Decoding the designation

Base Number: 22209, setting the 45 x 85 x 23 mm envelope. EA is the high-capacity execution with a pressed steel cage. B33 is the lubrication feature, written W33 in the ISO suffix form. J30 is the C3 radial internal clearance group. Bore Type: Straight. Searchable variants of the number: 22209EAB33J30, 22209EAW33C3, 22209.EAW33C3, 22209-EA-B33-J30, 22209 EA W33 C3, 22209EJ W33 C3.

Lubrication feature

Relubrication Feature: annular groove in the outer ring outside diameter with three radial holes through to the rolling elements. Lubricant: grease or oil. The groove distributes lubricant circumferentially around the outer ring and the three radial holes carry it inward to both roller rows, which suits a grease gun, a single-point lubricator, a centralised grease system, or circulating-oil and oil-mist feed through the same passages.

Cage and internal design

Cage Type: Pressed. Cage Material: Steel. Permissible Misalignment: 0.5° at normal load. The two roller rows share one concave outer-ring raceway, so the inner ring and roller set swivel within the outer ring and absorb shaft deflection and housing misalignment.

What these specs mean in practice

Two rows of spherical rollers carry high radial load and take thrust in both directions. C3 clearance is one step greater than normal and absorbs the running clearance lost to an interference fit on the shaft and to a temperature gradient across the bearing, so it suits a heavier press fit and a hotter inner ring. Maximum Operating Temperature: 200 °C. The straight bore mounts directly on the shaft seat.
