E Two pressed window-type hardened steel cages, an inner ring without flanges and a floating guide ring centered on the inner ring (d ≤ 65 mm) or on the cages (d > 65 mm). Optimized internal design for
increased load carrying capacity. Includes the W33 feature.
CC Two pressed window-type steel cages, an inner ring without flanges and a floating guide ring centered on the inner ring
K Bearing with 1 to 12 tapered bore
J Pressed steel cage, inner ring centered (usually omitted with E or CC suffixes)
W33 Three oil holes and circumferential groove in outside diameter
