SKF 21313E/C3 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 = 65 mm per ISO 15.

Compatibility

ISO 15 boundary-plan interchange — the numeric bore-code block is portable across every ISO 15 bearing manufacturer (SKF, Timken, NSK, NTN, FAG, Koyo, NACHI). Confirm suffix compatibility on cage, seal, clearance and precision class before substitution.
