22328 CC/C3W33

The 22328 CC/C3W33 is a metric-series spherical roller bearing recognized for its unique ability to thrive in challenging operational environments. Designed with two rows of symmetrical rollers, it handles significant loads, accommodating high radial forces along with bidirectional axial loads. The key technological advantage of this design is its inherent self-aligning quality, which effectively mitigates issues arising from static or dynamic misalignment, such as shaft deflection. This feature prevents undue stress concentration and premature failure, proving invaluable for demanding machinery in the mining, cement, and power generation industries. The standard bore diameter measures 140 mm, paired with a 300 mm outside diameter and a 102 mm width.

This specific variant is customized to provide maximum uptime and efficiency. The internal geometry, indicated by the 'CC' feature, optimizes roller path and guidance, minimizing friction and heat generation under heavy operational strain. The 'C3' internal clearance is intentionally looser than standard, a necessary specification for applications involving thermal growth or rapid acceleration, ensuring the bearing maintains proper running clearance. Furthermore, the 'W33' modification is a critical maintenance detail: an integrated lubrication groove and holes in the outer ring allow for efficient and regular replenishment of grease or oil, significantly extending the bearing's lifespan and reducing the overall maintenance frequency.
