6315-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6315-2Z/C3GJN is a single row deep groove ball bearing designed for reliable performance in demanding industrial applications. This shielded bearing excels at handling radial loads while also accommodating moderate axial loads in both directions. Its key advantages include high operational reliability, a C3 radial internal clearance suitable for applications with thermal expansion, and pre-lubrication for maintenance-free operation. The combination of precision manufacturing to ABEC 1 | ISO P0 tolerance class and robust construction makes it an ideal choice for applications requiring consistent performance and long service life.
6315-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| 6315 | Basic bearing series with 75mm bore, 160mm OD | Standard deep groove ball bearing dimensions |
| 2Z | Non-contact steel shields on both sides | Effective contamination protection with minimal friction |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
| GJN | Pre-lubricated with high-quality grease | Ready-to-install, maintenance-free operation |
6315-2Z/C3GJN Bearing Structural Features & Performance Benefits
Optimized Deep Groove Design: The raceway geometry ensures smooth operation and efficient load distribution, enabling the bearing to handle both radial and axial loads effectively.
Dual Shield Protection (2Z): Steel shields on both sides provide excellent protection against contaminants while maintaining low friction, contributing to the bearing's 4,300 rpm limiting speed capability.
Enhanced Internal Clearance (C3): The increased radial clearance prevents binding in applications subject to thermal expansion or where interference fits are used, ensuring reliable performance across the operating temperature range of -30°C to 120°C.
Robust Material Construction: Manufactured from chrome steel for rings, balls, and cage, providing consistent hardness, wear resistance, and dimensional stability under the specified dynamic load rating of 25,403 lbf and static load rating of 17,355 lbf.
Factory Pre-lubrication: The GJN grease filling ensures immediate operational readiness and long-term lubrication, making installation straightforward and eliminating the need for initial lubrication.
