Core Structure: Cage: One-piece solid brass machined cage, high strength, self-lubricating, impact-resistant, low noise; Inner Ring: Small ribs on both ends, no middle retaining ring, no movable spacer ring; Rolling Elements: Two rows of symmetrical spherical rollers; Outer Ring with single spherical raceway, self-aligning capability (allows 1°~2.5° shaft misalignment); Suffix / W33 indicates outer ring with annular oil groove + oil holes for continuous lubrication.

Load Performance: Primarily withstands heavy radial loads, while also capable of handling bidirectional axial loads, impact-resistant; Compared with CC steel cage version: Brass cage has larger oil storage capacity, better stability under low-speed heavy-load conditions; However, roller dimensions and rated radial load capacity are slightly lower than CC type, with lower limiting speed.

Typical Applications: Mining crushers, cement equipment, rolling mills, paper machine rolls, large fans, conveyor drums, sugar mill machinery, heavy-duty reducers and other low-speed, heavy-load, impact-prone applications with axial thrust.

Selection Differentiation: CA: One-piece brass cage, inner ring with ribs on both ends, no middle retaining ring, strong axial load capacity, preferred for low-speed heavy-load applications; CC: Two-piece steel plate stamped cage, with movable spacer ring, higher speed, larger radial load capacity, lower cost.

Usage Guidelines: Allows certain shaft misalignment, no strict coaxiality required; Better suited for low-speed conditions, CC/E types preferred for high-speed applications.
