6304-2RS (CN) (CN) Bearing Product Overview & Core Advantages
The 6304-2RS is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. Its key advantage lies in its sealed construction (2RS), which provides robust protection against contaminants while retaining lubrication. This bearing excels at handling radial loads and moderate axial loads in both directions, offering a compact and cost-effective solution. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and is pre-lubricated for long-term, maintenance-free operation within a standard industrial temperature range.
6304-2RS (CN) (CN) Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6304 | Basic Bearing Series & Size | Indicates a medium-duty, metric deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. |
| 2RS | Double Contact Seals (NBR Rubber) | Provides effective sealing on both sides against dust, moisture, and other contaminants. The contact design offers superior protection compared to non-contact shields, making it ideal for harsh environments. |
6304-2RS (CN) (CN) Bearing Structural Features & Performance Benefits
Deep Groove Raceway & Robust Construction: The uninterrupted deep groove raceways on both inner and outer rings are optimized for high radial load capacity and accommodate combined loads. Manufactured from high-grade chrome steel, the bearing components ensure durability and a long operational life.
Integrated Sealing Solution: The 2RS seals are the cornerstone of this bearing's performance. They effectively prevent the ingress of contaminants and the egress of grease, enabling maintenance-free operation and protecting the bearing's precision over time. This is critical for applications where re-lubrication is difficult or impossible.
Optimized for Standard Applications: With a C0 standard radial internal clearance and ABEC 1 precision, this bearing offers an excellent balance of performance, reliability, and cost-effectiveness for a wide range of industrial uses.
