6315-2Z/C3HT Bearing Product Overview & Core Advantages
The 6315-2Z/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This shielded bearing offers a reliable solution for primarily radial loads, while also capable of accommodating moderate axial loads. Its key advantages include a high radial dynamic load rating of 25,403 lbf, extended service life, and simplified maintenance due to its integral shields and pre-defined C3 radial internal clearance, making it an excellent choice for applications requiring operational reliability under varying thermal conditions.
6315-2Z/C3HT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6315 | Standard designation for a single row deep groove ball bearing with a 75 mm bore and 160 mm outside diameter. | Defines the fundamental bearing dimensions and type. |
| -2Z | Bearing is equipped with non-contact shields on both sides. | Provides effective protection against contamination while allowing for high-speed operation with minimal friction. |
| /C3 | Specifies a radial internal clearance greater than normal (C3 group). | Prevents preload and binding in applications where thermal expansion is a concern, ensuring stable performance. |
6315-2Z/C3HT Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from high-grade chrome steel for both rings, balls, and cage, this bearing delivers high strength and durability. Its deep groove raceway and optimized geometry contribute to its high radial dynamic and static load ratings.
- Optimized for Speed & Temperature: The non-contact 2Z shields retain lubrication and exclude contaminants with minimal drag, supporting a limiting speed of 4,300 rpm. The specified C3 clearance accommodates differential thermal expansion within an operating temperature range of -30°C to 120°C.
- Maintenance & Operational Simplicity: As a pre-shielded unit supplied without lubrication ("None"), it offers a clean, ready-to-install solution. This design reduces the need for re-lubrication in many applications, lowering long-term maintenance costs.
- Precision & Compliance: Manufactured to ABEC 1 | ISO P0 tolerance class, it ensures consistent and reliable performance. The bearing is also compliant with ROHS and REACH environmental directives.
6315-2Z/C3HT Bearing Typical Application Areas
This versatile deep groove ball bearing is widely used across various industries, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Compressors
