6308-2RS1NTN9/C4 Bearing Product Overview & Core Advantages
The 6308-2RS1 C4 is a sealed deep groove ball bearing designed for reliable performance in demanding industrial applications. As a metric single row bearing, it excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include extended service life through effective sealing, consistent operation due to ABEC 1 precision, and enhanced operational capacity provided by the C4 radial internal clearance, making it suitable for applications with thermal expansion considerations.
6308-2RS1NTN9/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Basic bearing series designation (medium duty, 40mm bore) |
| 2RS1 | Double-sided contact seals (RS1 type) providing superior protection against contamination |
| C4 | Greater than normal radial internal clearance for thermal expansion compensation |
6308-2RS1NTN9/C4 Bearing Structural Features & Performance Benefits
Robust Sealing System: The double-contact RS1 seals effectively retain lubrication and exclude contaminants, significantly extending bearing service life in harsh environments.
Optimized Internal Clearance: The C4 clearance group provides additional internal space, making this bearing ideal for applications where shaft and housing fits or operational temperatures may cause preload conditions.
Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance class, ensuring consistent dimensional accuracy and smooth rotational characteristics for general industrial applications.
Lightweight Cage Design: The nylon cage offers excellent strength-to-weight ratio, contributing to lower friction and quieter operation at the limiting speed of 7,500 rpm.
