61813 Bearing Product Overview & Core Advantages
The 61813 metric ball bearing is a precision single row deep groove ball bearing engineered for high-performance applications requiring exceptional radial load capacity and dimensional stability. Characterized by its compact design with a 10 mm width, this bearing is ideal for installations with strict space constraints. Manufactured to a P6 tolerance class, it ensures superior running accuracy and is supplied with a standard CN radial internal clearance, making it suitable for a wide range of operating conditions. Its open design allows for versatile lubrication options and facilitates high-speed operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61813 | Standard designation for a single row deep groove ball bearing with a 65 mm bore and 85 mm outside diameter. |
| Open | No seals or shields are fitted. This allows for maximum speed capability and custom lubrication. |
| P6 | Indicates a tolerance class tighter than standard, providing higher running accuracy and reduced vibration. |
| CN | Specifies the standard radial internal clearance group for normal operating conditions. |
61813 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and optimized geometry enable the bearing to support significant radial dynamic load ratings of 2788 lbf and static load ratings of 2855 lbf.
- Precision Performance: The P6 tolerance class ensures tight dimensional control on the bore diameter and outside diameter, resulting in precise shaft positioning and smooth, quiet operation.
- High-Speed Capability: The stainless steel cage provides excellent strength and low friction, contributing to a high limiting speed of 10,000 rpm. The open design minimizes heat generation from drag.
- Robust Material Construction: Both the rings and balls are made from chrome steel, offering high hardness, wear resistance, and long service life under demanding conditions.
- Versatile Application Range: With a temperature range of -30°C to 120°C and no pre-applied lubrication, it can be customized with greases or oils for specific operational environments.
