126 Bearing Product Overview & Core Advantages
The 126 metric ball bearing is a double row angular contact ball bearing engineered for applications demanding high precision and reliability. Its compact design, featuring a 6mm bore and 19mm outside diameter, provides exceptional space efficiency. This bearing is designed to accommodate significant combined radial and axial loads simultaneously, offering a robust solution for high-speed and high-rigidity requirements. Manufactured from chrome steel and featuring a nylon cage, it delivers superior performance with a limiting speed of 45,000 rpm and is pre-lubricated for immediate use.
126 Bearing Model Code Explained, Specifications & Naming Convention
| Code/Feature | Technical Meaning |
|---|---|
| 126 | Standard metric series designation for a double row deep groove ball bearing. |
| Open (Seal Type) | No integral seals or shields, allowing for higher speeds and easier re-lubrication in controlled environments. |
| CN (Radial Clearance) | Standard normal radial internal clearance group, suitable for most common operating conditions. |
| Lubricated | Pre-greased with a general-purpose lubricant, ready for immediate operation. |
126 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides significantly greater radial stiffness compared to single row designs. This enables it to handle substantial combined loads (radial and axial) effectively, making it ideal for applications with complex force vectors.
- Optimized High-Speed Performance: The lightweight nylon cage ensures stable operation and reduced friction at high rotational speeds, contributing to the impressive 45,000 rpm limiting speed. The open design minimizes heat generation from drag.
- Precision & Durability: Manufactured from high-grade chrome steel, the bearing components offer excellent hardness and wear resistance. The tight dimensional tolerances on the bore diameter, outside diameter, and width ensure precise fit and reliable performance in precision machinery.
- Broad Operating Range: With a temperature range of -30°C to 110°C and compliance with RoHS and REACH, the bearing is suitable for use in diverse industrial environments.
126 Bearing Typical Application Areas
The 126 bearing's combination of compact size, high-speed capability, and robust load capacity makes it a preferred choice in numerous precision applications, including:
- Small Electric Motors and Gearboxes
- Precision Spindles in Dental and Medical Handpieces
- Office Automation Equipment (e.g., Printers, Scanners)
- Instrumentation and Control Devices
- Low-Noise Cooling Fans
