61812 Bearing Product Overview & Core Advantages
The 61812 is a metric single row deep groove ball bearing designed for high-precision applications requiring reliable radial load capacity. Its compact design, featuring a 10 mm width, makes it ideal for space-constrained assemblies. Manufactured with chrome steel rings and balls, and a stainless steel cage, it offers excellent durability and consistent performance. The bearing's P6 tolerance class ensures high running accuracy, making it a superior choice for applications demanding precision and high rigidity.
61812 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61 | Series designation for extra thin-section, deep groove ball bearings. |
| 812 | Bore diameter code, corresponding to a 60 mm bore. |
| Open (Seal Type) | No seals or shields, allowing for higher speeds and custom lubrication schemes. |
| P6 (Tolerance Class) | Indicates a higher precision grade than standard, providing improved running accuracy and reduced vibration. |
| CN (Radial Clearance) | Standard normal radial internal clearance. |
61812 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The P6 tolerance class and deep groove raceway design ensure precise shaft guidance and high system rigidity, minimizing deflection under load.
- Optimized Load Capacity: As a fundamental single row ball bearing, it is primarily designed to support significant radial loads and can accommodate moderate axial loads in both directions.
- High-Speed Capability: The lightweight stainless steel cage and open design contribute to a high limiting speed of 11,000 rpm, suitable for demanding high-speed applications.
- Versatile Application Range: The specified temperature range of -30°C to 120°C and the absence of pre-applied lubrication (Lubrication: None) provide flexibility for use in various environments and with specialized lubricants.
61812 Bearing Typical Application Areas
This high-precision 61812 bearing is commonly specified in:
- Precision spindles in small motors and medical devices
- Office automation equipment such as printers and scanners
- Instrumentation and precision measuring devices
- Guidance rollers and idler pulleys in material handling systems
- Various industrial machinery requiring compact, high-accuracy ball bearings
