NSK 63203DDU, a single-row deep groove ball bearing from NSK’s wide-width cartridge family. Bore: 17 mm. Outside Diameter: 40 mm. Width: 11/16 in (approximately 17.5 mm). Number Of Rows: 1. Rolling Elements: steel balls. Closure Type: contact rubber seals both sides. Internal Clearance: CN (normal). Lubricant: factory grease, sealed. Bearing Material: through-hardened bearing steel. Series: 63200 light cartridge. The cartridge series keeps the 6203 bore and outside diameter and widens both rings, which gives bolt-in cartridge housings, farm and turf gearboxes and idler assemblies a wider seat and more ring support in the same diameter.
6 — single-row deep groove ball bearing.
32 — NSK wide-width cartridge prefix applied to the 02 series envelope.
03 — bore code, giving a 17 mm bore.
DDU — contact rubber seals on both sides. DU is one seal, VV non-contact rubber, ZZ metal shields.
No clearance suffix — CN normal radial internal clearance. A 63203DDUC3 is the greater-clearance execution and a separate part.
X28 — carton reference carried as a searchable variant.
Contact rubber seals rub on the inner ring, so they hold out dust, washdown spray and grit, and the bearing arrives pre-greased and closed for life. The trade is slightly more running torque and a lower speed ceiling than a shielded ZZ or a non-contact VV.
Width is the other point of difference. This ring is 11/16 in wide against 12 mm on a standard 6203, and the 63203 seat is cut for the wider ring.
Unit Quantity: 12 Pcs. One lot of twelve bearings.
Direct interchanges are same-envelope wide cartridge bearings with contact seals both sides: 63203-2RS, Koyo 63203-2RS, NTN 63203LLU, and Fafnir/Timken wide-inner cartridge bearings of matching width. The 6203DDU at 12 mm width, the 63203ZZ with metal shields and the 63203DDUC3 at greater clearance are related sizes. Searchable variants: 63203DDU, 63203-DDU, 63203-DDU-X28, 63203RS, 63203-2RS.
