The features of the 230 series spherical roller bearings are a narrow cross-section and high radial load-carrying capacity, along with self-aligning capability to compensate for shaft deflection and installation error. Their application are concentrated in large industrial equipment subject to heavy load, shock, or shaft deflection.
Narrow Cross-Section Design: Compared with wide series such as 223, the 230 series provides high radial load capacity within the same radial space, making it suitable for compact designs with limited installation space.
Self-Aligning: The outer ring raceway is spherical, automatically compensating for shaft deflection or installation misalignment. The permissible angular deviation is typically around ±2°.
Load Characteristic: Primarily designed to carry heavy radial load, while also accommodating a certain amount of bidirectional axial load; however, their capacity for pure axial load is limited.
Common Variants: Available with tapered bore (suffix K, taper 1:12) for mounting via adapter sleeve; cage material include pressed steel, brass, or plastic; the E1 design (e.g., FAG) increases the load rating through optimized internal structure.
