6215-2ZN/C3 HT51 Bearing Product Overview & Core Advantages
The 6215-2ZN/C3 HT51 is a metric single row deep groove ball bearing engineered for high reliability in demanding industrial applications. Its core advantages stem from a shielded design (2Z) on both sides, providing effective protection against contaminant ingress while retaining lubrication. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent performance and interchangeability. The bearing features a snap ring groove on the outer ring for secure axial location and simplified housing design. Pre-lubricated with HT51 high-temperature grease, it is ready for immediate use and operates effectively within a wide temperature range from -30°C to 120°C. The combination of a C3 radial internal clearance and robust chrome steel construction makes it an excellent choice for applications with moderate speeds and high radial loads, offering a long service life and operational stability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6215 | Basic bearing series: Deep Groove Ball Bearing with 75mm bore, 130mm OD, and 25mm width. |
| 2Z | Bearing is shielded on both sides. Provides excellent protection against contaminants while being non-contact for low friction. |
| N | Outer ring has a snap ring groove. This feature allows for secure axial positioning and simplifies the housing structure. |
| C3 | Radial internal clearance greater than normal. Suitable for applications with thermal expansion or where interference fits are used. |
| HT51 | Pre-lubricated with a high-temperature grease. Enables reliable operation up to 120°C and offers long-term lubrication. |
6215-2ZN/C3 HT51 Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 15,152 lbf and a static load rating of 10,858 lbf, ensuring durability under heavy loads.
- Enhanced Contamination Protection: The double-shielded (2Z) design effectively seals the bearing from dust and debris, extending service life and reducing maintenance needs in harsh environments.
- Optimized for Thermal Conditions: The C3 internal clearance accommodates differential thermal expansion between the shaft and housing, preventing premature failure due to excessive preload at operating temperatures.
- Simplified Installation and Positioning: The snap ring groove (N) on the outer ring allows for secure axial location, eliminating the need for complex housing shoulders and reducing assembly time and cost.
- Ready-to-Use Lubrication: Pre-filled with HT51 grease, the bearing is lubricated for life in many applications, supporting a limiting speed of 4,800 rpm and operating across a broad temperature range.
