherical roller bearings. It is suitable for heavy-load and impact conditions, offering stable performance and good cost efficiency.
CC Cage
The CC cage adopts a pressed steel design, increasing the rolling element ratio to enhance load capacity. It is suitable for high-load applications, but with relatively lower vibration resistance, making it ideal for stable operating conditions.
MB Cage
The MB cage is a two-piece machined brass design that reduces additional stress caused by speed differences between roller rows. It helps protect the bearing and is well suited for high-speed or variable load conditions, ensuring stable operation.
MA Cage
The MA cage is an optimized version of the MB design, offering improved resistance to centrifugal forces and vibration. It is suitable for high-vibration and heavy-duty applications, helping extend bearing service life.
Advantages and Features
- High Load Capacity: The spherical roller design enables the bearing to support heavy radial loads as well as moderate axial loads, making it suitable for demanding applications.
- Excellent Self-aligning Capability: The spherical raceway allows automatic compensation for shaft misalignment and deflection, ensuring stable operation.
- Adaptability to Harsh Conditions: The robust design makes it suitable for shock loads and contaminated environments, providing high reliability.
- Smooth Operation: Optimized contact between rollers and raceways helps reduce vibration and noise.
- Long Service Life: Reduced stress concentration and proper lubrication conditions contribute to extended bearing life.
- Wide Range of Designs: Available in various cage types, sealing options, and configurations to meet diverse operating requirements.
