A double-row spherical roller bearing in the ISO 222 dimension series. Bore Diameter: 90 mm. Outside Diameter: 160 mm. Overall Width: 40 mm. Rolling Elements: Spherical Roller. Number Of Rows: 2. Bore Type: Straight. Closure Type: Open. Cage Material: Pressed steel. Cage Type: Two pressed steel window cages with a floating guide ring. Internal Clearance: CN. Bearing Material: Bearing steel.
222 — spherical roller bearing, double row, ISO 222 dimension series. The outer ring raceway is a single sphere, so the two roller rows align themselves to it and the bearing tolerates shaft misalignment and housing deflection.
18 — the bore code. Bore Diameter: 90 mm.
CD — two pressed steel cages with a floating guide ring between the rows. The guide ring is not fixed to either ring, so it rides with the rollers and keeps the two rows separated.
The spherical outer raceway lets the inner ring, rollers and cages swivel relative to the outer ring, which absorbs shaft deflection and mounting misalignment without edge-loading the raceway.
Two roller rows carry radial load together and axial load in either direction. Internal Clearance: CN, the normal unmounted radial clearance for a straight bore fitted with an interference fit on the shaft.
Bore Diameter: 3.5433 in. Outside Diameter: 6.2992 in. Overall Width: 1.5748 in. Bore Type: Straight, so the inner ring mounts directly on a cylindrical shaft seat with no adapter sleeve.
Unit Quantity: 1 Pc.
The 90 by 160 by 40 mm envelope is the standard ISO 22218 spherical roller size. The crosses listed share that envelope and the double-row spherical form; cage execution and load rating vary between makers’ designs, and the NSK EA execution is labelled where it differs from this CD cage.
