What Is a 99502HNR Bearing?
The 99502HNR is a type of deep groove ball bearing, commonly used in applications requiring high-speed rotation, low friction, and reliable performance.
Key characteristics typically include:
- Type: Deep groove ball bearing
- Suffix “NR”: Indicates a snap ring groove with retaining ring, allowing axial positioning in housings
- Design: Single-row configuration
- Application: Electric motors, automotive systems, industrial machinery
The “NR” feature is especially important in applications where axial movement must be restricted without additional components.
99502HNR Bearing Cross Reference (Equivalent Models)
Different manufacturers use their own naming systems, so cross-referencing helps buyers find interchangeable bearings. Below are commonly used equivalents (may vary slightly depending on brand standards):
| Brand | Equivalent Model |
|---|---|
| SKF | 6205 NR (possible equivalent) |
| NSK | 6205NR |
| NTN | 6205NR |
| FAG | 6205-2Z-NR (variant with shields) |
| KOYO | 6205NR |
⚠️ Important: Always verify dimensions and suffix meanings before replacement, as slight variations (e.g., seals, shields, clearance) can affect performance.
Dimensions and Specifications
While exact specs should be confirmed with the manufacturer, a typical equivalent like 6205NR has:
- Inner Diameter (ID): 25 mm
- Outer Diameter (OD): 52 mm
- Width: 15 mm
Other technical parameters to check:
- Internal clearance (C0, C3, etc.)
- Material (chrome steel, stainless steel, ceramic hybrid)
- Sealing type (open, ZZ, 2RS)
- Load ratings
How to Choose the Right Cross Reference Bearing
When selecting a replacement for a 99502HNR bearing, consider the following:
1. Match Core Dimensions
Ensure ID, OD, and width are identical. Even small deviations can cause installation or performance issues.
2. Confirm Suffix Features
- NR: Snap ring + groove
- ZZ: Metal shields
- 2RS: Rubber seals
Choose based on your environment (dust, moisture, lubrication needs).
3. Check Operating Conditions
- High-speed → choose precision-grade bearings
- High-load → ensure adequate load rating
- Harsh environments → consider sealed or stainless variants
4. Brand Compatibility
Well-known brands (SKF, NSK, NTN, FAG) ensure consistent quality, but OEM or aftermarket options may offer cost advantages.
Common Applications
The 99502HNR or its equivalents are widely used in:
- Electric motors
- Automotive wheel hubs (light-duty)
- Pumps and compressors
- Agricultural machinery
- Conveyor systems
The snap ring design simplifies installation in housings where axial positioning is critical.
