6204-2ZN/C3 HT51 Bearing Product Overview & Core Advantages
The 6204-2ZN/C3 is a single row deep groove ball bearing designed for exceptional reliability in demanding industrial applications. This metric bearing features shielded construction (2ZN) on both sides, providing robust protection against contaminant ingress while maintaining smooth operation. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion requirements or where interference fits are used. The inclusion of a snap ring groove on the outer ring enables secure axial positioning and simplified installation. With its precision ABEC 1 | ISO P0 tolerance class and optimized chrome steel construction, this bearing delivers consistent performance across a wide temperature range from -30° to 120°C.

| 2ZN | Non-contact shields on both sides | Effective contamination protection with minimal friction increase |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits |
6204-2ZN/C3 HT51 Bearing Structural Features & Performance Benefits
Enhanced Contamination Resistance: The double-sided non-contact steel shields (2ZN) provide superior protection against dust and particulate contamination while maintaining low operating torque, making this bearing ideal for industrial environments where cleanliness is critical.
Optimized Internal Clearance: The C3 radial clearance ensures reliable operation in applications subject to thermal gradients or where press fits are employed, preventing premature failure due to excessive preload.
Robust Load Capacity: With a dynamic load rating of 2878 lbf and static load rating of 1495 lbf, this bearing handles significant radial loads while maintaining dimensional stability under operating conditions.
Simplified Installation: The outer ring snap ring groove facilitates secure mounting and axial positioning, reducing assembly time and improving system reliability in housing designs.
High-Speed Capability: The limiting speed of 15,000 rpm combined with precision-ground chrome steel components ensures smooth operation across the entire speed range.
