6302-2RSH/C3GJN Bearing Product Overview & Core Advantages
The 6302-2RSH/C3GJN is a single row deep groove ball bearing designed for high reliability and robust performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering operational stability across a wide temperature range. The bearing features integrated seals for contamination protection and is supplied with a high-quality pre-lubrication, making it a versatile and maintenance-friendly solution for general industrial use. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6302 | Basic Bearing Series & Size | Denotes a medium duty, single row deep groove ball bearing with a 15mm bore, 42mm OD, and 13mm width. |
| 2RSH | Seal Type | Features two (2) high-performance NBR contact seals (RSH) on both sides, providing excellent protection against contaminants and moisture ingress. |
| C3 | Radial Internal Clearance | Specifies a greater than normal radial internal clearance, ideal for applications with elevated operational temperatures or tight shaft/housing fits. |
| GJN | Lubrication | Indicates the bearing is pre-lubricated with a high-quality, lithium-based grease suitable for the specified temperature range (-30°C to 120°C). |
6302-2RSH/C3GJN Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing ensures high strength, durability, and resistance to wear, contributing to a long service life under radial dynamic loads up to 2563 lbf.
Enhanced Sealing & Lubrication: The 2RSH contact seals effectively shield the internal components from dust, dirt, and splashing fluids, while the factory-applied GJN grease provides long-term, maintenance-free operation within its temperature limits.
Optimized Internal Clearance: The C3 clearance is a critical feature that accommodates dimensional changes due to thermal expansion during operation, preventing premature failure from excessive preload and ensuring smooth running.
Precision & Speed: Built to ABEC 1 | ISO P0 tolerance class, it offers reliable precision for general industrial applications, supporting a limiting speed of 17,000 rpm.
