239/630 CA/W33

Heavy machinery often requires reliable bearing support in tight spaces where housing dimensions are strictly limited. The 239/630 CA/W33 spherical roller bearing addresses this with a 630 mm bore diameter and a thin-section design capable of supporting heavy radial loads along with axial loads in both directions. Its CA designation means it features symmetrical rollers paired with a precision-machined brass cage, providing steady roller guidance and low running friction even during heavy vibration or shock loading. Maintenance is simple because the 239/630 CA/W33 comes with a standard W33 lubrication feature-an outer ring groove accompanied by three lubrication holes for direct grease or oil feeding. By naturally adjusting for shaft misalignment and housing deflections, the 239/630 CA/W33 is widely fitted in steel mill drives, mining equipment, paper production machinery, and heavy-duty gearboxes.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
