What is a 6004 2RS Ball Bearing?
The 6004 2RS bearing is a single-row deep groove ball bearing with rubber seals on both sides. The designation "6004" refers to its dimensional series, and "2RS" indicates two rubber seals. It prevents dust, debris, and moisture from entering, while retaining lubricant inside. This makes it a preferred solution for electric motors, automotive parts, pumps, and industrial machinery.

6004 2RS vs 6004 ZZ vs 6004 Open Bearings
When choosing between bearing types, sealing and speed are key considerations:
6004 2RS: Rubber seals, ideal for dusty or humid environments, minimal maintenance.
6004 ZZ: Metal shields, higher speed capacity but less moisture resistance.
6004 Open: No seals, suitable for clean environments with external lubrication.
For most industrial B2B buyers, 6004 2RS is the preferred option due to better sealing and extended bearing life.
