SKF 239/850CA/W33 spherical roller bearing. Self-aligning double-row spherical roller bearing designed for very heavy radial load with concurrent axial load in either direction, and inherent tolerance for shaft-to-housing misalignment. Two rows of symmetrical rollers ride on a common concave outer-ring raceway. Common execution suffixes cover CC (window-type cage), CA (machined brass cage), EK (tapered bore for adapter-sleeve mount), and W33 (annular groove and three lubrication holes in outer ring). Manufactured to ISO 492 Class Normal / P6. Bore diameter d = 165 mm per ISO 15.
