6313-2Z/C3WT Bearing Product Overview & Core Advantages
The 6313-2Z/C3WT is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This shielded bearing is designed to primarily handle radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a C3 radial internal clearance for stable operation under thermal expansion, integrated shields (2Z) for contaminant protection, and a wide inner ring for secure shaft mounting. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable, cost-effective performance for a broad range of machinery.
6313-2Z/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6313 | Basic series designation; defines the bearing dimensions (65mm bore, 140mm OD, 33mm width). | Standardized sizing for easy replacement and interchangeability. |
| -2Z | Bearing is equipped with shields on both sides. | Provides effective protection against solid contaminants, retaining factory grease. |
| /C3 | Specifies a greater than normal radial internal clearance. | Prevents binding in applications with high operating temperatures or where fits cause clearance reduction. |
| WT | Indicates the bearing is supplied without lubrication (unlubricated). | Allows for application-specific lubricant selection or use in environments where standard greases are unsuitable. |
6313-2Z/C3WT Bearing Structural Features & Performance Benefits
Optimized Deep Groove Geometry: The raceway geometry is designed for smooth operation and efficient radial load transmission, making it a versatile choice for various applications.
Robust Construction: All critical components—rings, balls, and cage—are manufactured from high-carbon chrome steel, ensuring high strength, durability, and resistance to wear.
Enhanced Contamination Resistance: The non-contact steel shields (2Z) protect the internal bearing components from dust and debris without significantly increasing friction, contributing to a limiting speed of 4,800 rpm.
Thermal Stability: The C3 internal clearance is a critical feature for applications prone to thermal expansion, preventing preload and ensuring smooth, reliable operation across the specified temperature range of -30°C to 120°C.
