6306-RS1Z/C3GJN Bearing Product Overview & Core Advantages
The 6306-RS1Z/C3GJN is a high-performance single row deep groove ball bearing engineered for demanding applications requiring reliable operation under radial loads. Its design features integrated sealing on both sides, providing robust protection against contamination. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, this bearing offers a precise fit and stable performance across a wide temperature range from -30°C to 120°C. Its construction from high-grade chrome steel ensures durability and a long service life, making it a versatile and dependable component for industrial machinery.
Model Code Breakdown
- 6306: Basic model number denoting a Metric series deep groove ball bearing with a 30mm bore, 72mm outside diameter, and 19mm width.
- RS1: Indicates a contact seal (typically NBR rubber) on one side of the bearing for effective protection against contaminants and moisture retention.
- Z: Indicates a steel shield on the opposite side, providing a physical barrier against larger particulates.
- C3: Specifies a greater radial internal clearance than normal (CN). This is advantageous for applications with significant thermal expansion, interference fits, or where lower operational noise and friction are desired.
- GJN: Signifies the bearing is pre-lubricated with a specific, high-quality grease. This provides immediate, maintenance-free operation upon installation.
6306-RS1Z/C3GJN Bearing Structural Features & Performance Benefits
The 6306-RS1Z/C3GJN combines several key structural features to deliver superior performance:
- Robust Sealing Solution: The combination of a contact seal (RS1) on one side and a steel shield (Z) on the other offers optimal protection. The seal effectively retains grease and excludes moisture and fine contaminants, while the shield provides a durable defense against larger debris, enhancing bearing service life in harsh environments.
- Optimized Internal Clearance: The C3 clearance group allows for accommodation of thermal expansion and interference fits, preventing premature failure due to excessive preload. This contributes to smoother operation and reduced friction.
- High Load Capacity: With a dynamic load rating of 6002 lbf and a static load rating of 3372 lbf, this bearing is capable of handling significant radial loads reliably.
- Maintenance-Free Operation: Pre-lubricated with GJN grease, the bearing is ready for immediate use, eliminating the need for initial lubrication and reducing maintenance requirements.
- Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance, it ensures consistent performance and reliable operation in a wide range of industrial applications.
6306-RS1Z/C3GJN Bearing Typical Application Areas
