Product Overview and Core Advantages
The 6204-2RSJ is a metric single row deep groove ball bearing designed for reliable performance in demanding applications. Featuring integrated rubber seals (2RS) on both sides, this bearing provides excellent protection against contamination while retaining lubrication. Its deep groove raceway design enables it to handle significant radial loads and moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 precision class with CN radial internal clearance, this bearing offers consistent performance and long service life across a wide temperature range from -30°C to 120°C.
