63004-2RS is extra-wide single row deep groove ball bearing.

• 2RS: Double-sided contact NBR rubber seals, effectively block dust, moisture and debris

Compared with standard 6204 bearing, it adopts wider width design to improve load capacity. It can bear radial load and moderate bidirectional axial load simultaneously. Sealed structure retains pre-filled grease for long maintenance-free operation. Open type 63004 is available for continuous oil lubrication scenarios. Widely used on agricultural machinery, small vehicle wheel hubs, water pumps, garden machinery and general transmission equipment.
