SKF 23172CAC/C08W509 — Spherical roller bearing
SKF · Bearings & Power Transmission · Spherical Roller Bearings
SKF 23172CAC/C08W509 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 = 45 mm per ISO 15. Designation follows the ISO 15 / DIN 623 alphanumeric convention where the numeric block encodes the dimension series and bore code; suffixes after the numeric block declare cage, closure, precision, clearance and lubricant execution. Genuine SKF supply carries the SKF logo etch on the outer ring face and hologram-authenticated packaging.
