6004-2RSHNR Bearing Product Overview & Core Advantages
The 6004-2RSHNR is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing features an integral snap ring on its outer ring for simplified axial location and secure mounting within a housing. Its sealed construction with contact seals (2RS) provides robust protection against contaminants, ensuring long-term reliability and reduced maintenance. Engineered with Chrome Steel components and built to ABEC 1 | ISO P0 tolerance standards, it offers a reliable solution for handling significant radial loads with a high limiting speed of 17,000 rpm.
