NTN 22208CC4 double-row spherical roller bearing, straight bore, open, in C4 internal clearance. Series: 222. Bore: 40 mm. Outside Diameter: 80 mm. Width: 23 mm. Bore Type: Straight. Rolling Elements: Spherical Roller. Number Of Rows: 2. Internal Clearance: C4. Closure Type: Open.
22208 — the ISO 22208 size, 40 x 80 x 23 mm, dimension series 22.
C — NTN’s spherical roller design code for this execution.
C4 — radial internal clearance one band wider than C3 and two wider than CN.
Bore: 40 mm. Outside Diameter: 80 mm. Width: 23 mm. Chamfer r: 1.1 mm. Internal Clearance: C4. Rolling Elements: Spherical Roller. Number Of Rows: 2.
Two rows of barrel rollers run on a single spherical raceway ground into the outer ring, so the inner ring, rollers and cage swivel bodily inside the outer ring. Shaft deflection and housing misalignment are taken up by that swivel rather than by edge-loading the roller ends, which is why this is the standard bearing for conveyor pulleys, fans, crushers, screens and long unsupported shafts. Thrust is carried in both directions. C4 clearance leaves extra room before mounting, which is what a heavy interference fit and a large temperature difference across the rings consume.
Shaft abutment diameter da: 47 mm minimum. Housing abutment diameter Da: 73 mm maximum. Shaft or housing fillet radius ras: 1.1 mm maximum. Straight bore, so the inner ring seats directly on the shaft.
Unit Quantity: 1 Pc.
Same-size spherical roller bearings at 40 x 80 x 23 mm: SKF 22208 E, FAG 22208-E1-XL, NSK 22208EAE4, Timken 22208EJ. Searchable variants of the designation: 22208CC4, 22208-C-C4, 22208 C C4, 22208C, 22208 C4. A 22208K is the tapered-bore form of the same size and mounts on an H308 adapter sleeve instead of directly on the shaft. Match the clearance class as well as the size, since C4 and CN behave differently once the interference fit is taken up.
