Decoding the designation

EA is the Ultage high-capacity design with a drawn pressed steel cage. B33 is an annular groove machined into the outer ring outside diameter together with three radial feed holes, the SNR form of the W33 lubrication feature. J30 is C3 internal clearance, greater than normal. Searchable forms of the part number: 22207EAB33J30, 22207 EA B33 J30, 22207.EA.W33.C3, 22207EAW33C3, 22207EAW33, 22207E.

What these specs mean in practice

Dynamic Load Rating: 100 kN. Static Load Rating: 92.0 kN. Limiting Speed: 7,500 r/min on grease, 9,400 r/min on oil. Internal Clearance: C3. Precision Class: P0, ABEC 1. Cage Material: Pressed Steel. Cage Type: Pressed. Bearing Material: Chrome bearing steel. Closure Type: Open. Operating Temperature Range: -30 to +200 °C. Maximum Permissible Misalignment: 1.5°. Two rows of spherical rollers run on a common sphered outer raceway, so the bearing carries heavy radial load together with thrust in either axial direction. The sphered raceway lets the inner ring and roller set swivel inside the outer ring, taking up shaft deflection under load and any angular error between two housings. C3 clearance leaves working room for an interference fit on the shaft and for the temperature difference between inner and outer ring in a heavily loaded drive.

Lubrication feature

Lubricant: grease or oil. The W33 groove distributes lubricant circumferentially around the outer ring and its three radial holes carry it inward to the rolling elements, so the bearing takes fresh lubricant in service from a grease gun, a single-point lubricator, a centralised grease line or a circulating-oil supply. Steel dimensionally stabilised to +200 °C keeps the rings in tolerance at high running temperature.

Quantity and configuration

Unit Quantity: 1 Pc. One complete double-row spherical roller bearing, straight bore, open on both faces, mounting directly on a cylindrical shaft seat.
