A double-row spherical roller bearing in the SKF 213 series with a tapered bore. Nominal bore 50 mm, outside diameter 110 mm, width 27 mm. Two rows of barrel-profile rollers run on a common spherical outer raceway, so the assembly accommodates up to 1.5° of shaft-to-housing misalignment while carrying heavy radial load and thrust in both axial directions.
21310 — ISO base: 213 dimension series, bore code 10 for a 50 mm nominal bore.
CC — SKF cage and internal design code: two pressed steel window cages with an inner ring guide ring.
K — 1:12 tapered bore.
No clearance suffix — internal clearance is normal, CN.
Bore Diameter: 50 mm (1.9685 in), 1:12 tapered. Outside Diameter: 110 mm. Width: 27 mm. Rolling Elements: Spherical Roller. Number Of Rows: 2. Bore Type: Tapered 1:12. Seal Type: Open. Cage Material: Pressed steel. Internal Clearance: CN (normal). Maximum Permissible Misalignment: 1.5°. Series: 213 series (21300). Base Number: 21310. Material: Chrome Steel. Unit Quantity: 1 Pc.
The 1:12 tapered bore mounts on a tapered adapter sleeve over a plain cylindrical shaft. Matching accessories: adapter sleeve H310, KM 10 locknut, MB 10 lockwasher. The 213 series is the shallow cross-section spherical roller family.
Straight-bore 21310 CC shares the envelope but seats directly on a machined shaft step and takes no adapter sleeve. MPN variants: 21310CCK; 21310-CCK; 21310 CCK; 21310CK; 21310-CC-K; 21310CKJ; 21310CCKJ; 21310 CC K.
A 1:12 tapered bore.
Two pressed steel window cages with an inner ring guide ring.
