Decoding the designation

EA is the Ultage high-capacity design with a drawn pressed steel cage. K is a 1:12 tapered bore. B33 is an annular groove machined into the outer ring outside diameter 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: 22216EAKB33J30, 22216 EA K B33 J30, 22216.EAK.W33.C3, 22216EAKW33C3, 22216EK, 22216CCK, 22216CKJ, 22216CCKJ, 22216CK, 22216E.

What these specs mean in practice

Dynamic Load Rating: 278 kN. Static Load Rating: 287 kN. Limiting Speed: 3,700 r/min on grease, 4,600 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, and the inner ring and roller set swivel inside the outer ring to absorb shaft deflection under load and angular error between two housings. On a double-row spherical roller the static rating sits above the dynamic rating because the load is shared across two rows of long rollers in simultaneous contact. C3 clearance leaves working room for the interference fit on the sleeve and for the temperature difference between inner and outer ring under heavy load.

Bore form and mounting hardware

The 1:12 tapered bore sets radial internal clearance by how far the inner ring is driven up the taper, so running clearance is adjusted at assembly rather than fixed by the shaft tolerance. Mounts on an H316 adapter sleeve, which has a 70 mm cylindrical shaft seat and an 80 mm tapered outside diameter matching this bore, secured by a KM16 locknut and an MB16 lockwasher.

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. The rings are dimensionally stabilised for running temperatures to +200 °C.
