6306-2RZ Bearing Product Overview & Core Advantages
The 6306-2RZ is a metric single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with sealed construction, it offers reliable protection against contamination while retaining lubrication. This bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions. Manufactured to P6 tolerance class, it ensures high running accuracy, making it an ideal choice for applications requiring high precision and operational reliability. Its compact design and pre-lubricated state contribute to ease of installation and long service life.
6306-2RZ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6306 | Basic Bearing Series & Size | Denotes a standard metric single row deep groove ball bearing with a 30mm bore, 72mm OD, and 19mm width. |
| 2RZ | Sealing Type | Indicates the bearing is equipped with non-contact rubber seals (RZ) on both sides. This provides effective protection against dust and moisture ingress while minimizing friction. |
6306-2RZ Bearing Structural Features & Performance Benefits
Optimized Internal Geometry & High Load Capacity: The deep groove raceway and high-quality chrome steel construction enable the bearing to support high radial dynamic load ratings of 6654 lbf and static ratings of 3597 lbf.
Robust Sealing & Contamination Resistance: The 2RZ rubber seals on both sides effectively shield the internal components from contaminants, significantly extending the bearing's operational life in harsh environments.
High-Speed Capability & Precision: The combination of a stainless steel cage, P6 tolerance class, and CN radial internal clearance ensures smooth operation, low vibration, and a high limiting speed of 11,000 rpm.
Maintenance-Free Operation: Pre-lubricated with high-quality grease, the bearing is ready for immediate use and requires no relubrication under normal operating conditions within its specified temperature range of -30°C to 120°C.
