6306-2Z/C4VT127B Bearing Product Overview & Core Advantages
The 6306-2Z/C4VT127B is a metric single row deep groove ball bearing engineered for high-performance applications requiring reliable operation under radial loads. Featuring integrated shields (2Z) for contaminant protection and a C4 radial internal clearance for stable operation in thermally demanding environments, this bearing delivers robust performance. Its ABEC 1 (ISO P0) tolerance class ensures consistent quality, making it a dependable choice for general industrial machinery where precision and durability are paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6306 | Basic bearing series: Deep Groove Ball Bearing, 30mm bore, 72mm OD, 19mm width. |
| 2Z | Bearing is shielded on both sides. Provides effective protection against solid contaminants while allowing for high-speed operation. |
| C4 | Specifies a greater than normal radial internal clearance. Ideal for applications with significant thermal expansion or where interference fits are used. |
| VT127B | Manufacturer-specific designation for material and process specification. Indicates the use of Chrome Steel for rings, balls, and cage, ensuring high strength and wear resistance. |
6306-2Z/C4VT127B Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and high-quality Chrome Steel construction provide excellent radial load capacity and operational reliability.
- Enhanced Contamination Protection: The double-shielded (2Z) design effectively seals the bearing, extending service life by preventing the ingress of debris. This makes it suitable for environments where re-lubrication is difficult.
- Optimized for Thermal Stability: The C4 radial clearance accommodates dimensional changes due to heat generation or interference fits, preventing premature failure from excessive preload and ensuring smooth running.
- High-Speed Capability: The precision-ground components and shielded design contribute to a high limiting speed of 9,600 rpm, suitable for a wide range of industrial drives.
