6202/HR11QN Bearing Product Overview & Core Advantages
The 6202 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. Engineered to primarily support radial loads, this bearing features a simple yet highly effective open design, facilitating high-speed operation and efficient power transmission. Manufactured from high-grade chrome steel and built to ABEC 1 | ISO P0 tolerance standards, it offers reliable, cost-effective performance. Its compact dimensions (15mm bore, 35mm OD, 11mm width) make it an ideal solution for applications demanding a balance of load capacity, speed, and space constraints.
6202/HR11QN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6202 | Standard designation for a single row deep groove ball bearing with a 15mm bore. | Indicates the fundamental bearing type and size. |
| Open (No Seal) | No contact seals or shields are fitted. | Allows for higher limiting speeds and lower operating torque. Requires external sealing in contaminated environments. |
| CN Clearance | Standard radial internal clearance for normal operating conditions. | Provides optimal performance under standard fits and temperature ranges. |
| ABEC 1 | ISO P0 | Standard tolerance class. | Ensures consistent quality and dimensional accuracy for general-purpose applications. |
6202/HR11QN Bearing Structural Features & Performance Benefits
- Deep Groove Raceway: The continuous raceway geometry enables the bearing to handle not only significant radial loads but also moderate axial loads in both directions, offering versatile load-carrying capability.
- High-Grade Chrome Steel Construction: Both rings, balls, and the cage are manufactured from chrome steel, providing high strength, durability, and resistance to wear, contributing to a long service life.
- Open Design for High-Speed Performance: The absence of seals minimizes friction, allowing the bearing to achieve a high limiting speed of 20,000 rpm, making it suitable for demanding high-speed applications.
- Standard Internal Clearance (CN): This clearance is suitable for most operating conditions, accommodating thermal expansion and ensuring smooth, low-vibration operation.
6202/HR11QN Bearing Typical Application Areas
