23138 CC/C3W33

The 23138 CC/C3W33 spherical roller bearing stands out as an exceptional choice for punishing industrial environments that subject machinery to substantial radial and axial forces, often in the presence of shaft bending or housing distortion. Its inherently self-aligning structure means it compensates for static or dynamic misalignment, operating smoothly where rigid bearings would quickly fail. This model, with principal dimensions of 190 mm inner diameter, 320 mm outer diameter, and a 104 mm width, is characterized by its superior load ratings and robust construction. The modern CC design optimizes internal geometry, incorporating two durable pressed steel cages for precise roller guidance and ensuring that the bearing maintains peak performance even at its limiting speed.

A significant aspect of the 23138 CC/C3W33 is the special attention paid to thermal management and sustained lubrication. The C3 designation specifies a loose internal radial clearance, which effectively accommodates thermal expansion under high operating temperatures and prevents stress build-up from tight interference fits. Crucially, the W33 feature includes a lubrication groove and three integrated holes in the outer ring. This relubrication capability allows maintenance personnel to easily replenish grease or oil, ensuring that the rolling elements remain properly lubricated and drastically extending the bearing's service life, making it a highly reliable and cost-effective component for large-scale equipment.
